The core principle of segmented detectors like AGATA [1], GRETA [2], that will be used in future for 4π gamma detection arrays, is the application of the concept of pulse shape analysis (PSA). The key ingredient for this analysis is a data base containing pulses for all the interaction points inside the segmented detector. A full 3D scanning of the detectors, which experimentally determines pul...

We present a new concept for c-ray detector arrays. An example, called GRETA (Gamma-Ray Energy Tracking Array), consists of highly segmented HPGe detectors covering 4p solid angle. The new feature is the ability to track the scattering sequence of incident c-rays and in every event, this potentially allows one to measure with high resolution the energy deposited, the location (incident angle) a...

We analyze the effects of electrode size on performance of arrays of semiconductor gamma-ray detectors, especially when there is significant charge trapping. With large electrodes, motions of holes and electrons are of equal importance, but when the positive electrode is segmented into an array of small elements the contributions of holes to the output, and hence the effects of hole trapping, a...

The capabilities of future Germanium (HPGe) detector arrays consisting of large volume segmented crystals like AGATA [1] will depend heavily on the performance of γray tracking. The most crucial component in the whole concept is the pulse shape analysis (PSA). The efficiency of tracking algorithms hinges on the ability of the PSA to reconstruct the interaction locations accurately, especially f...

Modern positron emission tomography (PET) detectors are typically made from 2D modular arrays of scintillation crystals. Their characteristic flood field response (or flood histogram) must be segmented in order to correctly determine the crystal of annihilation photon interaction in the system. Crystal identification information thus generated is also needed for accurate system modeling as well...

The necessity to increase exposure in rare event search experiments by maintaining a low energy threshold and good resolution leads segmented detectors as EDELWEISS (Dark Matter), CUORE (0 $$\nu \beta \beta$$ ) or Ricochet (CENNS) for example. However, the large number of sub-elements can dramatically complexity such detector arrays. In this work we report on our progress towards designing flex...

We are developing two-dimensional 16 × 25 pixel detector arrays of both unstressed and stressed Ge:Ga photoconduc-tive detectors for far-infrared astronomy from SOFIA. The arrays, based on earlier 5 × 5 detector arrays used on the KAO, will be for our new instrument, the Far Infrared Field Imaging Line Spectrometer (FIFI LS). The unstressed Ge:Ga detector array will cover the wavelength range f...
