High temporal performance gamma-ray detector Detector conceptCherenkov emission has received attention to improve timing resolution of detectors dedicated to positron emission tomography. Since the Cherenkov photons are promptly emitted within an order of 1 ps, the timing performance of the ...
The newly developed Ge detector segmentation technology together with state-of-the-art digital signal processing allow to define the locations of gamma-ray interaction points as well as the deposited energies in these points. Using this information, it is possible to reconstruct the paths of gamma-...

CdTe radiation detectors have been fabricated in a new M–π–n structure that provides very effective blocking for the leakage current and, as a result, excellent spectral responses are achieved. An iodine-doped n-CdTe layer was grown on the Te-faces of the (1 1 1)-oriented high-resistivi...
Effect of prolonged annealing on the performance of coaxial Ge gamma-ray detectors The effects of prolonged annealing at elevated temperatures have been investigated in a 53cm3 closed-end coaxial high purity germanium detector in the reve... A Owens,S Brandenburg,EJ Buis,... - 《Journal of Ins...
ray astronomy is the same as it is for X-ray astronomy. We've described the basics of these types of detectors on theX-ray Detectorpage. Below we describe three types of detectors used uniquely for gamma-ray astronomy: Compton scattering detectors, pair telescopes, and air Cerenkov detectors...
X-123 represents the culmination of 14 years of X-ray detector development at Amptek. Our philosophy has always been to create small, low power, high performance instruments while keeping them simple to operate. The X-123CdTe exemplifies this philosophy in a single package. Al...
