14. The Dark Energy Camera - a New Instrument for the Dark Energy Survey

Prof. Klaus Honscheid (Ohio State University)

Detector Technology and R&D

The discovery that the universe is accelerating, not slowing down from the mass it contains, is the surprise that sets the initial research program of 21st Century cosmology. The Dark Energy Survey (DES) is a next generation sky survey aimed directly at understanding this mystery. DES is designed to measure the dark energy equation of state parameter with four complementary techniques: galaxy...

30. Local alignment of the BaBar Silicon Vertex Tracking detector

Zijin Guo (Johns Hopkins University)

Detector Technology and R&D

The BaBar Silicon Vertex Tracker (SVT) is a five-layer double-sided silicon detector designed to provide precise measurements of the position and direction of primary tracks, and to fully reconstruct low-momentum tracks produced in e+e- collisions at the PEP-II asymmetric collider at SLAC. This presentation will describe the design, implementation, performance, and validation of the local...

313. An imaging time-of-propagation system for charged particle identification at a Super B factory

Kurtis Nishimura (University of Hawaii)

Detector Technology and R&D

Super B factories that will perform precision tests of the flavor sector of the Standard Model and searches for new physics will demand excellent charged particle identification (PID), particularly K/π separation, for momenta up to 4 GeV/c, as well as the ability to operate under beam backgrounds significantly higher than current B factory experiments. We describe an Imaging...

261. Prospects for Upgrade of KEKB

Prof. Kay Kinoshita (University of Cincinnati)

Detector Technology and R&D

The Belle detector at the KEKB electron-positron collider has collected nearly 1~ab$^{-1}$ of data in its decade of operation. The KEKB group has proposed Super-KEKB, an upgrade of KEKB to increase the luminosity by two orders of magnitude during a three-year shutdown, with an ultimate goal of 8 x 10^35/cm^2/s luminosity. To exploit the improved luminosity, an upgrade of the Belle detector...

37. Cerenkov Light Diagnostics for Superconducting Cavities

Aram Apyan (Illinois Institute of Technology)

Detector Technology and R&D

Field emission is one of the major problems limiting rf cavity performance in accelerators. Superconducting cavities are made of thin metal shells in a metal liquid helium vessel. This system can be viewed as a Cerenkov radiator between a set of mirrors. Field emitted electrons can punch through the cavity wall and generate Cerenkov light in helium which can be collected by appropriate...
