In many UHV-systems there is a chronic lack of sample plates, often due to a shortness of storage spaces for them.
It consists of four stacks, each stack featuring five double spaced slots for SHOM flag style sample plates or SHBSOMHM sample holders. The sample plates are held in place by two beryllium copper leaf springs.

This configuration example provides every necessary degree of freedom for full control over your samples in a UHV environment and sample temperatures down to 10 Kelvin by combining a "Boomerax" high precision XY stage with our MZ linear Z-axis drive and incorporating a well-established and very stable Janis ST-400 continuous flow cryostat.
ST-400 He-Flow Cryostat :: As one of the the simplest methods of providing cooling in an ultra-high vacuum environment, the ST-400 has several features that are specific for UHV requirements.
MR63DPV552 Rotary Feedthrough :: This differentially pumped rotating platform provides the means of translating rotation through a vessel wall without losing vacuum integrity
MZ Z-Translator :: The optionally motorized linear Z-axis drive comes into play for accurate lifting and lowering. It's highest quality edge welded bellows fulfill the strictest requirements in terms of leak tightness and durability.
Boomerax MXY Module :: For smooth and exceptionally precise adjustment, it offers a resolution of 2 microns when manually driven and even higher resolutions when motorized.

Manual or Motorized Actuation Alternatives for XY Stage ::
Sleeker and even more refined, yet equally precise and consistent, the new version of our DRVRM manual linear drive for RM and GMD sample transporters is also considerably more affordable than the previous model.
The DRVRM's hand wheel enables especially accurate manipulation, it's high precision spindle drive is coupled to the outer magnet of the sample transporter and controls it's linear motion.
Rotation can easily be locked or undone with a locking screw.
We constantly strive to make your daily work as simple and straight forward as possible, which in this case led to the development of our new LSA3.0 Ion Pump Controller.
It's new and advanced features are the direct pressure display in mbar (rather than a current value that had to be converted), an alarm function for low battery and/or high temperature as well as the built-in temperature measurement and display for a Pt100 sensor, making it the essential controller to have for our LN2-cooled VSN40S UHV Suitcases.For more information...
We are launching a less complex version of our sample transporter with independent rotary motion of the two inner shafts. It's main bearings are of the sliding type to ensure a long lifetime and smooth operation, even over the course of numerous bake out cycles.
The new and simplified design enables lower sales prices compared to our RMDG40 models.
Customizeable in it's lengths of travel and retraction, it's main element is the sample heating stage that's integrated into a complete assembly including a special DN40CF flange with linear/rotary as well as an electrical feedthrough.
A swivable front lid offers easy access. All that's needed is a pincer-equipped wobblestick for quick exchange of multiple crucibles (e.g. for various materials) that can all be used with the same evaporation source.
We have developed an even smaller, lighter and more cost efficient version of our UHV suitcase. The VSN40M is equally reliable yet especially practical wherever space is at a premium.
The Mini NexGeneration UHV Suitcase is the ideal solution for carrying and transferring multiple samples at once under true UHV conditions from one instrument to another. The samples are held in a storage mechanism such as a stack of receptacles or a carousel. Should only a single sample holder need to be stored and transferred, this is also possible using a pincer grip, fork or similar instead of the storage option.
Just like the standard size UHV suitcase, the VSN40M is designed as a modular concept so that it can be adapted to suit your specific requirements.
Our Vacuum Exsiccators are the ideal solution for storing sensitive items under vacuum or in a controlled atmosphere.
Transparency of the polished PMMA as well as the storage box sets ensure a clear view and easy organization of samples. After pumpdown with a membrane pump, the exsiccator holds a base pressure of approximately 25mbar over a period of several months. A pressure meter roughly indicates the vacuum level. The box can be filled with dry Nitrogen or Argon if desired. An overpressure valve is provided for safety reasons.
Standard and portable versions of the vacuum desiccator as well as a complete portable system including a small membrane vacuum pump are readily available.

