摘要
CSRm injection beam line is the transitional section between HIRFL post beam line and CSRm. HIRFL post beam line's vacuum degree is about 10-6 Pa and CSRm's designed average pressure is 6×10-9 Pa, so CSRm injection beam line is a very important section which must finish three order of magnitudes pressure transition from 10-9 to 10-6 Pa.
