The gas proportional scintillation counter / microstrip gas chamber hybrid detector
The gas proportional scintillation counter/microstrip gas chamber (GPSC/MSGC) hybrid detector for X-ray spectrometry is described. The detector uses a CsI-coated microstrip plate placed in direct contact with the gas-filling as the photosensor readout for the GPSC scintillation substituting for the photomultiplier tube (PMT). Usable photosensor maximum gain is limited by optical positive feedba...
متن کاملEffect of gas composition on CMS Cathode Strip Chamber performance
Cathode strip chambers (CSCs) are multiwire proportional counters that will be used as muon detectors in the Compact Muon Solenoid (CMS) experiment at the European Center for Nuclear Research (CERN). The composition of the gas inside the chamber influences important chamber parameters, such as gas gain and operational voltage range. Differences in these parameters were examined under variations...
متن کاملEffects of Outgassing from Some Materials on Gas Chamber Ageing
Several different materials that might be used for assembling Micro-strip gas chambers (MSGCs) for high luminosity experiments were tested by measuring the gain of an irradiated wire counter when each sample was put into contact with the gas upstream of the detector. The results show a fast effect on the gain of the counter for some of the materials tested, whereas others, like Stesalit, Vectra...
متن کاملAnterior chamber gas bubbles in open globe injury.
We present a case of a 40-year-old soldier who was in close proximity to the detonation of an improvised explosive device (IED). Bubbles of gas were visible within the anterior chamber of his left eye. The authors propose that intraocular gas, present acutely after trauma, is diagnostic of open globe injury and is of particular importance in remote military environments.
متن کاملDevelopment of MicroStrip Gaseous Chamber for Realtime X-ray Imaging Detector
The MicroStrip Gaseous Chamber (MSGC) was proposed in 1988 [1] as a new type of proportional gaseous detector providing an excellent position resolution. A very fine pitch (<200μm) of signal lines, which could be realized by printing several hundred of strips on a substrate using the Multi-Chip Module technology [2, 3],makes possible to satisfy almost all requirements for X-ray position detecto...