This time around, our product of the month is an "old acquaintance".
After freezing production of our EV40FC Evaporators in 2014, a limited amount will be ready for production shortly.
Either available fully assembled or as a self build kit, make the most of the opportunity and contact us for more information.
A rugged, versatile evaporator for a wide range of materials such as Ag, Au, Al, Ni, Co, Fe and many more. The evaporant is either placed into a tungsten crucible or the material can be directly evaporated from a rod.
A removable front lid allows easy access to the crucible which can be pulled out for replacement by releasing one single screw. The filling volume of the crucible is up to 500mm3.
The water cooled housing ensures ultra-clean film growth at base pressures in the lower 1E-10 mbar range. The EV40 is equipped with a manually actuated shutter.
Prepare your samples on SHOM flag style plates by inserting them into the shielded receptacle of the HSOMRAD heating stage.
Three filaments rapidly heat the stage up to a maximum operating temperature of 1000°C.
This special flag style sample holder simplifies the process of mounting single crystals (type K005), it's four slits in the retaining plate ensuring safe and level clamping.
If you use another single crystal type and/or need other dimensions, please do not hesitate to contact us.
Our portable UHV-Suitcases are the most refined and easiest way of transporting samples under true UHV conditions between instruments in different locations.
In order to also greatly speed up transfer of your samples from the UHV-Suitcase into the UHV- System, our VSCT40 transfer chamber establishes sufficient vacuum within a fraction of the time needed when baking out conventionally. Vacuum in the VSCT40 is created using a turbo pump as well as a cryogenic pump.
The RMHS40-IVBR-TSRMBD serves as a vertically mounted manipulator, commonly used for sample insertion into cryogenic SPM's.
The layout of these systems calls for long travel and precise manipulation.
The RMHS40 sample transporter features a specially treated hollow shaft that offers the necessary straightness, lighter weight and crucially it also avoids excessive thermal conduction.
Strongly recommended for safety reasons is the inclusion of an IVBR in-vacuum brake that prevents the inner shaft from suddenly dropping, should the magnetic coupling be let go by accident.
Facilitating the handling of such long sample transporters, the TSRMBD belt drive provides quick elevation over longer distances using it's belt. Two hand wheels enable precise linear as well as rotary positioning.
Pictured below: IVBR In-Vacuum Brake
Application example (with UHV cube) shown: Scanning tunneling microscope setup operating in UHV, very low temperature (T<0.1K) and high magnetic field (B>15T). The hollow shaft, belt-driven sample transporter by Ferrovac enables top-loading of the sample and tip holders from the transfer chamber (UHV cube) down to the STM head.

