The Multi-Pixel Photon Counter (MPPC) is an APD array operated in Geiger mode, marketed by Hamamatsu. These devices achieve comparable performance to PMTs, with the advantages of compactness and insensitivity to magnetic fields. They have great potential in HEP applications, and are being used in the ND280 near detector of the T2K long-baseline neutrino experiment. Results from the testing and...

Information from the tracking, calorimetry and muon detection systems of the CMS detector at the Large Hadron Collider at CERN, can be combined to give a holistic description of a proton-proton collision in terms of photons, electrons, muons and hadrons. A 'particle flow' technique is presented which seeks to determine the energy and momenta of these particles. By decomposing events in this...

The Vertex Locator (VeLo) is a silicon based particle detetor in the LHCb experiment. The testbeam data taken with 10 final production VeLo modules exhibited the effects of crosstalk. A method has been developed to correct the data for this effect. A large amount of crosstalk is seen in the data, suggesting that its cause is a combination of charge sharing in the readout cables and an offset...

The Ring Imaging Cherenkov (RICH) detectors of the LHCb experiment, at the Large Hadron Collider (LHC), have been built to provide charged particle identification. Hybrid Photon Detectors (HPDs) are used to detect the Cherenkov photons produced in the RICH radiators. Each HPD required extensive testing and categorisation before being mounted in the RICH. A subsample of 74 HPDs underwent...

In the proposed CLIC Extraction Line Design, coherently produced lepton pairs possess a significant energy distribution. In the bending region, this translates to high dispersion and possible particle loss. To prevent magnet damage, masks are positioned between the magnets to absorb these losses, of which this study analyses the effect of these lost particles. Using physics-in-matter...
