[A heterogeneous air-filled ionization chamber without external power supply]

Possibility of the use of heterogeneous ionization chambers with air-filled interelectrode space for X-ray detection is discussed. Qualitative analysis of the process of generation of ionization current in the heterogeneous chamber without external power supply is performed. Experimental data presented in this work show that ionization chambers with triple heterogeneous structure provide high operating characteristics when connected in active integrator and current-to-voltage converter circuits (especially in the case of differential connection circuit).
