Design optimization of a pulsed positron beam system at IGCAR, Kalpakkam

A pulsed positron lifetime system has been designed using RF pulsing scheme. The mechanical design of the ultra high vacuum(UHV) beam line has been made to incorporate the basic requirements of a magnetically guided slow positron beam as well as that of an RF pulsing system consisting of a reflection type grid based chopper, a double gap pre-buncher and a main buncher. The trajectory and the timing characteristics of positrons have been simulated using SIMION code. The amplitude of the chopper and buncher RF voltages has been optimized based on these simulations.
