Vacuum Training at the 1st Vacuum Symposium
Two training seminars will run each day with the programme repeated both days.
The seminars will run approximately 1.5 - 2 hours each consisting of informal lecture/tutorial style.
Module 1 (AM) Vacuum – basic principles
Schematic representation of a typical vacuum system.
Specifying a vacuum – pressure and partial pressures.
Air, water vapour and rarefied gas.
The molecular description of a gas. Mean free path.
Fluidic and molecular states of gas, Knudsen number
Gas flow – viscous and molecular
Specifying flow – throughput, pumping speed and conductance
Sources of gas in a vacuum vessel. Outgassing
The pumping process, pumping times and ultimate pressure
Module 2 (PM) Vacuum in practice
Pumps: classification and operating range.
Working principles of rotary oil-sealed, scroll and turbo-molecular pumps (and/or others as requested/advised)
Pressure gauges: classification and operating range.
Working principles Pirani, capacitance diaphragm and ionisation gauges (and/or others as requested/advised)
The quadrupole residual gas analyser, interpretation of spectra
Examples of systems
