The GSI is operating a heavy ion synchrotron, which is currently
undergoing an upgrade towards higher beam intensities. It was discovered
that beam losses induce a significant pressure increase in the vacuum
system. In order to detect the time constants of the pressure increase
and decrease, fast total pressure measurements were put into operation.
With the recently installed partial pressure diagnostics it is also
possible to follow up which types of molecules are released. The
presentation will focus on the different techniques applied as well as on
some measurement results. The potential and difficulties of this
diagnostic tool will also be discussed.
