Abstract
At the superconducting linear accelerator ELBE electrons with an energy of up to 40 MeV can be generated. ELBE is operated in continuous wave mode. The acceleration is achieved using superconducting RF cavities, which are driven by an analogue low level RF system and solid state based RF amplifiers. The analogue low level RF system was transformed to a digital system based on the MicroTCA standard. It is in user operation since 2020. Here the new digital system and its integration in the ELBE control system is described. Furthermore, the system is characterised by noise measurements, which result in a RMS field stability of the digital low level RF system of 0.01 ◦ in phase and 0.005 % in amplitude. In addition, an algorithm for compensating long term drifts is presented and characterised.
