PURPOSE:To increase the strength of a radiation detector charged with a high pressure gas by preparing the window of the detector by stacking a plural number of resin plates in such a manner as to make carbon fibers of slice direction perpendicular to those of channel direction. CONSTITUTION:The window section 13a of a case 13 closed with a lid 14 has a window 15 consisting of a carbon fiber reinforced resin and the case 13 is charged with a detector element and a high pressure gas, thereby constituting a radiation detector. The window 15 is formed by stacking a plural number of plates (15A-15L) each consisting of carbon fibers orienting in one direction and impregnated with a resin. It is formed, for example, by stacking two resin plates made of carbon fibers orienting in 0 deg. direction, one resin plate made of carbon fibers orienting in 90 deg. direction and two resin plates made of carbon fibers orienting at 0 deg. direction in that order. As a result, a high density resolution is achieved by reducing the amount of X-ray absorption. In addition, it is possible to obtain a radiation detector which can be safely used by equalizing its strength in 0 deg. direction and its strength in 90 deg. direction. |
