Abstract:
A turn key 50 MeV linac is under construction, in order to inject electrons into the booster of BESSY II synchrotron in replacement of the existing microtron. The linac will deliver electron beams according to two operation modes: a Short Pulse Mode (1 to 5 pulses - 0.35nC each) and a Long Pulse Mode (40 to 300 ns - 3nC). We have calculated the beam dynamics, using our in house code, PRODYN [1], from the gun to the end of the linac. This code has been previously used for the beam dynamics of the SOLEIL and ALBA linacs [2] [3]. The beam behaviour, such as the radial control, the bunching process, the energy spread and emittance are analyzed.
