A High Repetition Rate Ultra Fast Hybrid Switch Module for Project X MEBT Chopper
Tang, Tao.
In order to serve several experiments simultaneously, the Project X requires a programmable chopping system to deflect bunches from the initially 162.5MHz CW H-beam. A helical 200 Ohm deflector is proposed, which needs a /-500V variable pulse length driver with ~2 ns rise/fall time at an average repetition rate of 33 MHz. The SLAC Hybrid MOSFET/driver Switch Modules (HSMs) have demonstrated 1ns switching of 1 kV into a 30 Ohm load during 6 MHz burst operation. This paper presented development a... Show Full Abstract
In order to serve several experiments simultaneously, the Project X requires a programmable chopping system to deflect bunches from the initially 162.5MHz CW H-beam. A helical 200 Ohm deflector is proposed, which needs a /-500V variable pulse length driver with ~2 ns rise/fall time at an average repetition rate of 33 MHz. The SLAC Hybrid MOSFET/driver Switch Modules (HSMs) have demonstrated 1ns switching of 1 kV into a 30 Ohm load during 6 MHz burst operation. This paper presented development and preliminary testing results of a new HSM, which is optimized for the Project X chopper driver parameters. Show Partial Abstract
