Numerical solutions of differential equations of a cylindrical ionization chamber
MetadataShow full item record
The differential equations of the cylindrical ionization chamber filled with air have been solved numerically for different ratios of the outer and inner electrode for both polarities of the voltage supply. The obtained distributions of the electric field strength inside the chamber confirm the analysis of Thomson and Thomson and the calculations made by Mie. The calculated collection efficiencies are in good agreement with the results of the calculation of Sprinkle and Tate, and with the experimental data of Moriuchi et al.
