Hard X-ray polarimetry with Caliste, a high performance CdTe based imaging spectrometer [PDF]
, 2015 Since the initial exploration of soft gamma-ray sky in the 60's, high-energy celestial sources have been mainly characterized through imaging, spectroscopy and timing analysis. Despite tremendous progress in the field, the radiation mechanisms at work in

Performance-limiting Defects in CdZnTe Detectors [PDF]
2006 IEEE Nuclear Science Symposium Conference Record, 2006 We studied the effects of small, < 20 mum, Te inclusions on the energy resolution of CdZnTe gamma-ray detectors using a highly collimated X-ray beam and gamma-rays, and modeled them via a simplified geometrical approach. Previous reports demonstrated that Te inclusions of about a few microns in diameter degraded the charge-transport properties and ...

An alternative search for the electron capture of Te-123
, 2002 A search for the electron capture of Te-123 has been performed using CdZnTe detectors. After a measuring time of 195 h no signal could be found resulting in a lower half-life limt of $T_{1/2} > 3.2 \cdot 10^{16}$ yrs (95 % CL) for this process.

Performance of three-photon PET imaging: Monte Carlo simulations
, 2005 We have recently introduced the idea of making use of three-photon positron annihilations in positron emission tomography. In this paper the basic characteristics of the three-gamma imaging in PET are studied by means of Monte Carlo simulations and ...
