摘要

Adaptation of a Frisch Grid alpha ionization chamber and its preamplifier to an Argonne-type 256-channel pulse height analyzer for alpha spectroscopy is described. Overall resolution of better than 1% is achieved. Circuit modi¬fications to the commercial preamplifier are given, and a procedure for electro-deposition of thin samples is described.
