A method for increasing the multiturn injection efficiency in AG proton synchrotrons by means of skew quadrupoles

An increase of the injection efficiency due to linear coupling is shown to work in AG Proton Synchrotrons for Q/sub H/-Q/sub V/=p. The system is in operational use at the CERN Proton Synchrotron Booster (PSB) to reach intensities above 10/sup 13/ ppp. An intensity increase of 20% is achieved at the...

description An increase of the injection efficiency due to linear coupling is shown to work in AG Proton Synchrotrons for Q/sub H/-Q/sub V/=p. The system is in operational use at the CERN Proton Synchrotron Booster (PSB) to reach intensities above 10/sup 13/ ppp. An intensity increase of 20% is achieved at the expense of a slight vertical blow-up, which is however not noticeable for high-intensity beams as their emittance is already increased because of an integer stop-band. A comprehensive model is presented, which describes the efficiency as a function of several parameters, such as the coupling strength, injection geometry and Q-values. (7 refs).
