X-ray and Gamma-ray Detectors

Invited Talk

High-resolution gamma-ray detectors based on high-purity germanium (HPGe) are one of the key workhorses of experimental nuclear science.The technical developments of such detectors have been dramatic in recent years, from the emergence of large- volume high-granularity electrically segmented HPGe detectors to position sensitivity using pulse-shape analysis and the novel technique of...

Contributed Talk

A micropattern gaseous detector has been designed for the CERN Axion Search experiment CAST, based on the Micromegas technology. The twodimensional readout, with XY strip structure, allows for sufficient spatial sensitivity and the low natural radioactivity materials used for its construction meet the experiment demands for low background. The detector is operated with an...

X-ray and Gamma-ray Detectors

Contributed Talk

In the last few years several groups and companies tried to develop mammographic scanners based on GaAs, Si solid -state detectors or high -pressure Xe gaseous detectors [1-3]. The main advantages of the scanner system are the simplicity of the design (1D detector) and the readout electronics and hence a low cost. We have developed and successfully tested an innovative approach in...

90. Investigation of Optimal Compton-Suppression Schemes for the TIGRESS HPGe Detector Array

X-ray and Gamma-ray Detectors

Contributed Talk

The TRIUMF-ISAC Gamma-Ray Escape-Suppressed Spectrometer (TIGRESS) is a new gamma-ray detector array being developed in order to take advantage of the radioactive ion beams to be delivered by the new ISAC-II facility at TRIUMPH. When complete, TIGRESS will consist of twelve large-volume 32-fold segmented HPGe clover detectors, fitted with 20-fold segmented Compton-suppression...

67. High Energy Resolution 4 cm wide Double-sided Silicon Strip Detectors for Semiconductor Compton Telescope

X-ray and Gamma-ray Detectors

Contributed Talk

Large area imaging spectrometer with good energy resolution based on double-sided Si strip detector (DSSD) is a key technology for a new generation of Gamma-ray astronomy. It is well suited as the scatterer detector of semiconductor Compton telescopes (SCTs) working at sub-MeV to MeV band. High energy resolution is of particular importance because it ensures better angular resolution...
