An insertion device of 6T super-conducting wiggler has been installed in the injection section of the Taiwan Light Source (TLS) electron storage ring. A ceramic kicker-chamber downstream the device subjects an intensive synchrotron radiation on both side-wall. A water-cooled copper absorber, installed inside the ceramic chamber to shield the inner wall from irradiation, might cause serious problems. The problems contain the induced arcing between the absorber and the ceramic chamber, the induced interference magnetic field, etc. during the ignition of the kicker magnet. The efficiency of beam injection and the beam life time could be seriously degraded. The solution to cure those problems, the design of the absorber, and the commissioning results will be described in this paper.
