SIS18 Beam Experiments for the Verification of the RF Control System for Dual Harmonic Operation
In the scope of the SIS18 upgrade, dual harmonic accel- eration is an important requirement in order to reach the target beam intensities. Since about 6 years, the RF de- partment has been developing digital low-level RF (LLRF) components that are flexible enough to allow various applications such as single-harmonic cavity syn- chronization, beam phase control, longitudinal feedback, etc. Therefore, it was now possible to use the new modu- lar software and hardware components for first beam ex- periments on dual-harmonic operation.
