Next: Front Illumination Up: Detection Efficiency Previous: Detection Efficiency . Work at Westinghouse [Peckerar et al] first demonstrated the possibility for enhancing X-ray detection efficiency by utilising deep depletion layers. The depth of a depletion layer varies as . where is the depleting potential, and is the acceptor concentration. The applied potential is limited by the breakdown voltage of the MOS structure, and hence the use of high resistivity silicon (low ) is required. ...

ARCSAT ID NUMBER: AS07 DESCRIPTIVE TITLE: Census of Variable stars in the UMi dwarf spheroidal galaxy. ... BRIEF SCIENCE JUSTIFICATION: The classical dwarf spheroidal galaxy Ursa Minor contains a large number of variable stars, particularly of the RR Lyrae and anomalous Cepheid types. ... The photometry will be done with DAOPHOT, much like the Nemec study, and the analysis of the RR Lyrae population will be similar to the work done with the Draco dwarf spheroidal galaxy (Kinemuchi et al. ...
. Comment on J0431+2037 . A Gigahertz Peaked Spectrum (GPS) galaxy with complex radio structure on the scale of 10 to 100 mas (combined EVN+MERLIN data at 1.6 GHz, Dallacasa et al. 1995). Our image is consistent with the center-southern features of Dallacasa et al. (1995). The northern feature, ~180 mas N-NW from the field center, outside the boundary of the displayed image, can barely be seen in our data. VLBApls home page . Last modified: 16 Oct 2000
