UHV suitcase

UHV suitcase with base pressure 10-11 mbar allows us to transfer samples between different UHV systems. The aim is to connect different preparation (PLD, MBE) and analytical systems (XPS, 4-probe STM) with our STMs.



Helium liquefier

Liquid helium is used to cool the STMs down to 4 Kelvin or even lower to improve their stability, reduce noise, improve energy resolution and to be able to observe low-temperature phenomena. However, liquid helium is expensive so one needs to recycle helium gas and liquefy it for re-use. Our institute has a central recovery system and an Air Liquid liquefier with capacity of over 40 L per hour.
