Abstract
The microwave system of the PLS 2-GeV linac is systematically divided into two parts. One is a drive system, the other is a waveguide system. The drive system consists of an RF signal source (2,856 MHz), a solid state amplifier, a phase shiftkey, a main drive line, and IPA units. There are 11 high power klystrons, 10 SLED-type pulse compressors, and 42 constant gradient accelerating sections in the waveguide network. One module of the waveguide network consists of 63 pieces of waveguide components and four accelerating sections. After installation of the waveguide system, phases for each branch of the system are measured, and phase differences between branches are adjusted within 1 degree. The attenuation of the waveguide system from the klystron output to the input port of each accelerating section is about 0.8 dB. This paper presents the design of the microwave system and its performance.
