Scintillator module, scintillator sensor unit, and scintillator module production method
View Patent ↗According to an embodiment, a scintillator module includes a moisture-proof welding layer and a resin case. The moisture-proof welding layer is formed of a material having a welding property and a moisture-proof property, and extends to a side surface of a fiber optic plate to cover, in a sealed state, a scintillator layer and a visible-light reflective layer laminated on the fiber optic plate. The resin case covers the moisture-proof welding layer while being pressed against the side surface of the fiber optic plate.
1. A scintillator module comprising:
a moisture-proof welding layer that:
is formed of a material having a welding property and a moisture-proof property, and extends to a side surface of a fiber optic plate to cover, in a sealed state, a scintillator layer and a visible-light reflective layer laminated on the fiber optic plate; and
a resin case that covers the moisture-proof welding layer while being pressed against the side surface of the fiber optic plate.
2. The scintillator module according to claim 1 , wherein the resin case includes:
a face that opposes the moisture-proof welding layer through the visible-light reflective layer, and
a peripheral wall of a shape conforming to a periphery of the fiber optic plate.
3. The scintillator module according to claim 2 , wherein the resin case opposes and is fitted to the fiber optic plate through the peripheral wall and the moisture-proof welding layer.
4. The scintillator module according to claim 1 , wherein the resin case is formed of a thermoplastic resin with a certain shrinkage ratio or more, so that the resin case, when shrunk, becomes pressed against the moisture-proof welding layer.
5. The scintillator module according to claim 4 , wherein the resin case is formed of a crystalline resin with a shrinkage ratio of 10/1,000% or more.
6. The scintillator module according to claim 1 , wherein the moisture-proof is formed of a butyl-rubber welding material.
7. A scintillator sensor unit comprising:
the scintillator module according to claim 1 ; and
a photodiode array unit that is placed in opposition to the fiber optic plate.
8. A method for manufacturing a scintillator module comprising:
forming a material having a welding property and a moisture-proof property into a moisture-proof welding layer that extends to a side surface of a fiber optic plate to cover, in a sealed state, a scintillator layer and a visible-light reflective layer laminated on the fiber optic plate; and
covering by a resin case, the moisture-proof welding layer while being pressed against the side surface of the fiber optic plate.
