OPTIMISATION OF THE VACUUM SYSTEM OF A LINEAR ACCELERATOR

Peter Kovác - Aleksandr V. Tikhomirov - Mohammed N. El-Shazly - Jozef Dobrovodský

   The pressure distribution in the model vacuum system consisting of several volumes, pumps and gas sources was calculated using the analytical solutions of corresponding differential equations. The results were incorporated into the recently developed algorithm for similar calculations developed in FLNR~JINR Dubna, to enhance its precision. A modified code was then used to calculate the pressure distribution over the linear ion accelerator of FEI~STU. Several possibilities how to improve the vacuum conditions in the accelerator system are proposed.

Keywords: vacuum, pressure distribution, ion beam loss, computer simulation
