Hanohano:A Deep Ocean Antineutrino Observatory (2008)

Batygov, M., Dye, S. T., Learned, J. G., Matsuno, S., Pakvasa, S., Varner, G.

This paper presents the science potential of a deep ocean antineutrino observatory being developed at Hawaii and elsewhere. The observatory design allows for relocation from one site to another....

Measuring energy dependent polarization in soft gamma-rays using Compton scattering in PoGOLite (2007)

Axelsson, M., Engdegård, O., Ryde, F., Larsson, S., Pearce, M., Hjalmarsdotter, L., ...

Linear polarization in X- and gamma-rays is an important diagnostic of many astrophysical sources, foremost giving information about their geometry, magnetic fields, and radiation mechanisms....

Search for Invisible Decay of the Υ(1S) (2007)

Tajima, O., Hayashii, H., Hazumi, M., Inami, K., Iwasaki, Y., Uehara, S., ...

We report results of a search for the invisible decay of the Υ(1S) via the Υ(3S)→π+π-Υ(1S) transition using a data sample of 2.9 fb^{-1} at the Υ(3S) resonance. The data were collected with...

Observation of B^+ → Λ^+_c Λ^-_c K^+ and B^0 → Λ^+_c Λ^-_c K^0 Decays (2006)

Gabyshev, N., Abe, K., Abe, K., Adachi, I., Aihara, H., Asano, Y., ...

We report the first measurements of the doubly charmed baryonic B decays B → Λ^+_c Λ^-_c K. The B+ → Λ^+_c Λ^-_c K+ decay is observed with a branching fraction of (6.5^{+1.0}_{-0.9}...

Earth Radioactivity Measurements with a Deep Ocean Anti-neutrino Observatory (2006)

Dye, S. T., Guillian, E., Learned, J. G., Maricic, J., Matsuno, S., Pakvasa, S., ...

We consider the detector size, location, depth, background, and radio-purity required of a mid-Pacific deep-ocean instrument to accomplish the twin goals of making a definitive measurement of the...

Antarctic Impulsive Transient Antenna (ANITA) instrumentation (2004)

Naudet, C. J., Barwick, S., Beatty, J., Besson, D., Clem, J., Coutu, S., ...

We will report on the details of the ANITA instrument. This instrument is fundamentally a broadband antenna, which is arrayed and constructed in such a way as to be optimized for the detection and...

The Data Acquisition System Based on PMC Bus (2003)

Igarashi, Y., Fujii, H., Higuchi, T., Ikeno, M., Inoue, E., Itoh, R., ...

High energy physics experiments in KEK/Japan rush into over KHz trigger stage. Thus, we need a successor of the data acquisition(DAQ) system that replaces the CAMAC or FASTBUS systems. To meet these...

Development of a PCI Based Data Acquisition Platform for High Intensity Accelerator Experiments (2003)

Higuchi, T., Fujii, H., Ikeno, M., Igarashi, Y., Inoue, E., Itoh, R., ...

Data logging at an upgraded KEKB accelerator or the J-PARC facility, currently under commission, requires a high density data acquisition platform with integrated data reduction CPUs. To follow...

A Detailed Monte-Carlo Simulation for the Belle TOF System (2002)

Nam, J. W., Choi, Y. I., Kim, D. W., Kim, J. H ., Casey, B. C. K., Jones, M., ...

We have developed a detailed Monte Carlo simulation program for the Belle TOF system. Based on GEANT simulation, it takes account of all physics processes in the TOF scintillation counters and...

The Cherenkov Correlated Timing Detector: Beam Test Results from Quartz and Acrylic Bars (1995)

Kichimi, H., Sugaya, Y., Yamaguchi, H., Yoshimura, Y., Kanda, S., Olsen, S., ...

Several prototypes of a Cherenkov Correlated Timing (CCT) Detector have been tested at the KEK-PS test beam line. We describe the results for Cherenkov light yields and timing characteristics from...
