The Vertex Locator (VELO) is a silicon microstrip detector that surrounds the proton-proton interaction region in LHCb experiment. performance of during first years its physics operation reviewed. system operated vacuum, uses bi-phase CO2 cooling system, and sensors are moved to 7 mm from LHC beam for data taking. stability these characteristic features described, details material budget given. calibration timing processing algorithms implemented FPGAs described. fully characterised. have...
The LHCb Vertex Locator (VELO) is a silicon strip detector designed to reconstruct charged particle trajectories and vertices produced at the interaction region. During first two years of data collection, 84 VELO sensors have been exposed range fluences up maximum value approximately 45 × 1012 1 MeV neutron equivalent (1 neq). At operational sensor temperature −7 °C, average rate current increase 18 μA per fb−1, in excellent agreement with predictions. effective bandgap has determined using...
Precise knowledge of the location material in LHCb vertex locator (VELO) is essential to reducing background searches for long-lived exotic particles, and identifying jets that originate from beauty charm quarks. Secondary interactions hadrons produced beam-gas collisions are used map VELO. Using this map, along with properties a reconstructed secondary its constituent tracks, $p$-value can be assigned hypothesis originates interaction. A validation procedure presented using photon...
Abstract The LHCb detector has undergone a major upgrade for LHC Run 3. This Upgrade I facilitates operation at higher luminosity and utilises full-detector information the collision rate, critically including use of vertex information. A new locator system, VELO Upgrade, been constructed. core element are double-sided pixelated hybrid silicon modules which operate in vacuum close to beam high radiation environment. construction quality assurance tests these described this paper. incorporate...
This article describes the high-speed system designed to meet challenging requirements for readout of new pixel VErtex LOcator (VELO) upgraded LHCb experiment. All elements electronics chain will be renewed cope with requirement ~40-MHz full-event rate. The sensors equipped VeloPix ASICs and placed at ~5 mm from Large Hadron Collider (LHC) beams in a secondary vacuum tank an extremely high nonhomogeneous radiation environment. front-end (FE) highest occupancy have pixel-hit rates above ~900...
The results of E-190 experiment (project Thermalization) with 50 GeV proton beam irradiation SVD-2 setup are presented. MC simulation has shown the linear dependence number photons detected in electromagnetic calorimeter and average neutral pions. Multiplicity distribution pion, N0, for total particles event, Ntot = Nch + obtained corrections on acceptance, triggering efficiency event reconstruction. scaled variance pion fluctuations, ω D/ < N0 >, versus multiplicity is measured....
The new LHCb Vertex Locator (VELO) for LHCb, comprising a pixel detector and readout electronics, will be installed in 2021 data taking Run 3 at the LHC. electronics centers around "VeloPix" ASIC front-end operating trigger-less 40MHz. A custom serializer, called gigabit wireline transmitter (GWT), associated protocol have been designed VeloPix. GWT are sent from serializers of VeloPix line rate 5.12 Gb/s, reaching total 2–3 Tb/s full VELO detector. Data over 300-m optic-fiber links to...
The Large Hadron Collider beauty (LHCb) detector is designed to detect decays of b- and c- hadrons for the study CP violation rare decays. At end LHC Run 2, many LHCb measurements remained statistically dominated. In order increase trigger yield purely hadronic channels, hardware will be removed, read out at 40 MHz. This, in combination with five-fold luminosity, requires radical changes LHCb's electronics, and, some cases, replacement entire sub-detectors state-of-the-art technologies....
