Title: Improvements in or relating to direct reading beta ray comparator
IPC: G01R23/09
Filed: 1963-08-23
Abstract: 1,023,068. Beta-particle thickness measurement. UNIT PROCESS ASSEMBLIES Inc. Aug. 23, 1963 [Aug. 24, 1962], No. 33395/63. Heading G1A. A beta-ray backscatter thickness measuring instrument of the integrating type is so arranged that sample thickness can be read off directly from the scale of the indicator. The instrument is intended for the measurement of the thickness of the coating of a given material on a known base and in an instrument for such a purpose a radio-active beta source 10 is arranged opposite a target defining aperture in a workpiece support 12. When a coated sample 16 is placed over the aperture back-scattered beta radiation falls on geiger tube 18 and the resulting pulses are fed through cathode follower 20 to trigger monostable multivibrator 22. The multivibrator delivers pulses of standard voltage and length to integrator 26 where they are integrated over a time period determined by timer 28 and the potential across the integrating capacitor 30 applied to valve voltmeter 34 for measurement. The voltmeter circuits are provided with two controls 40 and 44 the first of which varies the resistance in the meter circuit and the second the reference potential. The meter is provided with an auxiliary scale plate 120. A number of these plates capable of being interchangeably mounted on posts 124 can be pre-prepared for different coating and base materials. Prior to making measurements the appropriate auxiliary plate 120 is selected, a sample of the base material placed on plate 12 and a reading taken. This reading is then adjusted to scale zero by means of control 44. Next a standard having a known coating thickness is placed in position and the resulting reading brought to the correct thickness indication by means of control 40. The instrument is then ready for the direct reading of unknown coating thicknesses.
