Problems solved by technology
[0010] As mentioned above, in order to connect the photomultiplier tube with the scintillator, the fixing plate is fixed to the scintillator by the screw 4, so that when the screw is inserted into the scintillator, as Figure 3a , 3b As shown, a crack occurs in the scintillator and a hole is formed by the screw inserted inside the scintillator, so that the light generated by the ray in the scintillator cannot be transmitted to the photomultiplier tube due to the interface between the crack and the screw hole. phenomenon, so that the light generated by the radiation cannot be accurately measured, and thus there is a problem that the measurement error of the radiation is enlarged according to the mounting structure in which the fixing plate on which the photomultiplier tube is mounted is fixed to the scintillator by a screw.

Embodiment Construction
[0033] Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.
[0034] Such as Figure 4 As shown, the structure of installing photomultiplier tubes in the scintillator of the present invention includes: photomultiplier tubes 10; clamps 20 as a fixed unit, and the bracket 25 of the cylindrical part is integrated with the front part 21, so that the above-mentioned photomultiplier tubes The contact state is maintained with respect to the scintillator, and a hole is formed on the front part 21 formed with the bracket, and the upper fixing part and the lower fixing part 22 are separated in a "匚" shape; and the scintillator panel 30, the upper fixing part of the above-mentioned clamp 20 And the lower fixing part 22 is sandwiched between the upper surface and the bottom surface. In the illustrated embodiment the above-mentioned support 25 is shown as a cylindrical part, but could also be rectangular in shape. Alternativel...

The present invention relates to a structure for mounting a photomultiplier tube (PMT) to a scintillator, which is provided with a fixing means for fixing, to a scintillator panel (30) for generatingvisible light by means of radiation collision, a PMT (10)for detecting the visible light, wherein the fixing means comprises a clamp (20) on a front surface part (21) of which a holder (25) for keeping the PMT (10) in contact with the scintillator panel is provided; and fixes the clamp (20) with respect to the top surface and the bottom surface of the scintillator panel (30). Accordingly, the present invention allows the PMT to be easily mounted without damaging the scintillator panel and consequently enables more accurate radiation detection without any light loss which used to occur when mounting a PMT due to a crack in a scintillator panel and a screw inserted into the crack.
Description
technical field [0001] The present invention relates to a photomultiplier tube mounting structure for connecting a photomultiplier tube (PMT: Photomultiplier tube) to a scintillator, and more particularly, to a photomultiplier tube mounting structure having an improved structure for connecting a photomultiplier tube without damaging a scintillator panel . Background technique [0002] Generally, the radiation detection device has a photomultiplier tube for amplifying the flash light generated by the collision of the high-energy particles of the radiation emitted by the object to be detected and the scintillator, so that the radiation emitted by the object to be detected collides with the scintillator The scintillation generated by the time is converted into an electrical signal to measure the number and intensity of the rays. [0003] In a broad sense, rays include not only X-rays, radioactive isotopes, and spacecraft ionizing rays that cause harm to the human body due to i...
