“…Therefore usual cone type algorithms are modified in different ways to take into account this background. In [25] the possibility of jet recognition in central PbPb collision in CMS detector with the help of modified UA1-algorithm was studied. It is shown that for jets with E T > 50 GeV the recognition efficiency is close to 100 %.…”

The event-by-event analysis of multiparticle production in high energy hadron and nuclei collisions can be performed using the discrete wavelet transformation. The ring-like and jet-like structures in two-dimensional angular histograms are well extracted by wavelet analysis. For the first time the method is applied to the jet-like events with background simulated by event generators, which are developed to describe nucleus-nucleus collisions at LHC energies. The jet positions are located quite well by the discrete wavelet transformation of angular particle distribution even in presence of strong background.

“…This design results in a very compact detector with reduced space-charge effects, high rate capabilities and stable gains in the 10-10 range, in addition to inherent spatial sensitivity. MSGCs have found success in diverse fields such as high-energy physics, X-ray astronomy, medicine and EDXRS applications [11][12][13][14][15].…”

A P10-filled microstrip gas chamber (MSGC) is used to replace the conventional photomultiplier tube (PMT) as the photosensor for a gas proportional scintillation counter (GPSC). The vacuum ultraviolet (VUV) scintillation light produced in the xenon-filled GPSC is transmitted through a 1 mm thick high-purity quartz window to the MSGC where it is converted to photoelectrons by a CsI photocathode deposited directly onto the surface of a microstrip plate (MSP). These photoelectrons are afterwards multiplied near the microstrip plate anodes with a charge gain of about 10. The energy resolution achieved for 5.9 keV X-rays is 11.5% which, while not yet as good as the 8% figure for standard GPSC (instrumented with a PMT), is already better than the energy resolution obtained for standard proportional counters. Experimental results are presented and discussed. With this design a compact GPSC is obtained which has the further advantage of being much less sensitive to magnetic fields than PMT-based GPSCs.

The characteristics of a one-atmosphere xenon gas proportional scintillation counter (GPSC) instrumented with a novel photosensor are reported. A microstrip gas chamber (MSGC) with a CsI photocathode deposited directly onto its electrode surface is used in place of the standard photomultiplier tube assembly to record the scintillation light from xenon. The microstrip electrodes also function as the GPSC second scintillation grid. The combination results in a simple and compact device that demonstrates the linear response characteristics of the scintillation process in xenon.
