OPTIMIZATION OF MUON CAPTURING IN g-2 RING

We consider the dynamics of muons injected into the g2 ring now under construction at FERMILAB. We present the concept for the pulsed injection kicker magnet that optimizes capture efficiency and minimizes coherent betatron oscillations of stored muons. Some engineering details of the high voltage kicker and pulser are presented.
