摘要The beam loss during the single turn extraction from a Rapid Cycling Synchrotron (RCS) with high beam power is of important concern. The extraction kickers are usually designed to have exigent total strength to avoid the beam loss. This will increase the construction cost or reduce the kickers' availability during operation. This paper introduces a method employing DC bump magnets and beam collimation during the early acceleration stage in order to reduce the requirement to the extraction kickers and the beam loss at the extraction. The orbit bump at the extraction septum produced by small DC magnets will collapse during the acceleration, and this will lower the requirement of the orbit separation by the kickers. At the same time, the similar orbit bump at the transverse collimators will allow the beam cleaning in the early acceleration stage and result in much smaller beam emittance at the extraction. The combined effect gives the low beam loss extraction with significantly lower kicker strength. The different ways of applying the method in the China Spallation Neutron Source are also presented.
