Beam Stability at CTF3
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2012
The two-beam acceleration tested at CTF3 imposes very
tight tolerances on the drive beam stability. A description
of the specialized monitoring tool developed to identify the
drifts and jitter in the machine is presented. It compares all the relevant signals in an on-line manner to help the operator to identify drifts and to log data for off-line analysis. The main sources for the drifts of the drive beam have been identified and their causes are described. A feedback applied to the RF was implemented to reduce the effects. It works by changing the waveform for the pulse compression to compensate for the drifts.
