THE CHARGE EXCHANGE CELL FOR THE NEUTRAL LITHIUM BEAM PROBE ON PULSATOR, W7A AND ASDEX
The charge exchange cell forming a part of the lithium diagnostic beam line on Pulsator, Wendelstein 7a and ASDEX is described. The cell consists of a neutralization tube of 12 cm length attached to a reservoir which supplies the neutralizing medium, either lithium or sodium. To reduce cell losses, operation is on a pulsed basis by means of a valve which seals the reservoir during periods when the beam is not on. Using sodium, neutralization efficiencies for a Li**+ beam vary typically from C.97 % at 20 keV to 57 % at 100 keV.
