Proceedings ArticleDOI
Conceptual design for a deformable mirror for use with X-ray sources
Michael Hart,Johanan L. Codona,Robert Codona,S. Mark Ammons,Bruce Macintosh,Thomas McCarville,T. Pardini,Michael J. Pivovaroff,Lisa Poyneer +8 more
TL;DR: In this article, a deformable mirror (DM) was proposed for high-energy beams of X-rays used in studies of molecular structure. But the optical surface is not sufficiently stable and the authors describe the conceptual design for a new DM that addresses the requirements of this application.
Journal ArticleDOI
The Central X-Ray Point Source in Cassiopeia A
TL;DR: In this paper, Chandra/ACIS spectral and timing data were analyzed for the Cas A point source and it was shown that the spectral properties are consistent with a young Crab-like pulsar, but are inconsistent with the properties of the anomalous X-ray pulsars.
Proceedings ArticleDOI
Multi-material decomposition using low-current X-ray and a photon-counting CZT detector
Sangtaek Kim,Andrew M. Hernandez,Fares Alhassen,Michael J. Pivovaroff,Hyo-Min Cho,Robert G. Gould,Youngho Seo +6 more
TL;DR: The photon-counting CZT-based x-ray imaging system was able to distinguish between the materials, demonstrating its capability as a radiation-spectroscopic decomposition system.
Proceedings ArticleDOI
Adaptive x-ray optics at Lawrence Livermore
TL;DR: Lawrence Livermore's adaptive x-ray optics program is building a 45-actuator, 45-cm long, xray DM, as well as analyzing WFS and DM designs with use of a new wave optics simulation as discussed by the authors.
