摘要:
The X‐ray Large Array (XLA) was a concept for a very large area array of proportional counters attached to the Space Station, as the station concept existed in the 1980s and into the early 1990s. It was nominally 100 m2of proportional counters for 0.25–25 keV which was (optionally) supplemented by a coded aperture telescope of area 1–2 m2. Although it never flew, it underwent a pre‐Phase A study at NASA‐MSFC and was discussed at many scientific conferences. The purpose of this presentation is to review lessons learned from the XLA experience, both good and bad. It reviews the scientific rationale and engineering issues in achieving and operating very large X‐ray collecting apertures in space, with updates on those issues in the light of later developments. © 2004 American Institute of Physics

摘要:
A moderate sized mission to use bright X‐ray sources as physics labs is described. A combination of microchannel plate optics and a 32×32 pixel microcalorimeter would allow the successor to theRossi XTEto explore new domains of spectroscopic timing in a MIDEX class mission. With ∼10 times the area and ∼100 times the spectral resolution of the PCA (and 10 times that of silicon detectors) such a mission would be able to explore spectral line shifts in magnetars, neutron stars and black holes. Adding a polarimeter would create a powerful and unique capability. Such a mission would make numerous tests of basic physics, both quantum electrodynamics/chromodynamics (QED/QCD) and general relativity. © 2004 American Institute of Physics
