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...
Abstract Discotic columnar mesophase behaviour exhibited by ten metal-free and copper 1,4,8,11,15,18,22,25- octa-alkylphthalocyanines has been characterised optical microscopy, differential scanning calorimetry, x-ray diffraction electronic absorption spectroscopy. Compounds with side-chains as short hexyl exhibit one or more mesophases, a total of three different mesophases are apparent for the series whole. The highest temperature is assigned Dhd. At lower temperatures, some compounds...
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...
Vertex locator (VELO) is a silicon microstrip detector situated around the interaction point in large Hadron Collider beauty (LHCb) spectrometer at Large Collider. The LHCb experiment dedicated to studying charge conjugation and parity symmetry violation heavy flavor sector rare decays of B mesons. precise reconstruction both primary secondary vertices, obtained by VELO, crucial selection signal events containing b c quarks lifetime measurements. VELO consists two retractable parts that...
