SCINTILLATION CRYSTALS HAVING FEATURES ON A SIDE, RADIATION DETECTION APPARATUSES INCLUDING SUCH SCINTILLATION CRYSTALS, AND PROCESSES OF FORMING THE SAME

摘要

A scintillation crystal capable of emitting scintillation light can have a main body and a feature extending from the main body along a side of the scintillation crystal. The feature can have a dimension that is no greater than 2.5 times a wavelength of the scintillating light. In an embodiment, the feature and the main body can have substantially the same composition, and in a further embodiment the scintillation crystal can be interface free between the feature and the main body. The feature can be formed along the side of the scintillation crystal by removing portions of the scintillation crystal. In particular, the feature can be formed by abrading a surface of the scintillation crystal with an abrasive material.
