Basic detection property of an array-type CdTe detector for BNCT-SPECT - Measurement and analysis of anti-coincidence events

In this study, we produced an array detector with two CdTe elements to test the basic detection property for anti-coincidence events. Our investigation confirmed that the detector offers an improved S/N ratio by the anti-coincidence detection. We also proposed an estimation method using the MCNP5 to analyze coincidence events in the detector.
