The LHC Compact Muon Solenoid experiment Detector Control System

The Compact Muon Solenoid Experiment

Optical transmission characteristics of multi-mode synthetic silica-core bers between 325 nm and 800 nm were studied in situ while irradiated with neutrons. In one case, ber samples were placed near the core of a 10-kWatt reactor; in the other, fast neutrons generated by p(18 MeV) + Be reaction in a cyclotron, irradiated the bers. The neutron uence in both studies totaled 10 15 n=cm 2. Both of ...

The Compact Muon Solenoid Experiment

The Compact Muon Solenoid Experiment

Relativistic heavy ion beams are an intense source of (quasireal) photons with a spectrum extending up to several hundred GeV, due to the high charge Z and the large energy of the ions. In this note we discuss the possibility of using this in peripheral collisions for photon-photon physics. We discuss the total luminosities that can be achieved with diierent ion species. In order to suppress ce...

Characterizing a High Throughput Computing Workload: The Compact Muon Solenoid (CMS) Experiment at LHC

High throughput computing (HTC) has aided the scientific community in the analysis of vast amounts of data and computational jobs in distributed environments. To manage these large workloads, several systems have been developed to efficiently allocate and provide access to distributed resources. Many of these systems rely on job characteristics estimates (e.g., job runtime) to characterize the ...

Jet Physics in Heavy Ion Collisions with Compact Muon Solenoid detector at the LHC

The status of CMS jet simulations and physics analysis in heavy ion collisions is presented. Jet reconstruction and high-pT particle tracking in the high multiplicity environment of heavy ion collisions at the LHC using the CMS calorimetry and tracking system are described. The Monte Carlo tools used to simulate jet quenching are discussed.
