Abstract
970,432. Ionization counters. T. ICHINOKAWA. April 2, 1962 [April 22, 1961], No. 12623/62. Heading H1D. A proportional counter for detecting soft, e.g. carbon Kα (44 ) X-rays has an entrance window 4 composed of a thin (0.2-0.5 Á) film of a thermoplastic resin composed of a linear aromatic polyester of carbonic acid. The film may be prepared by dissolving the polyester in methylene chloride and pouring the solution over an inclined glass plate. The tube 1 may be filled with an argon 90%, methane 10%, mixture at 1 atmosphere, and mounted in vacuo. The window may be coated internally with aluminium.
