Abstract :
Complete design, assembly, and testing of 200 MW modulators are in progress at the Pohang Accelerator Laboratory (PAL) for the full energy injection linac system of the Pohang Light Source (PLS). A 150 MW pre-prototype modulator (350 kV, 3.5 μs flat-top width, and 840 Ω load) has been assembled and tested up to 175 MW. Design, construction, and test of a 200 MW prototype modulator (400 kV, 4.4 μs flat-top width, 800 Ω load) has also been completed. Eleven units of main 200 MW modulators are under construction, and their assembly is expected to be completed in 1993. This paper presents the design and the current status of performance results of 150 MW and 200 MW modulators
