Vacuum and Cryotechnics

Lecture and exercises will cover the following topics:
- Gas flow (types of gas flow, inner friction, diffusion of gases, vacuum regimes)
- Vacuum technology (pumps, pressure gauges, materials, design and of vacuum systems)
- Mass spectrometry (for residual gas analysis and temperature programmed spectroscopies)
- Cryogenics (Methods of cooling, physical and chemical phenomena at low temperature)
- Safety issues
The practical course will comprise:
- Hands-on setup of a small vacuum system from components
- Supervised experiments involving sample preparation and the application of standard surface science tools in ultra-high vacuum

After completing the course, the participants shall...
- be able to describe basic principles of vacuum pumps and pressure gauges (for different vacuum regimes)
- judge advantages and disadvantages of different types of vacuum pumps and pressure gauges
- know different methods to reach low temperatures
- be able to design and setup a vacuum system from basic components
- be able to work safely with vacuum and cryogenic systems
