IONIZATION CHAMBER Russian patent published in 2005 - IPC

FIELD: testing of electro-physical characteristics of gas media put under influence of ionizing radiation.

SUBSTANCE: chamber has case filled with gas and provided with window for ionizing radiation. Three electrodes are disposed in the case; all the electrodes are insulated from each other and put alternatively to have spaces. Two of three electrodes are collecting ones and they have zero potential and the third electrode is high-voltage electrode. There are several groups of collecting and high-voltage electrodes disposed inside the case. The electrodes are made in form of disks in such a manner that two groups of electrodes being closest to each other have one common collecting electrode. Each group of electrodes has group of transmitting lines connected correspondingly. High-voltage conductors of transmission lines of each group are connected with high-voltage electrode, and zero potential conductors are connected with adjacent collecting electrodes. Free ends of all transmission lines are connected with collector. Ratio of n=(M-1d)/(120 l)ρ and condition of n<=πd/h+l are satisfied, where n is number of transmission lines, M is number of electrodes, d is diameter of electrode, l is distance between adjacent electrodes, h i s thickness of electrode, ρ is wave resistance of single transmission line.

EFFECT: increased sensitivity of ionization chamber.
