This year we improved pre-ionization to a level that results in injected gas 10 times less than in 2004 Novel pre-ionization system –Injects gas and 10-20kW of 18GHz ECH in a cavity below the lower divertor gap –Successfully tested, achieved discharge generation at injected gas amount of < 2 Torr.Liter Fast Crowbar system –Rapidly reduces the injector current after the CHI discharge has elongated into the vessel.
