Comparison of deuterium and hydrogen dissociation with a surface-wave discharge dissociator and a SiO2 sputtered nozzle

The deuterium dissociation degree has been measured using a new type of dissociator based on a Surface-Wave Discharge (SWD) at 2.45 GHz, equipped with a SiO2 sputtered conical-shaped aluminum nozzle. Deuterium dissociation measurements are reported as function of oxygen fraction, microwave power and gas throughput, and compared with hydrogen dissociation values obtained with the same dissociator.
