Title:
GAS PROPORTIONAL COUNTER TUBE AND PHOTOGRAPHING SYSTEM
Document Type and Number:
Japanese Patent JP3955836
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas proportional counter tube and a photographing system in which impact resistances and handling natures of an electron and an optical multiplication part can be improved and a fine pores can be made uniform, and the uniformity of sensitivity distribution can be improved.
SOLUTION: A photographing type X ray detection device 200 has a photographing system 210 connected to a power supply system 34 and a control system 35. In the photographing system 210, a chamber 23 having a CMOS sensor array is jointed through an FOP2 to the rear stage of a chamber 22 which has a beryllium aperture 21 and is provided with a porous plate 1 having a numerous number of hollow filaments 13 provided side by side.
