Gamma ray polarimetry using a position sensitive germanium detector
Imaging gamma-ray detectors make sensitive polarimeters in the Compton energy regime by measuring the scatter direction of gamma-rays. The principle is to capitalize on the angular dependence of the Compton scattering cross section to polarized gamma rays and measure the distribution of scatter directions within the detector. This technique is effective in a double-sided germanium detector betw...
متن کاملPosition-sensitive germanium detectors for gamma-ray imaging and spectroscopy
Gamma-ray imaging with position-sensitive germanium detectors offers the advantages of excellent energy resolution, high detection efficiency, and potentially good spatial resolution. The development of the amorphous-semiconductor electrical contact technology for germanium detectors has simplified the production of these position-sensitive detectors and has made possible the use of unique dete...
متن کاملMonte Carlo simulation of the X-ray response of a germanium microstrip detector with energy and position resolution
We present Monte Carlo computer simulations of the X-ray response of a micro-strip germanium detector over the energy range 30}100 keV. The detector consists of a linear array of lithographically de"ned 150 lm wide strips on a high purity monolithic germanium crystal of 6 mm thickness. The simulation code is divided into two parts. We "rst consider a 10 lm wide X-ray beam striking the detector ...
متن کاملX-Ray Imaging with a Silicon Microstrip Detector
A single photon counting X-ray imaging system, with possible applications to dual energy mammography and angiography, is presented. A silicon microstrip detector with 100 mm pitch strips is coupled to RX64 ASICs, each of them including 64 channels of preamplifier, shaper, discriminator and scaler. The system has low noise, good spatial resolution and high counting rate capability. Results on en...
متن کاملMonte Carlo Simulation of a Position Sensitive Gamma Ray Detector
The Monte Carlo method was employed to obtain the response of a position sensitive gamma ray detector. The basic unit consists of a scintillator bar coupled to two photon detectors. Determination of the position of interaction is obtained from the ratio of the light intensity measured at each extremity of the bar. Association of two or more detectors of this type can be used to build a system w...
