Kicker magnet is the beam quick extractor element,which located on the CSRm ring and be constitu- ted of 6 groups of Mn-Zn ferrite and one vacuum tank with 450 mm diameter and 2 250 mm long.In order to meet the vacuum demand of CSRm,the vacuum degree must be better than 3×10~(-9)Pa which is bake- able.In this paper the main parameters,vacuum design,and results will be introduced. Fig.1 shows configuration of CSRm Kicker determined by physical lattice.In the vacuum chamber, there are 6 sectors of high voltage(80 kV)and large electric current(3 000 A)magnets.The total weight
