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...
First observations of CN(2-1), HCO$^{+}$(3-2) and C$_{2}$H(3-2) emission lines in the Perseus cluster: constraints on heating mechanisms in the cluster gas

A parochial review is presented concerning the status of our understandingof hot gas regions in the Galaxy and their implications for the overall distributionsof the Galaxy抯 gaseous components. We hav...
Major advances have been made in the past decade in our knowledge of the hotinterstellar gas of our Milky Way galaxy. The Di.use X-ray Spectrometer obtainedspectra in the 0.15?.28 keV range from the G...
