Holberg,Steven B. Howell,Carole Jordan,Jeffrey L. Linsky,Sarah A. Matthews,Edward M. Sion,Klaus Werner +28 more
TL;DR: APEX as discussed by the authors is a Small Explorer (SMEX) satellite that will investigate the density, temperature, composition, magnetic field, structure, and dynamics of hot astrophysical plasmas.
Proceedings ArticleDOI
Highly curved microchannel plates
Oswald H. W. Siegmund,Scott L. Cully,Geoffrey A. Gaines,William C. Priedhorsky,Jeffrey J. Bloch,John K. Warren +5 more
TL;DR: In this paper, several spherically curved microchannel plate (MCP) stack configurations were studied as part of an ongoing astrophysical detector development program, and as part the development of the ALEXIS satellite payload.

The Next Generation of Photo-Detectors for Particle Astrophysics
Robert Wagner,Karen Byrum,M. C. Sanchez,Alexandre Vaniachine,Oswald H. W. Siegmund,N. Otte,Erik Ramberg,J. Hall,J. H. Buckley +8 more
TL;DR: In this paper, the authors advocate support of research aimed at developing alternatives to the photomultiplier tube for photon detection in large astroparticle experiments such as gamma-ray and neutrino astronomy, and direct dark matter detectors.
Proceedings ArticleDOI
High resolution, two-dimensional imaging, microchannel plate detector for use on a sounding rocket experiment
Brett C. Bush,Daniel M. Cotton,Oswald H. W. Siegmund,Supriya Chakrabarti,W. M. Harris,John Clarke +5 more
TL;DR: In this article, a high-resolution microchannel plate (MCP) imaging detector was used for measurements of Doppler-shifted hydrogen Lyman-alpha line emission from Jupiter and the interplanetary medium.
Proceedings ArticleDOI
Cross-strip anodes for high-rate single-photon imaging
L.C. Stonehill,Joanna S. Salacka,Israel J. Owens,Michael W. Rabin,R. Shirey,David C. Thompson,Oswald H. W. Siegmund,Anton S. Tremsini,John V. Vallerga +8 more
TL;DR: In this article, the authors describe measurements designed to understand the maximum possible event rates that such detectors are capable of handling, and present analysis algorithms and results on their measured ability to resolve events spatially and temporally as the event rate is increased.
