Pixel 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 کاملPerformance of the LHCb RICH detector at the LHC
The LHCb experiment has been taking data at the Large Hadron Collider (LHC) at CERN since the end of 2009. One of its key detector components is the Ring-Imaging Cherenkov (RICH) system. This provides charged particle identification over a wide momentum range, from 2-100 GeV/c. The operation and control, software, and online monitoring of the RICH system are described. The particle identificati...
متن کاملMagnetic 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 کاملThe LHCb upgrade detector
The LHCb experiment has been designed to perform precision measurements of CP asymmetries and to investigate potential effects of physics beyond the Standard Model. Results obtained from data collected in 2010 and 2011 show that the detector is robust and functioning well. While LHCb will be able to measure a host of interesting channels in heavy flavour decays in the coming years, a limit of a...
متن کاملThe LHCb Detector Description Framework
A coherent O-O framework has been developed for describing the LHCb experimental apparatus to be used by the simulation, reconstruction and analysis applications. This framework is used for the realization of the detector data service, which is one of the main components of the GAUDI architecture in use in LHCb. Examples of detector description data are: the geometry and alignment parameters, t...
