PURPOSE: To obtain a stable high-performance structure by constituting a detector assembly by fixing individual detector modules in a frame with a plurality of threaded tightening members and selectively arranging the modules. CONSTITUTION: A frame 21 is formed by fixing the upper and lower supporting members 12 and 13 of a detector assembly 11 with spacers 16 and 17, etc. During the formation of the frame 21, detector modules 22-27 having nearly same structures are arranged. Each module is constituted of upper and lower insulating members 28 and 29 made of a ceramic material. A void space 33 is provided in each module and an inserting body 34 is fixed in the space 33 with an adhesive 30 and fixed to the frame 21 by means of a tightening member 31. Therefore, a stable high-performance detector assembly can be obtained by conducting preliminary tests on the modules and arranging the modules to appropriate positions in freely releasable states.
