Journal ArticleDOI
Gamma-ray mirrors for direct measurement of spent nuclear fuel
TL;DR: In this article, a multilayer grazing-incidence gamma-ray optics was proposed to serve as a notch filter, passing only narrow regions of the overall spectrum to a fully shielded detector that does not view the spent fuel directly.
Journal ArticleDOI
The search for axions
TL;DR: The axion is a light pseudoscalar particle predicted to exist as a consequence of the Peccei-Quinn solution to the strong-CP problem as discussed by the authors.
Proceedings ArticleDOI

TL;DR: In this paper, the authors developed efficient detector screening methods to select and calibrate flight quality, x-ray CCD detectors for the AXAF CCD imaging spectrometer, which can identify which of the greater than 30 flight candidate detectors warrant the expenditure of severely limited time available for calibration.

TL;DR: The International Axion Experiment (IAXO) as discussed by the authors is a helioscope with a sensitivity at least 104 better than CAST phase-I, resulting in sensitivity on gaγ one order of magnitude better.
Proceedings ArticleDOI
Using tritium and x-ray tubes as x-ray calibration sources for the AXAF CCD Imaging Spectrometer
TL;DR: In this article, a windowless radioactive source using the beta spectrum from tritium to fluoresce low-energy x-rays from low Z targets was developed, which is coupled with an additional system based on a stable commercial x-ray tube to produce higher energy X-rays.
