Multishot and Multichannel Fast Ejection

A new fast beam extraction facility has been installed in the CERN proton synchrotron. The system provides, during the same machine cycle, up to three partial fast ejections to the same or different experimental areas at minimum intervals of 150 to 200 ms. The number of proton bunches at each ejection may be varied continuously, and furthermore the system may be programmed to perform different ejection schedules from machine cycle to machine cycle.
