Gas Gain Measurements from a Negative Ion TPC X-ray Polarimeter
Gas Gain Measurements Negative TPC X-ray Polarimeter
2011/10/9
Gas-based time projection chambers (TPCs) have been shown to be highly sensitive X-ray polarimeters having excellent quantum efficiency while at the same time achieving large modulation factors. To ob...

2011/9/30
We present an analysis of the atmospheric content of aerosols measured at Observatorio del Roque de los Muchachos (ORM; Canary Islands). Using a laser diode particle counter located at the Telescopio ...
Spectral Measurements of Cyg X-3: A Thermal Source Embedded in Hot Plasma within a Cold Shell
Low mass X-ray binaries X-ray sources Cyg X-3
2009/5/19
The attempts at unified model fitting to explain the spectral
variations in Cyg X-3 suggest equally probable fits with a combination of
an absorbed blackbody and a separately absorbed power law with...
