Abstract

1,148,440. Ionization chambers. MICROTEK INSTRUMENTS CORP. 17 Oct., 1966 [18 Oct., 1965], No. 46358/66. Heading H1D. A radio-active source 86 including Ni<SP>63</SP> is used to promote ionization in a detector cell. A foil consisting entirely of Ni<SP>63</SP> may be used, or a layer of Ni<SP>63</SP> may be plated on a backing foil of gold, nickel, platinum or stainless steel or may be plated on an an electrode, preferably the cathode, of the cell. The cell shown comprises a cathode 80, insulating spacer 84, and conductive wafer 85 through which the anode 81 is adjustably screwed, forming a chamber 83 provided with a gas inlet 87 and outlet 90. Connection to the cathode and anode is by way of rods 96 and 98 supported by insulators 100 and 101 in sockets 97 and 99. The chamber and surrounding insulators 91, 92 are enclosed in members 93, 94, 95 forming a cylindrical body. A heater cartridge and temperature limit switch are provided in cylindrical recesses (not shown) in body member 93 to heat the cell to temperatures up to 500‹ C. The metal parts are preferably of stainless steel and the insulators of ceramic, preferably boron nitride. Simple cell constructions having parallel plane, cylindrical, and pin and cup electrode geometrics are described with reference to Figs. 1 to 4 (not shown). The gas filling may be argon.
