摘要

Gas proportional counter arrays based on the micro-well are an example of a new generation of detectors that exploit narrow anode-cathode gaps, rather than fine anodes, to create gas gain. These are inherently imaging pixel detectors that can be amde very large for reasonable costs. Because of their intrinsic gaina nd room-temperature operation, they can be instrumented at very low power per unit area, making them valuable for a variety of space-flight applications where largearea X-ray imaging or particle tracking is required. We discuss micro-well detectors as focal plane imager for Lobster-ISS, a proposed soft X-ray all-sky monitor, and as electron trackers for the Next Generation High-Energy Gamma Ray mission.
