Experimental study of neutral and charged current cross sections and Y-distributions for (anti) neutrinos

Presents here a measurement of the cross section ratio, r, of neutrino and antineutrino induced charged current events and also the ratios, R and R, of the neutral to charged current cross sections for E/sub h />2.0 GeV. In addition they give the distribution in the inelasticity, y(=E/sub h//E/sub nu /) for all four processes is given. The data were collected using the CHARM electronic neutrino detector in the CERN 200 GeV/c narrow band neutrino beam. (4 refs)

First results from the CERN-Hamburg-Amsterdam-Rome-Moscow neutrino experiment

Preliminary results of the neutrino counter experiment carried out by the CHARM collaboration are presented. They cover the following topics: Study of the strength and the structure of the neutral current in inclusive reactions on an isoscalar target. Neutrino scattering on electrons. Measurement of the polarization of positive muons produced in high-energy antineutrino interactions**). 177 We present preliminary results of three neutrino experiments which make use of the novel features of the new neutrino detector of the CHARM (CERN-Hamburg-Amsterdam-Rome-Moscow) Collaboration. The experiments were performed in the neutrino beams of the 400 GeV Super Proton Synchrotron (SPS) accelerator at CERN

Performance of a large system of proportional drift tubes for a fine-grain calorimeter

The features of proportional counters and of drift chambers have been combined in a single detector element. For a fine-grain calorimeter used in a neutrino experiment a system of 13 000 counters has been built. The performance and long-term stability of the proportional drift tubes and the electronics are discussed
