Osnova předmětu

1. Introduction: Importance and use of vacuum and cryogenic technique. Vacuum ranges.
2. Free gases: In a static state. Ina dynamic state - gas diffusion and effusion, gas internal friction, energy transport. Gas flows - kinds and characteristic quantities, vacuum conductance, pumping speed.
3. Bound gases: On the surface - physical and chemical adsorption, characteristic quantities. Evaporation and condensation - steam tension. Gases in solids - gas solution and diffusion.
4. Vacuum acquisition: mechanical, steam and diffusion pumps - characteristics, construction. Connection of diffusion and rotary pump. Cryosorption, sorption and iont pumps, characteristics and construction.
5. Vacuum measurement: Absolute measurement methods. Indirect measurement methods - thermal and ionization gauges. Calibration of gauges. Measurement of partial pressures. Leaks in vacuum systems - search methods, leak detectors.
6. Vacuum systems: Basic principles of construction of vacuum systems. Elements of vacuum devices - removable and fixed links. Materials for vacuum technique.
7. Methods and materials of cryogenic technique: physical properties, refrigerants, gas liquefaction, storage.
8. Cryogenic systems: design and construction, low-temperatures measurements.
