The final oscillation analysis of the complete set of data collected by CHORUS in the years 1994–1997 is presented. Reconstruction algorithms of data extracted by electronic detectors were improved and the data recorded in the emulsion target were analysed by new automated scanning systems, allowing the use of a new method for event reconstruction in(More)
1. A Transistor-array for Parallel BTI-effects Measurement Takumi Uezono, Tadamichi Kozaki, Hiroyuki Ochi, and Takashi Sato/Kyoto Univ. A novel test structure, which facilitates efficient measurement of threshold voltage (Vth) variation and degradation caused by bias temperature instability (BTI) effects, is proposed. The proposed structure consists of a(More)
CHORUS is an ongoing experiment to search for ! oscillation in the CERN SPS Wide Band Neutrino Beam. Emulsion is used as an active target. The beamexposure of the 1st-run started in May 1994, and nished in Oct.1995. During 12 months of exposure, 2 10 19 protons were sent on the beam target and 430,000 neutrino interactions in the emulsion were recorded. A(More)
Southern hybridization analysis of the MASP1 gene using an intron-specific probe detected a single band. An exon-specific probe detected several bands. PCR of genomic DNA using several exon-specific primer sets of MASP1 produced short and long products. Sequence of the shorter products corresponded to the processed pseudogene of MASP1. By fluorescence in(More)
A scintillating ber tracker system consisting of more than one million bers has been successfully constructed and made operational for the CERN WA95/CHORUS experiment. The design and construction of the tracker system as well as its opto-electronic readout are described. The performance of the detector with high energy muons is presented.
The CHORUS experiment has successfully nished run I (320 000 recorded CC in 94/95) and performed half of run II (225 000 CC in 96). The analysis chain was exercised on a small data sample for the muonic decay search using for the rst time fully automatic emulsion scanning. This pilot analysis, resulting in a limit sin(2 ) 3 10 , con rms that the CHORUS(More)