Used to align transfer axes of manipulator-to-chamber or chamber-to-chamber systems, port aligners are indispensable for most sample manipulations and transfer mechanics in UHV.
While all types of port aligner allow for angular and linear adjustments and compensation, the "HEX" models additionally enable lateral axis displacement.
Thanks to this enhanced flexibility, the axis of for example a sample transporter can be aligned with two different sample exchange positions in just one setting.
Hexapod port aligners are also especially sturdy.
Thanks to very recent optimizations in the design and production process of our hexapod port aligners, we've been able to adjust their prices accordingly:
|CHF 1'450.00||CHF 1'870.00|
|CHF 2'140.00||CHF 2'580.00|
Machined from a solid block, they are available in a variety of shapes and materials to suit specific requirements like high heat resistance or non-ferromagneticity. We also supply matching SHOM plates in a great variety of materials.
Secured in the RECOM by leaf sprung Ruby spheres, the sample plates glide over these point contacts with very low friction.
RECOMs are the fundamental building block for a whole host of sample storage solutions such as revolving carriers for SHOM plates.
Please contact us to find your matching off the shelf or customized sample plate receiver and/or storage solution.
Using longer sample transporters, it can be hard or impossible to simultaneously look inside the chamber over the full length of travel. Thus alignment checking is a step-by-step process, making for cumbersome handling.
Our new TSRMKG extension for remote manipulation is mounted on a guide rail for the sample transporter and enables full control while standing close to the system - for constant visual monitoring.
The finishing touches to an all-round sample handling and storage solution were realized mid-year with delivery to the University of California following soon after.
The system was developed in close collaboration between the engineering department of Ferrovac and Alexander S. McLeod and Michael Goldflam of the Department of Physics at UC San Diego.
Once fully assembled and operative, the first results and feedback were altogether positive:
Michael Goldflam andAlexander S. McLeod of the Basov Infrared Laboratory, UC San Diego
Developers and builders of the cryogenic scanning near-field optical microscope
The system (pictured above) consists of a customized KS load lock cross and chamber, a WMG40 wobblestick with custom-made PGWMS pincer, a pair of MD linear/rotary feedthroughs equipped with eightfold RECOMSTACK sample storage stacks and the elementary RECOMEC13S receptacles and SHOMEC13 sample plates with electrical contacts.
In very limited space, the approach to the interchangeable probe and sample plates is only possible at a 47° angle, with the probe also tipping forward. A special pincer design accounts for these issues, making access to and exchange of the samples a smooth affair.
By simply twisting the wobblestick to one or the other side and back, the sample plate is held either straight for exchange with either storage stack or at an exact 47° for access to the microscope.
The transparent (PMMA) panels provide a clear view of the contents for easy organization and the pump is mounted in a compact box that can be mounted/detached to an EXSICA3P desiccator - for on the spot pump down pretty much anywhere you are, as it operates on 12 Volts.
So even if you're truly "in the field" you can for example plug it into your car's 12V DC socket adapter to run it. A mains power adapter is also included.
Newly complementing our heating solutions are the modularly configurable resistive sample heating items presented below.
The basic building block is the RECOMHTR1001 heatable receptacle for sample plates, that fits directly on top of a HTR1001 Boralectric™ resistive heating element. For the resistive heater to function proficiently and reliably at high temperatures, material choice and a thoroughly considered construction of the stage are required.
A given with our pre-configured heating stages:
Motorization of manipulators provides reliable, safe and precise movement, positioning and handling. Implemented in our motorized linear/rotary drives are the necessary prerequesites: a fine step resolution and a sturdy construction.
The motorized precision drive unit allows for easy, independent manipulation of the linear and rotary axis.
The HOENCOL energy collimator presented here was developed for the Swiss Free Electron Laser facility (SwissFEL) in close collaboration with the Paul Scherrer Institute. It consists of four magnetic dipoles with a collimator block system installed between the two central dipoles.
The energy collimator acts as a filter to protect the undulator line from parasitic electrons.
In order to vary the energy acceptance of the system, two motorized linear drive units move the shielding blocks along the horizontal axis perpendicular to the direction of the e-beam.
In order to resolve mechanical stress in the process of opening/closing the gap with the linear drives, possible angular errors are compensated by the alignment units. These consist of massive triangular plates held by three sturdy steel studs which are used for the initial alignment.
The edge welded belows allow for the necessary angular freedom.
Due to potential electromagnetic disturbances caused by the stepper motors, these are placed 0.5 m away from the electron beam axis.
With an accuracy of less than 1 micron, an integrated linear encoder measures the linear displacement of the alignment unit.
Linear force is transmitted via torque shafts to protect the alignment units' belows from distortion.
Schematic Layout of SwissFEL Aramis beamline (left) and setup of various components on it's girder (right), showing the position of the energy collimator.
In order not to affect the beam quality, the surface and positioning of the two motorized shielding blocks must fulfil the high requirements specified below. The support beams and their supporting structure were laid out with an extreme stiffness using FEM (finite element method) to optimize shape and pocket geometry.
This simulation shows a support beam hanging freely without any base and with a 7kg load. In an overscaled representation, the displacement of the tip is calculated to be less than 0.05 mm.
The PCPLS is a novel cathode preparation and loading system designed and built for the Swiss Free Electron Laser facility (SwissFEL) at PSI.
It enables the preparation and exchange of the RF photogun's cathode without breaking the UHV chain. A prerequesite for maintaining the quality of the cathode surface, which is essential.
The SwissFEL electron source is an RF photo-injector in which the photo-cathode plug can be exchanged, all under UHV conditions. Without a load-lock, the cathode exchange takes about one week and the cathode surface gets contaminated in the atmosphere during installation, leading to unpredictable quantum efficiency (QE) fluctuations.
These time and contamination issues motivated the construction of a load lock system to prepare and insert cathodes into the photo-injector, doing away with the need for venting the gun. Now using the vacuum suitcase for the cathode exchange between the preparation chamber and the gun loading chamber, the exchange requires only half a day (including RF conditioning of the new cathode, tested on Cu_17).
The cathode loading system consists of three chambers:
This three-part system allows the preparation of the cathode surface with methods like annealing. The QE can be checked with a laser and the plug can be inserted into the gun without breaking the vacuum. This will eventually allow the use of semiconductor cathodes like Cs2Te.
The PCPLS system was successfully installed and tested at the SwissFEL injector Test Facility (SITF).
A magnetically coupled manipulator arm can grab the plug (right) out of a parking holder and safely transfer it linearly over half a meter distance under ultra high vacuum. In each of the 3 chambers a rotatable carousel (below) can hold up to 4 cathode plugs.
The figure to the right shows how the vacuum suitcase is connected to the gun loading chamber. The fine adjustment knob of the magnetically coupled manipulator keeps the cathode pushed into the gun during operation.
The quantum efficiency of the cathodes depends on three theoretical parameters: the work function, the surface reflectivity and the local electric field (for a given laser wavelength). Contamination and roughness directly affect these parameters. The PPLS enables optimized preparation procedures and actions for the cathodes.
Cathode surface cleaning is done in the preparation chamber. The most effective way to remove surface contaminants is to heat up the cathode plug for several hours. The preparation chamber is equipped with a heating rod which can be directly inserted into the back of the cathode plug. Thanks to the vacuum suitcase, the cathode is protected from exposure to atmosphere during transfer. Therefore preparation processes such as Dicaesium Telluride vapor deposition can be included.
The deposition chamber is equipped with an easily exchangeable aperture in front of the cathode (for variation of the deposition area)
and a quartz micro-balance. The cathode is loaded from the left and the evaporation source from the right.

Motorization of manipulators provides reliable, safe and precise movement, positioning and handling. Implemented in our motorized sample transporters are the necessary prerequesites: a fine step resolution and a sturdy construction.
Where different users operate, automation is especially advantageous and also saves valuable working time.
Shown in the video below is a stepper motor-driven linear drive for RM and GMD sample transporters. The motorized drive allows for automatic and reproducible extension of the shaft. Rotary motion is done manually.
Pictured right is a motorized linear and double rotary drive with pincer grip for SHOM sample plates. The separate rotation of each shaft enhances operation of the pincer by being able to open/close and also rotate it.

We have designed, built and tested a new instrument for soft x-ray scattering experiments. IRMA-2 is a UHV set-up for elastic and coherent scattering experiments developed at the SEXTANTS beamline of the SOLEIL synchrotron. Applications will be in the field of solid state physics, with emphasis on the investigation of the magnetic properties of artificially structured materials.
A versatile heating stage for SHOM sample plates. The Positive high voltage applied to the sample, attracts free electrons generated by a tungsten filament which is placed on the rear side of the plate. With this very effective way of heating, temperatures of ~2000°C can be reached within a few seconds.
