摘要：
The position sensitivity of two large volume (1" x 1" and 3" x 3") LaBr3:Ce crystals has been measured using collimated beams of 662 keV gamma-rays. The crystals have been coupled to a Position Sensitive Photo Multiplier Tube (PSPMT) and/or shielded phototube. The results indicate that, in the case of 662 keV gamma-rays, both crystals should allow identification of the the position of the gamma-ray first interaction with a 1-2 cm resolution. Similar tests have been done in the past using 140 keV gamma-rays and no sensitivity was found. Using GEANT4 simulations we confirmed these results.
