H– and D– sources for fusion, accelerators and other applications
Oral
Pulsed and CW operation of negative ion radio frequency surface plasma source with a solenoidal magnetic field is described. Dependences of a beam current on RF power, extraction voltage, solenoid magnetic field, gas flow are presented. Compact design of RF SPS is presented.
The work was supported in part by US DOE Contract DE-AC05-00OR22725 and by STTR grant, DE-SC0011323.

H– and D– sources for fusion, accelerators and other applications
Oral
Negative ion sources are a key component of neutral beam injection systems. A novel concept for a negative ion source based on existing well tested Hall thrusters (HT) is presented. The thruster has been designed in order to maximize the hydrogen dissociation process so that the atom flux which exits the thruster has an optimized energy to generate negative ions when impinging on a low work...

H– and D– sources for fusion, accelerators and other applications
Oral
Negative ion source based neutral beam injection system is one of the most efficient method of fusion plasma heating. Negative ion source is used instead of positive ions in case of higher power NBIs,due to high neutralization factor in the beam energy range useful for ITER type fusion reactors.To understand the efficiency of negative ion source, negative ion density measurement is a...
