Abstract For the High Luminosity phase of LHC (HL-LHC), CMS detector electronics require precise and accurate timing to discriminate pileup events. The upgraded Back-End Barrel Electromagnetic Calorimeter supply required high-precision clock (Time Interval Error σ < 5 ps) Front-End. However, after a reset is applied on distribution system, resulting not accurately repetitive but it gives an up 10 ps offset for each FPGA node chain. That uncertainty total skew with maximum being N x...
Abstract In preparation of the operation CMS electromagnetic calorimeter (ECAL) barrel at High Luminosity Large Hadron Collider (HL-LHC) entire on-detector electronics will be replaced. The new readout comprises 12240 very front end (VFE), 2448 (FE) and low voltage regulator (LVR) cards arranged into towers (RTs) five VFEs, one FE LVR card. results testing RT final prototype CERN's CHARM mixed field facility PSI's proton irradiation are presented. They demonstrate proper functioning in...
The high luminosity expected in the second phase of upgrades Large Hadron Collider (LHC phase-2 upgrades) will pose unprecedented challenges to its four experiments terms collisions density—also known as pile-up—per beam crossing. Disentangling vertices 200 simultaneous every 25 ns requires granularity detectors, well extremely precise and stable timing. While short-term timing stability is usually a concern addressed distribution systems, long-term variations due changing environmental...
Abstract For the CERN LHC phase 2, barrel region of CMS electromagnetic (ECAL EB) and hadronic calorimeters (HCAL HB) require new back-end electronics for their readout. To this purpose, a first version ATCA-based blade, Barrel Calorimeter Processor (BCPv1), has been developed. The performance optical links as well clock distribution are also presented here. BCPv1 tested together with front-end trigger boards, DAQ TCDS Hub (DTH) [1], to demonstrate that meets required specifications.
The design and performance of the upgraded CMS Level-1 Trigger Barrel Muon Track Finder (BMTF) is presented. Monte Carlo simulation data as well cosmic ray from a muon detector slice test have been used to study in detail new track finder. architecture based on twelve MP7 cards each which uses Xilinx Virtex-7 FPGA can receive transmit at 10 Gbps 72 input output fibers. According Upgrade TDR BMTF receives trigger primitive are computed using both RPC DT transmits number candidates Global...
The CMS ECAL Phase 2 Front-End (FE) card is designed to provide streaming of digitized data generated on the Very-Frond-End (VFE) cards back-end electronics system based Barrel Calorimeter Processor (BCP) ATCA modules. FE intended utilize links developed within Versatile Link common project. will contain four lpGBT ASICS with corresponding versatile link plus optical first prototype was validate clock distribution, high speed serial as well other specific technical features future design...
To maintain the excellent performance of LHC during its Run-1 also in Run-2, Level-1 Trigger Compact Muon Solenoid experiment underwent a significant upgrade. One part this upgrade was re-organisation muon trigger path from subsystem-centric view which hits drift tubes, cathode strip chambers, and resistive plate chambers were treated separately dedicated track-finding systems, to one complementary detector systems for given region (barrel, overlap, endcap) are merged already at level. This...
After the high-luminosity upgrade of LHC, electromagnetic calorimeter and hadron CMS Barrel must cope with an increase in number interactions per bunch crossing radiation levels. implements a sophisticated two-level triggering system composed Level-1, instrumented by custom-designed hardware boards, software High-Level-Trigger. To this end, off-detector electronics have been redesigned increased capabilities, exploiting granularity both calorimeters at Level-1. The paper focuses on new...
