"The photon energy resolution of the Electromagnetic Calorimeter of the BaBar detector at SLAC has been studied. The response of the calorimeter was investigated using single photons above 1 GeV from the reaction e+e- -> mu+mu-gamma. Initially a discrepancy was observed between Data and Monte Carlo simulated events. A smearing technique has been developed to correct this discrepancy, based on...

I present an overview of the proposed alignment strategy for the Ring Imaging Cherenkov Detectors in the LHCb experiment. Small misalignments of optical components in the detectors can be determined from data and corrected for in the event reconstruction. Techniques to achieve this were validated on RICH Testbeam data. Simulated LHCb data was then used to determine the effects of individual...

The RAL Front End Test Stand is being constructed to demonstrate the production of a 60 mA, 3 MeV, 50 pps, chopped H- beam suitable for future high-power proton accelerators.
Due to the high beam brightness and a desire to have online instrumentation while the accelerator is operational, a series of non-intrusive, non-destructive diagnostics, based on the photo-detachment of the outer...

The Argon Dark Matter (ArDM) is a 1-ton two phase liquid/gaseous argon scintillation/ionisation WIMP detector. The primary VUV scintillation light of argon (wavelength 128 nm) needs to be shifted to visible light in order to match the sensitivity range of the photomultiplier tubes. We discuss results from the development and optimization of wavelength shifters based on the organic...

The T2K experiment will fire an intense neutrino beam from the JPARC
facility on the east coast of Japan to the Super Kamiokande detector 295km
to the west. To measure the sub dominant theta13 lepton mixing angle, Super
Kamiokande will detect the appearence of electron flavour neutrinos from the
originally >99% pure Muon neutrino beam.
One of the major backgrounds to this electron...

T2K (Tokai to Kamioka) is a 295km long-baseline neutrino experiment in Japan, which is due to start taking commissioning data late in 2009. It is designed to measure muon-neutrino oscillations to other flavours. This will enable the measurement of some of the components of the MNSP mixing matrix. One of the UK's main contributions is the construction of an Electromagnetic Calorimeter (ECal)...

The T2K long baseline neutrino oscillation experiment will fire a neutrino beam from the JPARC facility on the east coast of Japan, 295km to the Super Kamiokande detector. At a distance of 280m from the neutrino beam source a Near Detector will be used to parametrise the beam. The optical channels of the 280m Near Detector will be instrumented using a relatively new photosensor, the...

In order to meet the physics goals of a future linear collider, a high level of hadronic jet energy resolution is required. This is best done by accurate track-shower matching, which has led to the proposal of high spatial granularity calorimetry. This talk will focus on a method of determining the positional and angular resolutions of the CALICE pre-prototype ECAL, in response to electrons....
