Content focus:
- Introduction: The importance and use of vacuum and cryogenic technology. Industries vacuum.
- Free gases: In a static state. In the dynamic state - diffusion and effusion of gas,
internal friction of gas, power transmission. Gas flow - types and characteristic quantities, vacuum conductance, pumping speed.
- Bound gases: On the surface - the physical and chemical adsorption, characteristic variables. Evaporation and condensation - steam tension. Gases in solids - dissolution and diffusion of gases.
- Generating Vacuum: mechanical, steam and diffusion pumps - characteristics, construction. The combination of diffusion and rotary pumps. Kryosorption pumps, sorption and ion pumps, characteristics and construction. Measurement of vacuum, absolute measuring
methods. Indirect measuring methods - thermal and ionization gauges. Calibration of manometers. Measurement of partial pressures. Leaks in vacuum systems - search methods, leak detectors.
- Vacuum system: Basic principles of construction of vacuum systems. Elements of a vacuum apparatus - removable and fixed links. Materials for vacuum technique.
- Methods and materials of cryogenic technique: physical properties, refrigerants, gas liquefaction and storage.
- Cryogenic systems: design and construction, low-temperature measurements.
