Mechanical workshop

A dedicated workshop for UHV equipment is part of our chair. The “Feinmechanikermeister” Jürgen Linzmayer and Klaus Wörfel are experienced in constructing, building and repairing UHV components and other parts related to UHV vessels. They support the development of new parts in many points: choice of the right materials, effective designs with producible shapes and professional CAD drawings. Some highlights are:

  • ErLEED-Optics
  • Knudsen cell evaporator with two cells
  • LT-UHV STM system with in-situ transferable scan head

The labs at the chair gain a lot from the up-to-date stock of spare parts and the fast repairs of broken components by the workshop.

Jürgen Linzmayer and Klaus Wölfel also take care of  health and safety at the chair.

Copper sample manipulator head with Molybdenum sample holder. A Cu single crystal is mounted inside the sample holder.
Transferable UHV-LT STM scan head.
The workshop is equipped with a CNC-machine tool since 2018 (CNC = Computerized Numerical Control)
Stick slip coarse approach. Rubin balls and Tungsten Carbide are used at the contact points.
Electrical connection stage on a Joule-Thompson cryostat inset.
A customized indexing head allow the transfer between CNC-molding cutter and turning lathe without wrapping and aligning working piece again.
UHV rope winch. It is used to transfer the LT-STM into the cryostat tube.
Evaporator for ionic liquids.
Recipient of a gold evaporator.
CAD construction of a Joule-Thompson cryostat inset.
Artistic view on a turning lathe.
Another version of an ionic liquid evaporator
The ErLEED was developed at this chair and is the blueprint for modern commercial electron optics.
