Volume recombination parameter in ionization chambers

M Boutillon

Show affiliations


The parameter governing the volume recombination in ionization chambers has been measured under conditions which allow strict application of the basic theory. The method consists of measuring the ratio of ionization currents and obtained at two given voltages and as a function of . The value of is derived from a linear extrapolation to zero current. Several pairs of voltages (, ) were used. The value of obtained in this work is with a relative uncertainty of 1.7%. The dependence of on atmospheric conditions has also been investigated.
