Description
The 3 ms long RF pulse at ESS will make Lorentz force detuning (LFD) significant for the superconductive cavities and at 14 Hz repetition rate some ringing might still be present at the start of the next pulse. An iterative compensation algorithm have been developed to reduce the required overhead to maintain a constant cavity field. It is based on detuning calculation of each pulse and provides a voltage to the Piezo stack to counteract LFD. Design details and initial results will be presented.
