Recent measurements designed to measure neutral-beam species by nuclear reaction analysis are reported. The detection system and several experiments intended to improve resolution and reduce noise are described. Results obtained at the LBL neutral-beam engineering test facility are discussed and compared with the predictions of optical Doppler-shift spectroscopy.
Three possibilities for making Li/sup -/ ions have been considered: electron capture in a suitable gas or vapor, extraction from a lithium plasma, and production on a low work function surface in a plasma. The only quantitative results, so far, have been for electron capture, with the highest yield being about 5% for Li/sup +/ in Cs vapor at 5 keV. Of the other two methods, Leung has seen some Li/sup -/ produced in the volume of a plasma, and we now report the observation of Li/sup -/ from a surface in a He-Li plasma.
Equilibrium charge-state fractions of 3.3-39 keV deuterium atoms and ions in magnesium vapor are reported. The maximum D− yield is 6.2% at low energies.
