NUMERICAL-SOLUTIONS OF DIFFERENTIAL-EQUATIONS OF A CYLINDRICAL IONIZATION-CHAMBER

The differential equations of the cylindrical ionization chamber fille d with air have been solved numerically for different ratios of the ou ter and inner electrode for both polarities of the voltage supply. The obtained distributions of the electric field strength inside the cham ber confirm the analysis of Thomson and Thomson and the calculations m ade by Mie. The calculated collection efficiencies are in good agreeme nt with the results of the calculation of Sprinkle and Tate, and with the experimental data of Moriuchi et al.
