Resumo

The first steps towards a Monte Carlo simulation method for energy and position corrections in a gas scintillator detector are presented. Recent developments on gas avalanche detectors based on microstructures operating a thigh pressure allow fair detection efficiency for hard X- and gamma-rays. A hybrid system combining an assisted scintillation in a high pressure xenon gas medium and two UV photosensors based on microstructures operating face to face, having the xenon medium sandwiched between them, is under investigation. One of the actual studies is the simulation of the position and amplitude response of the detector and their correction obtained by mapping the detector response. This method can also be applied to solid scintilators.
