The Berkeley 2 MV heavy ion fusion injector

An update on the development of the 500-mA/beam sixteen-beam injector being built at Lawrence Berkeley Laboratory is presented. An inductively graded Marx bank provides the acceleration potential on the electrostatic column. A carbon arc source provides the pulsed current for the injector. Recent results on extracted beam parameters, column performance, generator performance and system design changes are reported. The carbon ion beam is diagnosed with Faraday cups and with a double-slit emittance measurement system. Controls for the final machine are also discussed
