Data from CSCs are used to provide online trigger primitives for the CMS Muon trigger, as well as hits and track segments used for CMS High Level Trigger (HLT) and for offline reconstruction of muon segments. Ward, Emma Imported geometry models such the beam pipe. The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. The chambers have been installed in the detector and commissioning has been completed. The Muon Spectrometer of the ATLAS detector at the LHC is designed to provide high quality stand-alone muon identification, momentum measurement and trigger capabilities with high pseudorapidity coverage. In total, there are about 2.5 million wires, and the overall area covered by the planes is around 6000 m2. Close. 1), it knocks electrons out of the gas molecules and they flock to anode wires, meanwhile positively charged ions move towards cathode strips inducing a charge on them. cathode-strip chambers (CSCs) of the CMS End-cap Muon system [2] provide the high coordinate precision and fast response time needed for effective bunch crossing number identification. Presented are the main design features of the large cathode strip chambers (CSCs) for the CMS endcap muon system as well as the performance results obtained with the first large-scale prototype. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. The anode group numbers increase with increasing radius R.The strip numbers in the wide part (1Ä64) increase with increasing φ, while in the narrow part the readout direction is opposite (1Ä16). When a charged particle passes through a layer of CSC (fig. The CSCs [3] are six-layer, two-coordinate-mea-suring, multiwire-proportional, cathode-strip chambers separated by the iron disks of the flux … Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. The chambers have been installed in the detector and commissioning has been completed. For all the ME1/1 CSCs the layer numbers increase from 1 to 6 going away from the interaction point (IP). 1.3 CSC Principle of Operation The basic construction of a CSC is that of a conventional wire chamber. The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. Measured noise levels are low, with the number of noisy channels well below 1%. Want to know more? Strips, milled on the cathode panels, run radially in the endcap geometry and thus provide a precise measurement of the ϕ-coordinate. Their purpose is to efficiently filter out the background particle, tracking only the muons traversing it with high degree of accuracy. Performance of the CMS cathode strip chambers with cosmic rays Therefore, out of six 3}4 strips and stretched in time over a few time measurements along a muon track in a chamber, samples. proportional cathode-strip chambers separated by theiron disks of the flux return yoke of the CMS magnet. The three detector stations reside in a radial field magnet and must provide 100μm resolution per CSC detector plane to give satisfactory mass resolution for the vector mesons. Each CSC consists of six layers. ME1/1 Cathode Strip Chambers for CMS Experiment 569 are shown. Figure 1. The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. A model has been considered of the Cathode Strip Chamber (CSC) exposed to the muon stream of high intensity (70 Hz/cm2) originating in the crossing point of beams of the LHC collider. They were designed and produced in Dubna. The chambers were then thoroughly retested after shipment to CERN. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. The Cathode Strip Chambers (CSCs) are special multiwire proportional chambers placed in the high region of the Muon Spectrometer, where flux of background particles is highest. The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. The production, installation, and testing of 468 cathode strip chambers for the endcap muon system of the CMS experiment played a critical role in the preparation of the endcap muon system for the final commissioning. Microstrip gas chambers achieve high precision and high rate by emulating the field structure of multiwire chambers using a sequence of alternating anode and cathode strips on an insulating support. The PHENIX Muon Tracker Cathode Strip Chambers (CSC) detector system is now beginning final construction for both of the muon spectrometers. Two CMS production Cathode Strip Chambers were tested for aging effects in the high radiation environment at the Gamma Irradiation Facility at CERN. Close Tracking. The ME1/1 cathode strip chambers are the part of the CMS endcap muon system. Measured noise levels are low, with the number of noisy channels well below 1%. The 3.4×1.2 m 2 six-plane prototype has been reliably operated over one year and the cosmic-ray tests showed that it was capable of detecting muons with ∼80 μm spatial and ∼5 ns time … This paper describes chamber readout electronics and presents the results of the tests with cosmicray muons. Tracks (reco. Common testing procedures and sets of standard equipment were used at 5 international assembly centers. PoS(Baldin ISHEPP XXI)004 Cathode Pad Chambers at NICA/MPD J. Fedorišin (electron-ion pairs) along its trajectory. The 3.4×1.2 m 2 six-plane prototype has been reliably operated over one year and the cosmic-ray tests showed that it was capable of detecting muons with ∼80 μm spatial and ∼5 ns time resolutions. Close. Two CMS production Cathode Strip Chambers were tested for aging effects in a high-radiation environment at the Gamma Irradiation Facility at CERN. They were designed and produced in Dubna. Using photolithography instead of physical wires, the distance between sensitive elements can be reduced to a fraction of a millimetre. The ME1/1 cathode strip chambers are the part of the CMS endcap muon system. The Muon Spectrometer of the ATLAS detector at the LHC is designed to provide high quality stand-alone muon identification, momentum measurement and trigger capabilities with high pseudorapidity coverage. The design principle for a multi-wire proportional chamber with a cathode strip and delay-line readout is described. Measured noise levels are low, with the number of noisy channels well below 1%.
