A telescope consisting of three silicon microstrip detectors has been tested in a. high energy positron beam at SLAC. Each detector has strips with 25 micron pitch and is read out by two 128-channel NMOS integrated circuits (“Microplex”). Results on the signal-to-noise ratio, spatial resolution, and two-track separation are given. Presented at the Fourth European Symposium on Semiconductor Dete...

Electronics are a key component of all modern detector systems. Although experiments and their associated electronics can take very different forms, the same basic principles of the electronic readout and optimization of signal-tonoise ratio apply to all. This chapter provides a summary of front-end electronics components and discusses signal processing with an emphasis on electronic noise. Bec...

This pathway describes the development of soft gamma-ray/hard x-ray detector arrays at NASA’s Goddard Space Flight Center (GSFC, or Goddard), through a collaboration between the gamma-ray spectroscopy group and the detector branch. The Cadmium Zinc Telluride (CdZnTe, or CZT) detectors which resulted from this decade-long development were first flown on the wildly successful SWIFT mission in 200...

We have described an approach for miniaturizing spectroscopic devices by using the advantages presented by elastomeric based microfluidics and semiconductor detectors/emitters. Elastomers allow for both absorption and fluorescent spectroscopy in the visible range to be conducted on small volumes of solution and allow for easy integration with existing detectors such as CMOS imagers, CCD imagers...

A CMOS (complementary metal-oxide semiconductor) flatpanel X-ray detector is a two-dimensional silicon image sensor with a scintillator. We have tested the performance of two types of CMOS detectors in simultaneous small-angle/wideangle X-ray scattering experiments. Both are active-pixel devices that have an amplifier in each pixel. Wide-angle patterns were recorded with the detector just behin...

A new method for measuring the electron mobility, the electron mean free drift time, and their product has been developed for pixelated semiconductor detectors. Using data from a standard calibration measurement, these three quantities are measured and compared against results using other methods. Since the results can be easily obtained, comparisons of many detectors have been completed and sh...

Complementary metal-oxide semiconductor (CMOS)-hybrid arrays have become competitive optical detectors for use in ground- and space-based astronomy. Interpixel capacitance (IPC) is one source of error that appears in most CMOS arrays. In this paper, we use a single-pixel-reset method to model IPC. We combine this IPC model with a model for charge diffusion to estimate the total crosstalk on H4R...
