The ATLAS experiment at the CERN Large Hadron Collider (LHC) has started taking data in Autumn 2008 with the inauguration of the LHC. The determination of vertex position and charged particle tracks is performed in the Inner Detector which consists of pixel and microstrip silicon sensors and of straw drift tubes with transition radiation detector capability. All three subdetectors were run in s...

We have tested the detection performance of a strip detector processed on silicon wafer grown by magnetic Czochralski (MCZ) method. This is the first time a full size Czochralski detector has been tested in a beam, although the advantages of CZ silicon have been known before. Prior to test beam measurements, the electrical characteristics of the Czochralski silicon detectors were found to be ap...

A case is presented for compelling physics at a high luminosity RHIC II collider. A comprehensive new detector system is introduced to address this physics. The experimental focus is on detailed jet tomography of the quark gluon plasma (QGP), measuring gluon saturation in the nucleus, investigating the color glass condensate, measuring effects of the QCD vacuum on particle masses, determining t...

This document describes the Cherenkov detector that is to be constructed for the Hall A neutron d2 experiment (E06-014). The inclusive nature of that experiment makes the addition of the Cerenkov counter for pion and proton rejection critical for the low energy bins. Monte Carlo and analysis of G E suggest particle rates of (assuming a 500MeV ee threshold on the the BigBite shower detector): • ...

The detection of low energy neutrinos in a large scintillation detector may provide further important information on astrophysical processes as supernova physics, solar physics and elementary particle physics as well as geophysics. In this contribution, a new project for Low Energy Neutrino Astronomy (LENA) consisting of a 50 kt scintillation detector is presented. ∗Corresponding authors. Fax: ...

ATHENA’s first detection of cold antihydrogen atoms relied on their annihilation signatures in a sophisticated particle detector. We will review the features of the ATHENA detector and its applications in trap physics. The detector for a new experiment ALPHA will have considerable challenges due to increased material thickness in the trap apparatus as well as field non-uniformity. Our studies i...

A Ring Imaging Čerenkov detector built for the BRAHMS experiment at the Brookhaven RHIC is described. This detector has a high index of refraction gas radiator. Čerenkov light is focused on a photo-multiplier based photon detector with a large spherical mirror. The combination of momentum and ring radius measurement provides particle identification from 2.5 GeV/c up to 35 GeV/c for pions and ka...

The ICARUS detector is a liquid argon time projection chamber. It provides three dimensional imaging and calorimetry of ionizing particles over a large volume, with high granularity. Its Physics program includes the study of atmospheric, solar, supernovae and beam neutrinos as well as proton decay searches. The ICARUS technology has reached maturity with the construction and test (during summer...

Results are reported from beam test measurements of one of the first commercial prototype gallium arsenide microstrip detectors. The detector consisted of 128 strips on a 50μm pitch, with a wafer thickness of 200μm. Operating at a bias of 180V, the detector produced a signal to noise ratio of 19 to 1, with a particle detection efficiency of better than 99%. The spatial resolution of the detecto...
