Vacuum in an accelerator system - calculations and measurements

• The importance of different sources of gases in a vacuum system is discussed and the definitions of different flow regimes are presented. The conductance is given for a few different, typical geometries in an accelerator vacuum system. The theory is applied to the vacuum system of the Lund electrostatic tandem accelerator and a pressure profile through the accelerator is calculated. The quality of this simplified method is discussed.
