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...
The Upstream Tracker (UT) silicon strip detector, one of the central parts tracker system modernised LHCb experiment, will use a new 128-channel readout ASIC called SALT. It extract and digitise analogue signals from UT sensors, perform digital signal processing transmit serial output data. SALT is being designed in CMOS 130 nm process uses novel architecture comprising analog front-end fast (40 MSps) ultra-low power (<0.5 mW) 6-bit ADC each channel. prototype ASICs important functional...
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...
SALT, a new dedicated readout Application Specific Integrated Circuit (ASIC) for the Upstream Tracker, silicon detector in Large Hadron Collider beauty (LHCb) experiment, has been designed and developed. It is 128-channel chip using an innovative architecture comprising low-power analogue front-end with fast pulse shaping 40 MSps 6-bit Analog-to-Digital Converter (ADC) each channel, followed by Digital Signal Processing (DSP) block performing pedestal Mean Common Mode (MCM) subtraction zero...
Three-dimensional (3D) printing, specifically digital light processing (DLP) technique, can be used to manufacture plastic scintillators of any shape. The purpose this study was determine the output DLP 3D-printed for dosimetry applications. Two types with dimensions 10 mm × were fabricated using 3D-printing at Hanyang University, South Korea. these samples measured and compared that a commercial scintillator same dimensions, RP-408, produced by casting. emitting violet blue had lower...
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 LHCb experiment is preparing for a major upgrade in 2018-2019. One of the key components new silicon tracker situated upstream analysis magnet experiment. Upstream Tracker (UT) will consist four planes strip detectors, with each plane covering an area about 2 m$^2$. An important consideration these detectors their performance after they have been exposed to large radiation dose.

Knowledge of the beam properties in proton therapy through monitoring is essential, ensuring an effective dose delivery to patient. In clinical practice, currently used interceptive ionisation chambers require daily calibration and suffer from a slow response time. A new non-invasive method for online under development based on silicon multi-strip sensor LHCb VELO (VErtex LOcator), originally experiment at CERN. The proposed relies halo measurements. Several changes system setup were...
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.
