Title :
Petra bunch rotation
Author_Institution :

Abstract :
The upgrade of the Petra bunch rotation scheme for protons is described, Bunch compression in Petra is necessary for stable longitudinal transfer matching with Hera. The influence of beam loading in Petra has to be taken into account for currents above 50 mA even though a strong fast RF feedback system is installed. Amplitude modulation in a short push-pull cycle is chosen for bunch rotation and a bunch length compression factor of 0.7 is established with tolerable distortion
