Multicusp Ion Source, Turnkey System
Turnkey Multicusp Ion Source System • Filament-Driven Multicusp • TRIUMF Licensed
ISV.F-40
A D-Pace Turnkey System provides the equipment and supporting infrastructure required to generate, control, and measure the ion beam. This system incorporates and of D-Pace’s Volume-Cusp Negative Ion Source’s based on technology licensed from TRIUMF, along with the required power supplies, vacuum and gas-handling equipment, controls, power distribution, safeguarding system, and integrated cooling circuit. High-voltage, X-Ray, and Microwave hazards are housed within an safeguarded enclosure. The customer is responsible for providing the required facility services, including AC power, air for pneumatics, and cooled facility water.
