Design of intelligent tuning system for a high current induction accelerator

An intelligent tuning system for the high current LIA is being designed at Laboratory of Accelerator Physics and Application, Institute of Fluid Physics. The goal to build the system is to adjust the beam centroid trajectory automatically for “Dragon - I”, which is a 20MeV, 2.5kA, 60ns pulsed electron LIA under construction. The simulation results show that to obtain pulsed electron beams with good quality and to reduce corkscrew amplitude, beam trajectory tuning is necessary. Three tuning methods adopted in the system are tuning manually, computer clone tuning and intelligent tuning. Both simulation and experiments have been performed to obtain the tuning curve of the first steering coil in the first cell. Details of the design, the tuning strategy and some of the tuning simulation and
