摘要

The injecting section and the cooler section are apart from each other at CSRm, while the electron cooler systemis installed at the injecting section of CSRe[1]. So for the CSRe we not only need to satisfy the beam injectingcondition but also need to satisfy the beam cooling condition. At present, we use the ramping bump and the kickerto inject beam, and after injection the bump disappear quickly and the beam goes to the cooling orbit and begincooling. This method has a disadvantage that the beam cooling condition cannot be satised until the bump isdown. In the past year, we try to nd a new method to correct the orbit of cooler section. Instead of using rampingbump we use the xed bump to satisfy the injecting and the cooling condition at the same time.
