Scintillator device
A detector includes a scintillator crystal having a front face and a rear face, a backplate disposed proximal to the rear face of the scintillator crystal, and a biasing member disposed proximal to the backplate and applying a biasing force to the backplate. In turn, the backplate applies a biasing force to the scintillator crystal in a direction toward the front face. The biasing member comprises a single-turn, round-section wire wave spring.
