The ME1/1 cathode strip chambers are the part of the CMS endcap muon system. They were designed and produced in Dubna. The
chambers have been installed in the detector and commissioning has been completed. This paper describes chamber readout electronics
and presents the results of the tests with cosmicray muons.

Seventy-six serial ME1/1 cathode strip chambers have been produced in Dubna. These chambers are the coordinate detectors of
the first muon station of the CMS detector at CERN. This paper describes the design of the chamber, its main mechanical parameters,
and the results of the cosmic ray test.

The influence of the high background rates on the Cathode Strip Chamber (CSC) anode trigger ability has been studied. The
investigation has been made with a P3 prototype of the CSC of ME1/1 Endcap muon station of the CMS experiment (CERN). The
work has been done at the Gamma Irradiation Facility (GIF, CERN). P3 has been installed at the SPS X5c muon beam line in a
background field of 137Cs source. The CSC timing resolution and the track registration efficiency as a function of gamma rate are presented.

The spatial resolution of the outer part of the ME1/1 muon station has been studied with CRAFT08 (Cosmic Rays At Four Tesla-2008)
data at the CMS detector (CERN). The ME1/1 Cathode Strip Chamber (CSC) layer spatial resolution as a function of the CMS solenoid
magnetic field is presented. The influence of the strip width and anode wire tilt on the spatial resolution has been studied.
Finally, the spatial resolution for the ME1/1 6-layer CSC was calculated and the ME1/1 outer part spatial resolution was estimated. 相似文献

We estimate the energy losses in the case of deep-inelastic scattering on nuclear targets in terms of the effective change
of the virtual photon energy. Our phenomenological results are in reasonable agreement with theoretical calculations. The
difference in secondary production processes in hard and soft interactions is discussed.

Distortion of the electric field near the edge of the operation region of the Cathode Strip Chamber (CSC) of the first Muon
Endcap Station (ME1/1) of the Compact Muon Solenoid (CMS) is studied. The distortions of the shape and the magnitude of the
electric field that arise from the presence of the insulating frame, which supports the anode wire array, are investigated.
The electric field calculation is done with the aid of the boundary elements method.

The theory of thermal photon and dilepton emission from a hot and dense hadronic gas, as well as from the Quark-Gluon Plasma, is reviewed in the context of extracting in-medium properties of the matter constituents. In phenomenological applications to ultrarelativistic heavy-ion collisions we focus on recent photon and dilepton spectra as measured by WA98 and CERES/NA45, respectively, at CERN-SPS energies. 相似文献

The inclusive spectrum in the central region, ρn(x→0)/<ρ(x→0)> is considered as a function of the multiplicity of charged secondariesn/〈n〉. The calculations in framework of the quark-gluon strings model and the minijet model agree with theSppS-collider data, but both models predict a slow dependence of this value on the energy. 相似文献

This paper summarizes our study on microwave and millimeter-wave propagation in rain with special emphasis on the effects of polarization. Starting from a recount of our past findings, we will discuss developments with these and how they are connected with subsequent research. 相似文献

Data, obtained from p-p collisions at centre-of-mass energies between 31 and 63 GeV, are presented on inclusive and semi-inclusive correlations between forward emitted neutrons and charged particles observed in an omnidirectional hodoscope. A total absorption spectrometer was used to detect the neutrons and to measure their energy. Significant correlations are observed over the whole rapidity range. The data suggest that neutrons result from the decay of clusters emitted in the fragmentation region. 相似文献

In pp collisions at √s = 44.7 and 62.3 GeV, where each proton fragments into at least one low-pT, high-x meson or baryon, no correlations between the particle momenta are found for ππ, πK, KK, and pπ pairs. The ππ data show a preference for the formation of electrically neutral ππ systems. The KK data show the influence of strangeness conservation. For pp and pΛ final states, the momentum dependence of the correlation ratio R can be described by the scaling variable z = (1 ? x1)(1 ? x2). Small deviations from factorization are discussed. 相似文献
