Front-end electronics for high rate, position sensitive neutron detectors
Advanced neutron detectors for experiments at new spallation sources will require greater counting rate capabilities than previously attainable. This necessitates careful design of both detector and readout electronics. As part of a new instrument for protein crystallography at LANSCE, we are constructing a detector whose concept was described previously (IEEE Trans. Nucl. Sci. NS-46 (1999) 191...
متن کاملDetectors for Sensitive Detection: HyD
This article discusses detectors (more precisely: sensors), that are employed in single point, i.e. true confocal scanning microscopes. The sensors in such systems are usually photomultiplier tubes. Also, the silicon pendants of PMTs are used for particular applications, especially single-molecule measurements. A new development has led to chimeric devices called hybrid detector (HyD) which uni...
متن کاملElectron emission channeling with position-sensitive detectors
Electron emission channeling allows direct lattice location studies of low doses of radioactive atoms implanted in single crystals. For that purpose the anisotropic emission yield of conversion electrons from the crystal surface is measured, most conveniently by use of position-sensitive detectors. We discuss characteristic features of this method, including quantitative data analysis procedure...
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 کاملPosition Sensitive Germanium Detectors for the Advanced Compton Telescope
The nuclear line region of the gamma ray spectrum remains one of the most challenging and elusive goals of high energy astrophysics. The scientific objectives are well defined, but require well over a factor of 10 increase in sensitivity compared to present day instruments to be achieved. The most promising approach to achieve this sensitivity and a broad range of scientific objectives is offer...
