Effect of tapered magnetic field on expanding laser produced plasma for heavy ion inertial fusion

Abstract

The ion source performance required for heavy ion inertial fusion (HIF) is beyond that used for current operating particle accelerator facilities. Ion sources are required to provide several tens to hundreds mA of low charge state heavy ions (q/A~100-200), such as Bi1+ to minimize the difficulty of a final focusing system caused by space charge repulsion force.[1] A laser ion source (LIS) is one of a promising candidate of such ion sources...
