Alkali deuteride negative ion source development plan

A three phase program is described for the development of neutral beam systems. In the first phase, concluded in May, 1977, the laser initiated source was characterized. In phase two, scheduled for completion in September, 1978, negative ion confinement and extraction are investigated using laser energy deposition as a baseline method to produce D-. In addition other energy deposition schemes are studied in order to define a baseline energetic beam source system. The third phase is devoted to producing an integrated baseline system and scaling it up in current and energy to meet magnetic confinement system requirements
