Abstract

In this paper we present the results from the measurements made with the MUNU TPC at 1bar pressure of CF4 in the energy region below 1 MeV. Electron events down to 80 keV are successfully measured. The electron energy and direction are reconstructed for every contained single electron above 200 keV. As test the 137Cs photopeak is reconstructed by measuring both the energy and direction of the Compton electrons in the TPC., Comment: 19 pages, 9 figures (6 figures in color); Figure 10 has been deleted from [v1]. Additional paragraph has been included; Manuscript is submitted to Nuclear Inst. and Methods in Physics Research, A

Abstract

The MUNU detector was designed to study neutrino-electron elastic scattering at low energy. The central component is a Time Projection Chamber filled with CF4 gas, surrounded by an anti-Compton detector. The experiment was carried out at the Bugey (France) nuclear reactor. In this paper we present the final analysis of the data recorded at 3 bar and 1 bar pressure. Both the energy and the scattering angle of the recoil electron are measured. From the 3 bar data a new upper limit on the neutrino magnetic moment was derived. At 1 bar electron tracks down to 150 keV were reconstructed, demonstrating the potentiality of the experimental technique for future applications in low energy neutrino physics., Comment: 7 pages, 8 figures; p. 3: changed definition of fidet

Abstract

We built a low background detector to measure the νee− elastic cross section at low energy. The detector has been installed close to a nuclear reactor in Bugey and it is running since almost one year. After having reduced the electron background by more than 2 orders of magnitude we are now taking data to be sensitive to a neutrino magnetic moment in the region below 10−10 Bohr magnetons.

Abstract

We are interested in the organisational changes in identity, brought about by the juxtaposition of paper and electronic media in the domain of daily newspapers. We define these changes through a specific case: placing the daily newspaper Le Monde on the Internet as Web pages. Our concern is how changes in identity, related to placing a daily newspaper on-line, are understood by a «communicational reading». We explore the on-line newspaper industry using «l'approche communicationnelle» (Alex Mucchielli, 1997, 1998, 2000). This approach pays particular attention to the communication processes which define the on-line newspaper industry. Our objective is to research how the nature of journalism arises, sets itself up and evolves with the help of information and communication technologies.

Abstract

We are building a low background detector based on a gas time projection chamber surrounded by an active anti-Compton shielding. The detector will be installed near a nuclear reactor in Bugey for the experimental study of νee− scattering. We give here a general description of the experiment, and an estimate of the expected counting rate and background. The construction of the time projection chamber is described in details. Results of first test measurements concerning the attenuation length and the spatial as well as energy resolution in the CF4 fill gas are reported.
