Optimization of virtual Frisch-grid CdZnTe detector designs for imaging and spectroscopy of gamma rays
In the past, various virtual Frisch-grid designs have been proposed for cadmium zinc telluride (CZT) and other compound semiconductor detectors. These include three-terminal, semi-spherical, CAPture, Frisch-ring, capacitive Frisch-grid and pixel devices (along with their modifications). Among them, the Frisch-grid design employing a noncontacting ring extended over the entire side surfaces of p...
متن کاملCdZnTe Frisch collar detectors for g-ray spectroscopy
Low-energy g-ray spectra were collected from Am, Co, Ba, Au, Cs and U using a 3.4 3.4 5.7mm CdZnTe detector utilizing an insulated Frisch ring. The CdZnTe detector was fabricated from a single crystal and a copper shim was used as the Frisch collar. Room-temperature energy resolution of 1.45% full-width half-maximum (FWHM) was obtained for Cs at 661.7 keV without electronic correction. The dete...
متن کاملInstrumentation for Gamma-Ray Spectroscopy
The subject of ttis chapter is the function and operation of the components of a gamma-ray spectroscopy system. In Chapter 3 it was shown that the output pulse amplitude from most gamma-ray detectors is proportional to the energy deposited by the gamma ray. The pulse-height spectrum from such a detector contains a series of full-energy peaks superimposed on a continuous Compton background. Alth...
متن کاملCharge Collection Characteristics of Frisch Collar CdZnTe Gamma Ray Spectrometers
A collimated Au source was used to determine the charge collection efficiency (CCE) at several locations along the length of a 3.4 x 3.4 x 5.5 mm CdZnTe bar detector both in planar configuration and with Frisch collars of varying length. For each configuration, a 0.50 mm long region spanning the width of the device was irradiated with 411 keV gamma rays produced by a neutron activated gold foil...
متن کاملCdZnTe Gamma Ray Spectrometer for Orbital Gamma Ray Spectroscopy
We present the design and analysis of a new gamma ray spectrometer for planetary science that uses an array of CdZnTe detectors to achieve the detection efficiency needed for orbital measurements. The use of CdZnTe will provide significantly improved pulse height resolution relative to scintillation-based detectors, with commensurate improvement in the accuracy of elemental abundances determine...
