SCINTILLATION DETECTOR WITH SLEEVED CRYSTAL BOOT

摘要

A scintillation detector (10) includes a scintillation crystal (14) and-a shock absorbing member (76) circumscribing the crystal (14). A sleeve (98) circumscribes the shock absorbing member (76) which, in turn, is circumscribed by a housing (12). The sleeve (98) provides for substantial controlled radial loading on the crystal (14). A method of manufacturing the detector (10) includes placing the crystal (14) and shock absorbing member (76) into the sleeve (98), compressing the sleeve 98 and inserting the compressed sleeve (98) into the housing (12) such that the sleeve (98) substantially maintains its compression. The radial stiffness causes vibration induced counts to occur at an excitation frequency which is above the operational bandwidth of the radiation measurements, thereby excluding vibration induced counts for radiation measurements.
