Abstract With over 6 million channels, the High Granularity Calorimeter for CMS HL-LHC upgrade presents a unique data transmission challenge. The ECON ASICs provide critical stage of on-detector compression and selection trigger path (ECON-T) acquisition (ECON-D) HGCAL. ASICs, fabricated in 65 nm CMOS, are radiation tolerant up to 200 Mrad require low power consumption: < 2.5 mW/sensor-channel per chip. We report on first functionality tests ECON-D-P1 full-functionality prototype. present...
Abstract With over 6 million channels, the High Granularity Calorimeter (HGCAL) for CMS HL-LHC Upgrade presents a unique data challenge. The ECON ASICs provide critical on-detector reduction 40 MHz trigger path (ECON-T) and 750 kHz acquisition (ECON-D) of HGCAL. ASICs, fabricated in 65 nm CMOS, are rad-tolerant (600 Mrad) with low power consumption (<2.5 mW/channel). This presentation is first comprehensive description designs, functionality radiation tests ECON-T ASIC, results from full...
Test results are presented for two AMC cards, the ``CTP6'' and ``MP7''. The cards take different approaches to connectivity: CTP-6 has fully-populated backplane connectivity a 396 Gbps asymmetric, optical interface, whilst MP7 instead favours 1.4 Tbps, symmetric, all-optical interface. challenges of designing card necessitated development several test cards; which presented.
The CMS Level-1 upgraded calorimeter trigger requires a powerful, flexible and compact processing card. Calorimeter Trigger Processor Card (CTP7) uses the Virtex-7 FPGA as its primary data processor is first based card in to employ ZYNQ System-on-Chip (SoC) running embedded Linux provide TCP/IP communication board support functions. CTP7 was built from ground up AXI infrastructure modular designs with minimal time project conception final implementation.
When the LHC resumes operation in 2015, higher centre-of-mass energy and high-luminosity conditions will require significantly more sophisticated algorithms to select interesting physics events within readout bandwidth limitations. The planned upgrade CMS calorimeter trigger achieve this goal by implementing a flexible system based on μTCA standard, with modules Xilinx Virtex-7 FPGAs up 144 optical links running at speeds of 10 Gbps. improve position resolution objects, enable much improved...
Results from the completed Phase 1 Upgrade of Compact Muon Solenoid (CMS) Level-1 Calorimeter Trigger are presented. The upgrade was performed in two stages, with first running 2015 for proton and heavy ion collisions final stage 2016 data taking. trigger has been fully commissioned used by CMS to collect over 43 fb−1 since start Run II Large Hadron Collider (LHC). new designed improve performance at high luminosity large number simultaneous inelastic per crossing (pile-up). For this purpose...
The CMS Level-1 calorimeter trigger is being upgraded in two stages to maintain performance as the LHC increases pile-up and instantaneous luminosity its second run. In first stage, improved algorithms including event-by-event corrections are used. New for heavy ion running have also been developed. higher granularity inputs a time-multiplexed approach allow position energy resolution. Data processing both of upgrade performed with new, Xilinx Virtex-7 based AMC cards.
We present a design for the Phase-1 upgrade of Compact Muon Solenoid (CMS) calorimeter trigger system composed FPGAs and Multi-GBit/sec links that adhere to μTCA crate Telecom standard. The will implement algorithms create collections isolated non-isolated electromagnetic objects, tau objects jet objects. are organized in several steps with progressive data reduction. These include particle cluster finder reconstructs overlapping clusters 2x2 towers applies electron identification, overlap...
As the LHC increases luminosity and energy, it will become increasingly difficult to select interesting physics events remain within readout bandwidth limitations. An upgrade CMS Calorimeter Trigger implementing more complex algorithms is proposed. It utilizes AMC cards with Xilinx FPGAs running in microTCA crate card interconnections via backplanes optical links operating at up 10 Gbps. Prototype Virtex-6 Virtex-7 have been built software frameworks for operation monitoring developed. The...
The Compact Muon Solenoid (CMS) experiment is currently installing upgrades to their Calorimeter Trigger for LHC Run 2 ensure that the trigger thresholds can stay low, and physics data collection will not be compromised. electronics upgraded in two stages. Stage-1 2015 upgrade some links from copper optical existing calorimeter so algorithms improved we do lose valuable before stage-2 fully installed by 2016. Stage-2 replace at CMS with a micro-TCA link system. It requires updates back-ends,...
