Description

The Heavy Ion Fusion Group at Lawrence Livermore National Laboratory has for several years been developing the world's first circular ion induction accelerator designed to transport space charge dominated beams. Currently, the machine extends to 90 degrees, or 10 half-lattice periods (HLP) with induction cores for acceleration placed on every other HLP. Full current transport with acceptable emittance growth without acceleration has been achieved. Recently, a time stability measurement revealed a 2% energy change with time due to a source heating effect. Correcting for this and conducting steering experiments has ascertained the energy to an accuracy of 0.2%. In addition, ... continued below

Recently, a time stability measurement revealed a 2% energy change with time due to a source heating effect. Correcting for this and conducting steering experiments has ascertained the energy to an accuracy of 0.2%. In addition, the charge centroid is maintained to within 0.6-mm throughout the bend section. Initial studies of matches dependencies on beam quality indicate significant effects.
