For the International Large Detector concept at planned Linear Collider, use of time projection chambers (TPC) with micro-pattern gas detector readout as main tracking is investigated. In this paper, results from a prototype TPC, placed in 1 T solenoidal field and read out three independent GEM-based modules, are reported. The TPC was exposed to 6 GeV electron beam DESY II synchrotron. efficiency for reconstructing hits, measurement drift velocity, space point resolution control...
The International Large Detector, ILD, is a detector concept which has been developed for the electron-positron collider ILC. optimized precision physics in range of energies between 90 GeV and 1 TeV. ILD features high precision, large volume combined silicon gaseous tracking system, together with granularity calorimeter, all inside 3.5 T solenoidal magnetic field. paradigm particle flow guiding principle design ILD. In this document required performance detector, proposed implementation...
Abstract For optimal operations in the high radiation and pileup environment of HL-LHC, CMS-HGCAL requires precise timing information at level 30 ps (RMS) for a particle shower. The time measurement silicon detector modules is performed using per-channel time-of-arrival discriminator coupled with charge to correct time-walk. module design includes access holes PCB sensor passivation enable infrared laser light be injected directly into cells. We present calibration timing-in system used...
A search for a Higgs boson decaying into two photons in proton-proton collisions at centre-ofmass energies of 7 TeV and 8 is reported. The data analysed correspond to an integrated luminosity 5.1 fb−1, recorded 2011 √ s = 5.3 2012 by the CMS experiment LHC. mass range explored 110– 150 GeV. Limits are set on cross section Standard Model photons. An excess events above expected background observed hypothesis 125 GeV, with local significance 4.1σ . global observing such anywhere estimated be...
The readout electronics of a Micromegas (MM) module consume nearly 26 W electric power, which causes the temperature electronic board to increase upto 70 oC. Increase in results damage electronics. Development gradient Time Projection Chamber (TPC) may affect precise measurement as well. Two-phase CO2 cooling has been applied remove heat from MM modules during two test beam experiments at DESY, Hamburg. Following experimental procedure, comprehensive study technique accomplished for single...
A prospective for the inclusive search of Standard Model Higgs boson in decay channel H→γγ is presented with CMS experiment at LHC. The analysis relies on a strategy to determine background characteristics and systematics from data. applied Monte QCD background, full simulation detector response. discrimination between signal exploits information photon isolation kinematics. resolution reconstructed mass profits excellent energy crystal calorimeter. discovery significance above 5 sigma...
A Micromegas (MM) based Time Projection Chamber (TPC) can meet the ILC requirements of continuous 3-D tracking, excellent spatial resolution and efficient pattern recognition. Seven MM modules which are commissioned on end-plate a Large Prototype TPC (LPTPC) at DESY, have been tested with 5 GeV electron beam, under 1 T magnetic field. Due to grounded peripheral frame modules, short drift, electric field near detector edge remain no longer parallel axis. This causes signal loss along...
A search for massive resonances decaying to a Z boson and photon is performed in events with hadronically candidate, separately light-quark b quark decay modes, identified using jet substructure advanced tagging techniques. Results are based on samples of proton-proton collisions collected the CMS detector at LHC center-of-mass energies 8 13 TeV, corresponding integrated luminosities 19.7 2.7 inverse femtobarns, respectively. The results combined those similar leptonic modes boson, same data...
Ion backflow is one of the effects limiting operation a gaseous detector at high flux, by giving rise to space charge which perturbs electric field. The natural ability bulk Micromegas suppress ion feedback very effective and can help TPC drift volume remain relatively free build-up. An efficient precise measurement fraction necessary cope up with track distortion due effect. In subtle but significant modification usual approach, we have made use two meshes in order measure for detector....
