Abstract :
Ceramic chambers and ferrite kicker magnets were developed in HLS new injection system. The inner surfaces of the ceramic chambers were coated with 0.1 ohm/square metallic Mo layers to meet the requirements of both the penetration of pulse magnetic field and small beam coupling impedance. This paper presents the issues in fabricating these chambers and measurement of their loss factors and wake functions. Broadband impedance parameters of these ceramic chambers were obtained by fitting the measured data
