The Compact Muon Solenoid (CMS) detector is described. operates at the Large Hadron Collider (LHC) CERN. It was conceived to study proton-proton (and lead-lead) collisions a centre-of-mass energy of 14 TeV (5.5 nucleon-nucleon) and luminosities up 1034 cm−2 s−1 (1027 s−1). At core CMS sits high-magnetic-field large-bore superconducting solenoid surrounding an all-silicon pixel strip tracker, lead-tungstate scintillating-crystals electromagnetic calorimeter, brass-scintillator sampling hadron...
This report presents the capabilities of CMS experiment to explore rich heavy-ion physics programme offered by CERN Large Hadron Collider (LHC). The collisions lead nuclei at energies , will probe quark and gluon matter unprecedented values energy density. prime goal this research is study fundamental theory strong interaction — Quantum Chromodynamics (QCD) in extreme conditions temperature, density parton momentum fraction (low-x).
The CMS Hadron Calorimeter in the barrel, endcap and forward regions is fully commissioned. Cosmic ray data were taken with without magnetic field at surface hall after installation experimental hall, hundred meters underground. Various measurements also performed during few days of beam LHC September 2008. Calibration parameters extracted, energy response HCAL determined from test has been checked.
The pixel detector of the Compact Muon Solenoid experiment consists three barrel layers and two disks for each endcap. was installed in summer 2008, commissioned with charge injections, operated 3.8 T magnetic field during cosmic ray data taking. This paper reports on first running experience presents results tracker performance, which are found to be line design specifications this detector. transverse impact parameter resolution measured a sample high momentum muons is 18 microns.
During autumn 2008, the Silicon Strip Tracker was operated with full CMS experiment in a comprehensive test, presence of 3.8 T magnetic field produced by superconducting solenoid. Cosmic ray muons were detected muon chambers and used to trigger readout all sub-detectors. About 15 million events tracker collected. The efficiency hit track reconstruction measured be higher than 99% consistent expectations from Monte Carlo simulation. This article details commissioning performance cosmic muons.
The alignment system for the muon spectrometer of CMS detector comprises three independent subsystems optical and analog position sensors. It aligns chambers with respect to each other central silicon tracker. System commissioning at full magnetic field began in 2008 during an extended cosmic ray run. succeeded tracking movements up 18 mm rotations several milliradians under forces. Depending on coordinate subsystem, achieved chamber precisions 140–350 μm 30–200 μrad, close precision...
In the context of Franco-Soviet cooperation, a seismic survey was carried out on Romashkino reservoir in Tatar Republic (USSR). This involved evaluating azimuthal anisotropy parameters from S-wave VSPs recorded three wells and surface line, latter order to monitor any lateral variations parameters. this paper we present results which indicate particular that for two oil production has been established, rate appears be proportional figures. seems confirm hypothesis are asociated with presence...
Prototype of the fast timing Cherenkov detector, applicable in high-energy collider experiments, has been developed basing on modified Planacon XP85012 MCP-PMT and fused silica radiators. We present reasons description modification, amplitude characteristics prototype including summary detector's response particle hits at oblique angles performance high illumination rates.
The Fast Interaction Trigger (FIT) detector will be essential for the operation of ALICE experiment at CERN during Run 3 and 4 LHC . FIT serve as an interaction trigger, luminometer, first indicator vertex position, forward multiplicity counter. It also provide precise collision time TOF-based particle identification, yield centrality plane flow measurements, measure cross sections diffractive processes. In order to cope with increased rate up 1 MHz in proton-proton (pp) collisions 50 kHz...
The pilot gallium‐germanium installation with 7 t of Ga metal is described. Preliminary results the yields 71Ge and 69Ge from cosmic rays are given. possibility conducting a calibrating experiment using target Cr neutrino source produced enriched chromium considered.
In the framework of HADES (High Acceptance DiElectron Spectrometer) collaboration we are developing Time Of Flight (TOF) wall subdetector. order to efficiently select events with e/sup +/e/sup -/ pairs produced in nuclear matter, TOF must be able resolve electrons from pions up 0.5 GeV/c and protons 2 GeV/c. Because short flight path about m requires a 100-150 ps time resolution, building granular system made scintillator rods readout on both ends by means photomultipliers, capable such performance.
