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.
