Abstract
This thesis evaluates the concept of characterization process of ultra-high vacuum
system, known as SEA5 Serial Expansion Apparatus at RISE Research
Institutes of Sweden.

To produce precisely known pressures in the medium, high, and ultra-high
vacuum range for gauge calibrations, the volume expansion system is often
used for that purpose. There are different methods to determine the volume or
the expansion ratios in such system. The two methods used during the characterization
process are the spinning rotor gauge and the gas accumulation, by
measuring the pressure before and after an expansion.

Furthermore, implementing the methods in the control software developed
in LabView for fully automated characterization process. The... (More)
