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.

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