Thu 30.11.2017 picovac has successfully presented new products from UHV Design and introduced the most flexible deposition system HEX from Korvus Technology as well as the portfolio from Leiden Probe Microscopy on the campus of the GSI in Darmstadt as part of the GSI Roadshow program.
When transmitting rotary motion through some sort of chamber wall (more general: environmental boundary) there are a variety of engineering solutions available, from simple O-ring seals as might be used to contain liquids or even vacuum at the medium vacuum level, through to differentially pumped O-rings and Ferrofluidic drives for high vacuum (HV).
However, due to the much more stringent requirements in terms of leak tightness and materials outgassing properties, transmission into an Ultra High Vacuum (UHV) environment is very much more challenging. There’s a lot more to learn about the UHV Design Magi Drive series. Click here to download the Technical Bulletin.
Wobble sticks and magnetically coupled transfer arms are the most commonly used sample transfer options in HV and UHV systems. The challenge of sample transfer will vary greatly depending on the geometry of the system, the transfer distance and available mounting options for sample transfer devices.
In addition, the placement of viewports must be considered to ensure clear line of sight at the appropriate stage of the transfer process. (e.g. when inserting a flag sample holder into an analytical stage).
Wobble sticks provide a simple method of moving sample holders such as the various flags and pucks over relatively small distances (typically <400mm) in situations where the user requires the freedom to manipulate the sample using a combination of rotation, linear and tilt movements. Please see UHV Design application note.
Thanks to everyone visiting booth 91-93 at the DPG Spring meeting 2017 in Dresden and special thanks to our partners UHV Design, Korvus Technologies and Leiden Probe Microscopy for making this a very successful event.
Korvus Technology are proud to announce that the first of the new HEX-L deposition systems has been shipped. The HEX-L accommodates 6″ wafers (150mm). With the use of differentially pumped O-rings the system can get down to the low minus 8’s while still maintaining its modular and user friendly design. The HEX-L is equipped with a rotating sample stage, 300l/s turbo pump and dry scroll pump as standard and can be easily tailored to your specific research requirements.
UHV Design and picovac will exhibit at the Eighth Joint BER II and BESSY II User Meeting held in Berlin-Adlershof during December 7th - 9th, 2016. We’ll be delighted to meet you at our booth #33.
The Sample Parking Stage has been designed to accommodate Omicron, Specs and Aarhus Flag style sample plates. It is intended to store multiple samples in the UHV chamber and comprises either one or multiple carousel plates, each of which can accommodate 4 flag style sample plates.
The carousels are mounted from a magnetically coupled rotary drive (MagiDrive) such that each can be presented in turn to the transfer mechanism, whether that be a Wobble Stick, magnetically coupled transfer arm (PowerProbe) or linear rack and pinion transfer device.
The new slimline design of Wobble Stick from UHV Design offers both in-line and right-angled configurations with the choice of passive or gripper mechanism plus end-effector. Each range is offered with optional standard sample transfer forks to transport industry-standard sample holders such as flags, pucks and stubs.
This month’ news is the launch of picovac. We’re keen to start service for our customers and at this point express our thanks to everybody supporting us lately. We extend our special thanks to our cooperation partners UHV Design Ltd, Korvus Technology Ltd, Leiden Probe Microscopy BV and NanoTech Consulting Ltd.
