Jet neutral beam species measurements by Doppler-shift spectroscopy

Creators

Description

The species mix of the JET neutral injector ion sources is measured several times per pulse for 3 seconds by Doppler-shift spectroscopy. The full-energy ratio increases with beam current: 85% for 60 Amps in hydrogen and 44 Amps in deuterium, and the half and third energy neutrals represent 10 and 5% respectively. No variation greater than ± 2% is observed throughout the pulse
