The GERmanium Detector Array, GERDA, is designed for the search for “neutrinoless double beta decay” (0ν2β) with germanium detectors enriched in 76Ge. An 18-fold segmented prototype detector for GERDA Phase II was exposed to an AmBe neutron source to improve the understanding of neutron induced backgrounds. Neutron interactions with the germanium isotopes themselves and in the surrounding mater...

Geant4 is a toolkit for the simulation of the passage of particles through matter, developed with advanced software engineering techniques. Its application areas include high energy and nuclear physics experiments, space physics, medical physics and radiation background studies.

in this study, a general theoretical model to foresee and calculate the current-voltagecharacteristics in a plateau zone and the associated efficiency of the neutron detector (sensitivity) is presented. this study is to complete the previous studies in this field. the model also considers electric field distortion resulting from the charge collection effect. the characteristics curve is obtaine...

We describe an extension to the Geant4 software package that allows it to be used as a general purpose X-ray tracing package. We demonstrate its use by building a model of the X-ray optics of the XMM-Newton, calculating its effective area, and comparing the results with the published calibration curves.
