THE EFFECT OF WALL MATERIAL AND ELECTRODE SPACING ON THE RESPONSE OF A PARALLEL-PLATE IONIZATION CHAMBER (thesis)
Technical Report

OSTI ID:4175407
The Bragg-Gray principle and recently proposed modifications to it are reviewed and compared in some detail. The Bragg-Gray principle relates the energy absorbed in the walls of a small ionization chamber to the energy absorbed in the gas in the cavity, when the chamber is subjected to x or gamma radiation. A cavity ionization charnber is designed and fabricated. The chamber is irradiated with Co/sup 60/ gamma rays, and the resulting ionization current is measured as a function of front wall thickness, wall atomic number, and front and back wall separation. The results of the experiment are compared to the existing theories. (W.L.H.)
