原始语种摘要: Abstract(#br)A new approach for lithium drifting in silicon is described where the silicon devices under drift are held at constant temperature and bias at normal air ambient, and the drift process is terminated at the end of an estimated time depending upon the thickness of wafers. A 4-channel lithium drifting unit with electronically controlled oven has been constructed for this purpose. Full details of the fabrication procedure are given. A sizable number of Si(Li) detectors have been fabricated using this approach. The quality of the detectors is tested with 241 Am alphas and conversion electrons from 209 Bi and 137 Cs sources. The detectors are regularly used for nuclear physics experiments at this Centre.
