The MUNU detector was designed to study ν¯ee− 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 Letter 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 μeshort<9×10−11μB at 90% CL 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.
The Legnaro Lab of the Italian Institute of Nuclear Physics hosts a set of accelerators for advanced nuclear physics studies as well as for various nuclear physics applications. The first Van de ...Graaff accelerators have been followed by the new ones based on RF superconductive cavities and high intensity normal and superconductive RFQ. The new projects move on the same line: new physics and new applications.
The MUNU experiment was carried out at the Bugey nuclear power reactor. The aim was the study of ν̄ee− elastic scattering at low energy. The recoil electrons were recorded in a gas time projection ...chamber, immersed in a tank filled with liquid scintillator serving as veto detector, suppressing in particular Compton electrons. The measured electron recoil spectrum is presented. Upper limits on the neutrino magnetic moment were derived and are discussed.

We report on the performance of a 1m3 Time Projection Chambers filled with CF4 at 3 bar, immersed in liquid scintillator and viewed by photomultipliers. Particle detection, event identification and ...localization achieved by measuring both the electric current and the scintillation light are presented. Particular features of α particle detection are also discussed. Finally, the 54Mn photopeak, reconstructed from the Compton scattering and recoil angle is shown.

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 CF

Roeckl, The Euroschool Lect. on Phys. with Exotic Beams, Vol. II, Springer (2006) facility for the production of neutron-rich radioactive nuclei by uranium fission. RIBs will be produced by proton induced fission on a UCx multi foil direct target at a rate of 10
13 fps, more than one order of magnitude larger than the currently available beam intensities. The recent developments on the production, ionization and acceleration of RIBs at SPES are hereafter presented.

An electronic device has been realized which provides the total number of firing limited streamer tubes (LST) in different sectors as well as in the whole detector. These numbers are available a few ...microseconds after the read-out of the LST front-end electronics and can be used for trigger purposes.
