Beam Loss Monitors

Abstract:

For the sensitive process of slow extraction from a synchrotron a reliable control of the beam losses is needed. We have tested several types of particle detectors mounted at the extraction path of the SIS: A BF3-tube for pure neutron detection, a liquid and a plastic scintillator detecting neutrons, gammas and charged particles and an Ar filled ionization chamber mainly sensitive to charged particles.

While the count rate is quite different, the time evolution of all detector signals during the spill are similar, but the plastic scintillator has the highest dynamic range. This type is going to be used for beam alignment.
