269. ATLAS Silicon Microstrip Tracker Operation

Dr Zdenek Dolezal (Institute of Particle and Nuclear Physics)

Detector Technology and R&D

The ATLAS experiment at the CERN Large Hadron Collider (LHC) has started taking data last autumn with the inauguration of the LHC. The SemiConductor Tracker (SCT) is the key precision tracking device in ATLAS, made up from silicon micro-strip detectors. The completed SCT has been installed inside the ATLAS experimental hall. Since then the detector was operated for many months under realistic...

131. Development of FTK Architecture: A Fast Hardware Track Trigger for the ATLAS Detector

Mr Anton Kapliy (University of Chicago)

Detector Technology and R&D

As the LHC luminosity is ramped up to the design level of 10^34 cm−2 s−1 and beyond, the high rates, multiplicities, and energies of particles seen by the detectors will pose a unique challenge. Only a tiny fraction of the produced collisions can be stored on tape and immense real-time data reduction is needed. An effective trigger system must maintain high trigger efficiencies for the...

15. ATLAS Pixel Radiation Monitoring with HVPP4 System

Igor Gorelov (Department of Physics and Astronomy, Univ. of New Mexico, USA)

Detector Technology and R&D

We will describe the principles of radiation damage monitoring using the current measurements of the pixel sensors to be provided by the circuits of ATLAS Pixel Detector HVPP4 System. The dependence of the leakage current with respect to an integrated luminosity at several temperature scenarios will be presented. Based on the analysis we have evaluated the sensitivity...

412. Upgrade of CMS HCAL for SLHC

Detector Technology and R&D

The Compact Muon Solenoid (CMS) detector is in the planning phase of a major upgrade in preparation for the upgrade of the Large Hadron Collider (LHC) to the Super-LHC (SLHC). The SLHC will feature a significant increase in the instantaneous luminosity, leading to up to 200 collisions per interaction. In addition, the sustained radiation from the initial phase of LHC operations will...

240. RADIATION-HARD ASICS FOR SLHC OPTICAL DATA TRANSMISSION

Prof. K.K. Gan (The Ohio State University)

30/07/2009, 16:15

Detector Technology and R&D

We have designed several ASICs for the optical link upgrades of the new silicon trackers of the ATLAS experiment at the planned upgrades of the LHC, CERN. The ASICs include a high-speed driver for VCSELs, a receiver/decoder for the signal received at the PIN diode, and a clock multiplier to produce a higher frequency clock to serialize the data for transmission. These chips were designed using...

242. STUDY OF THE RADIATION-HARDNESS OF VCSEL/PIN ARRAYS

Waruna Fernando (The Ohio State University)

30/07/2009, 16:40

Detector Technology and R&D

We investigate the feasibility of using VCSEL and PIN for the optical links at the silicon trackers of the ATLAS experiment at the planned upgrades of the LHC, CERN. We irradiated VCSEL and PIN with 24 GeV/c protons at CERN up to the equivalent SLHC fluence of 2.6 x 10^15 p/cm2, including a 50% safety factor. The GaAs VCSEL arrays were fabricated by Optowell and Advanced Optical Component...

126. ArgoNeuT: A Liquid Argon Time Projection Chamber Test in the NuMI Beamline

Dr Mitchell Soderberg (Yale University)

30/07/2009, 17:05

Detector Technology and R&D

Liquid Argon Time Pro jection Chamber (LAr TPC) detectors are ideally suited for studying neutrino interactions and probing the pa- rameters that characterize neutrino oscillations. The ability to drift ionization particles over long distances in purified argon and to trigger on abundant scintillation light allows for excellent particle identifica- tion and triggering capability. In...

7. Novel Multi-pixel Silicon Photon Detectors and Applications in T2K.

Detector Technology and R&D

T2K is Tokai to Kamioka long baseline neutrino oscillation experiment (Japan). The goal of the experiment is to measure theta13 neutrino oscillation parameter by nu-e appearance from nu-mu beam. The near off-axis detector, ND280, consists of several sub-detectors in 0.2T magnetic field, with photon readout scheme. This necessitates usage of the efficient, high performance photon detector that...
