The Compact Muon Solenoid (CMS) experiment prepares its Phase-2 upgrade for the high-luminosity era of LHC operation (HL-LHC). Due to increase occupancy, trigger latency and rates, full electronics CMS Drift Tube (DT) chambers will need be replaced. In new design, time bin digitisation chamber signals around 1~ns, totality forwarded asynchronously service cavern at resolution. backend system in charge building primitives each chamber. These contain information level about muon candidates...
The barrel region of the Compact Muon Solenoid (CMS) experiment at Large Hadron Collider is instrumented with Drift Tube (DT) detectors. This paper describes in full details calibration DT hit reconstruction algorithm. After inter-channel synchronization has been verified through appropriate hardware procedure, time pedestals are extracted directly from distribution recorded times. Further corrections for time-of-flight and signal propagation applied as soon three-dimensional position within...
The CMS drift tubes (DT) muon detector, built for withstanding the LHC expected integrated and instantaneous luminosities, will be used also in High Luminosity (HL-LHC) at a 5 times larger luminosity and, consequently, much higher levels of radiation, reaching about 10 luminosity. Initial irradiation tests spare DT chamber CERN gamma facility (GIF++), large (∼ O(100)) acceleration factor, showed ageing effects resulting degradation cell performance. However, full simulations have shown...
In this report, results on the calibration process of Drift Tubes (DT) system Compact Muon Solenoid experiment are presented. The full commissioning procedure has been deployed in year 2008 with CMS Computing, Software and Analysis challenge (CSA08), which tested work-flow needed for data-taking during LHC start-up operations. autumn 2008, same Calibration was applied to a high statistics cosmic ray muon data taking period: Cosmic Run At Four Tesla (CRAFT) period. accurate measurement main...
The Electronics for the Drift Tube Chambers (DT) of CMS will be significantly upgraded during LHC Long Shutdown 3 (LS3). DTs are responsible tracking and triggering muons in central region CMS. As a consequence higher L1A rate set by HL-LHC, new Trigger requirements exceed present capabilities DT on-detector electronics (so called MiniCrate, MiC). For this reason, having also mind easier maintainability chamber aging mitigation arguments, replace all their MiCs LS3. phase2 on detector...
The upgrade of the acquisition for muon Drift Tube foresees relocation Sector Collector electronics, from cavern towards counting room. project requires an electrical to optical conversion by Copper Optical Fibre (CUOF) board, developed and tested in a radiation environment components qualification. More tests were performed inserting prototype actual system, with such good result that substantial production is progress. installation large number channels planned 2013 autumn, new system will...
The upgrade of the Drift Tube system CMS experiment foresee relocation electronics actually sitting on racks beside magnet from cavern to counting room. It is thus required convert signals electrical optical, for a total number 3500 channels that run at up 480 Mb/s. A Copper Optical Fiber board currently under design. divided into mother board, which hosts slow control based Field Programmable Gate Array, and four mezzanine cards, each with 8 conversion channels. prototype has been designed...
To sustain and extend its discovery potential, the Large Hadron Collider (LHC) will undergo a major upgrade in coming years, referred to as High Luminosity LHC (HLLHC), aimed increase instantaneous luminosity, 5 times larger than designed limit, and, consequently leading high levels of radiation, with goal collect 10 original integrated luminosity. The drift tube chambers (DT) CMS muon detector system is built proficiently measure trigger on muons harsh radiation environment expected during...
