Abstract :
A fast beam chopping directly in a surface-plasma H- ion source was proposed and a preliminary test has been examined. The converter bias voltage is modulated and the extracted H- beam is observed. The direct fast chopped H- beam extracted from the ion source responds to the modulated converter bias voltage as expected. The extracted beam using this method has been accelerated by the 40 MeV linac
