Abstract: The scientific objectives and future requirements of high energy x-ray astronomy are discussed and concepts for imaging instruments based on CdZnTe detectors and coded masks are reviewed. An instrument concept based on CdZnTe strip detectors, HEXIS, is described in detail. Technical requirements for large area CdZnTe strip detectors are discussed and recent work at UCSD and WU on the capabilities of CdZnTe strip detectors is described in detail. Studies with small, approximately 50 micron beams demonstrate that crossed strip detectors have good properties for both spatial and spectral measurements.

- 19 Oct 1999
TL;DR: In this article, a model of charge drift in the detectors and charge induction on the electrodes has been developed to better understand these types of detectors and improve their design, which is very promising for large area detector arrays in coded mask imagers and small-area focal plane detectors for focusing x-ray telescopes.

TL;DR: In this paper, the performance measurements of a sub-millimeter resolution CdZnTe strip detector developed as a prototype for astronomical instruments were reported. But they were performed at several energies and the room-temperature energy resolution was 5:1.
Analysis of data from coded-mask telescopes by maximum likelihood
G. K. Skinner,M.R. Nottingham +1 more
TL;DR: In this article, a new method, maximum likelihood fitting (MALF), was proposed for the analysis of data from non-cyclic coded mask telescopes, which avoids artifacts due to strong sources and handles in an optimum way data affected by small-number statistics, by partial coding and by real systems such as finite detector depth and obscurations of parts of the detector.

Evidence for x Rays From Sources Outside the Solar System
TL;DR: In this article, data from an Aerobee rocket carrying three large-area geiger counters have revealed a considerable flux of radiation in the night sky and the bulk of the radiation is soft x rays from sources outside the solar system.
