HIGH BRIGHTNESS H-SURFACE PLASMA SOURCES *

Novel modifications of H source designs have been proposed. A new source under development is an advanced version of a Penning DT SPS (Dudnikov-Type Penning Surface Plasma Source) which will generate brighter beam in noiseless discharge, deliver up to 20 mA average current with better electrode cooling using new materials, and have longer lifetime, fast beam chopping capability, and reduced cesium loss.
