Magnetic shielding studies of the LHCb rich photon detectors
The LHCb experiment will use two RICH detectors to provide particle identification. The Hybrid Photon Detectors (HPDs) adopted for these detectors are required to operate in the fringe field of the 4Tm LHCb dipole magnet. In fields in excess of 15G, photoelectrons are lost from the active area of an HPD. Shielding the HPDs from the fringe field is therefore essential for the efficient operation...
متن کاملPixel hybrid photon detectors for the LHCb-RICH system
The baseline option for the photon detectors of the LHCb Ring Imaging Cherenkov (RICH) subsystem is the pixel hybrid photon detector (HPD) [1]. Commercially available pixel HPDs do not fully meet the LHCb RICH requirements, namely wide area coverage over 2.6 m, single photon sensitivity in the wavelength range of 200600 nm, channel size of 2.5 x 2.5 mm and a speed compatible with the LHC bunchc...
متن کاملThe Ring Imaging Cherenkov Detectors for LHCb
The success of the LHCb experiment depends heavily on particle identification over the momentum range 2−100 GeV/c. To meet this challenge, LHCb uses a Ring Imaging Cherenkov (RICH) system composed of two detectors with three radiators. RICH1 has both aerogel and gas (C4F10) radiators, while RICH2 has only a gas (CF4) radiator. The design of RICH1 is almost complete, whereas RICH2 has been const...
متن کاملLHCb Level-0 Trigger Detectors
The calorimeter and muon systems are essential components to provide a trigger for the LHCb experiment. The calorimeter system comprises a scintillating pad detector and pre-shower, followed by electromagnetic and hadronic calorimeters. The calorimeter system allows photons, electrons and hadrons to be identified, and their energy to bemeasured. Themuon system consists of five measuring station...
متن کاملTracking and Alignment Performance of the LHCb silicon detectors
The LHCb experiment is primarily dedicated to the study of new physics through the heavy flavour decays. The tracking system of LHCb is composed of a silicon micro-strip vertex detector, two silicon strip tracker detectors and a set of straw-tube drift chambers in front of and behind a dipole generating a magnetic field. This system provides precise measure of the vertex position and high momen...
