Scientific Reviews: Microstrip Detectors with ¹⁵⁷Gd Converters

Abstract

In the current (2004-2008) Joint Research Activity DETNI (Detectors for Neutron Instrumentation) in the EU Integrated Infrastructure Initiative for Neutron Scattering and Muon Spectroscopy (NMI3), three detector types and a common ASIC and data acquisition board family are being developed. Two of these detector types, i.e., silicon microstrip (Si-MSD) and hybrid microstrip gas chamber (MSGC) detectors, are described in this article, both using thin ¹⁵⁷Gd converters and aiming at two-dimensional position resolutions of 50-100 μm FWHM, pulse-height readout for center-of-gravity calculation and background suppression, time-of-flight (TOF) resolution <<1 μs, and a counting rate capacity of 10⁸ events/s per detector module with single event counting. The third detector type is the CASCADE detector discussed in the another article.
