Low Power X-Ray Photon Resolving Imaging Array, Phase I

Completed Technology Project

Project Introduction

Low Power X-Ray Photon Resolving Imaging Array, Phase I
Instruments employing X-ray detection are countless, in different sectors from medicine to industry and from basic to applied science. Given this importance, and despite existing technologies, there is still need for X-ray detection with increased system performance. The solid-state detector array is the primary technology to implement the current generation of space borne high-energy astronomy missions that are managed by NASA in partnership with the international community. Readout integrated circuitry (ROIC) specifically designed for photon resolving X-ray detection with solid-state detectors will create a new generation of high-performance X-ray imaging sensors. AC coupled detector input circuitry, similar to that used by Black Forest Engineering (BFE) for laser detection and ranging (LADAR), is ideally suited to NASA X-ray astronomy imaging system requirements. BFE proposes on Phase I to design, process and test detector input circuitry to meet a wide range of NASA X-ray imaging applications. The input circuit, when implemented into an ASIC X-ray imaging ROIC, manufactured and integrated with a solid-state detector array on Phase II, will provide single photon sensitivity, accurate X-ray energy determination, X-ray event time stamping, low power dissipation and ambient temperature operation.
