First results of the trip-t based T2K front end electronics performance with GM-APD

Proceedings of Science (2007)

Authors:

A Vacheret, M Noy, M Raymond, A Weber

Abstract:

The TRIP-t front end board (TFB) will read out Geiger-mode multi-pixel Avalanche Photo-Diodes (GM-APD) in several T2K detector systems. We report the first tests of the TFB electronics with GM-APD. Measurements of GM-APD charge spectra, energy and time resolution have been performed. Individual channel voltage trimming circuit functionality has also been tested. These results indicate very good performance of the TFB prototype with both 400 and 100 pixels GMAPD from Hamamatsu photonics. © Copyright owned by the author(s).

The front end readout system for the T2K-ND280 detectors

IEEE Nuclear Science Symposium Conference Record 3 (2007) 1984-1991

Authors:

A Vacheret, S Greenwood, M Noy, M Raymond, A Weber

Abstract:

The Tokai-to-Kamioka (T2K) long baseline neutrino experiment goal is to measure vμto ve oscillation parameters using near (280 m) and far (295 km) detectors from the beam origin in the J-PARC accelerator in Tokai. The far detector will be Super-Kamiokande. The 280 m near detectors complex (ND280) contain a number of scintillator based sub-detectors and a beam monitor. Approximately 54,000 scintillator bars will be read out by Multi-Pixel Photon Counter devices (MPPC) via wavelength shifting fibres. It will be the first time this novel type of photo-sensor is used on such a large scale. The front end readout system for the MPPC uses Fermilab Trip-t chips mounted on Trip-t Front end Boards (TFB). The TFB design and measured performance in conjunction with MPPC photo-sensors are presented. © 2007 IEEE.

Abstract:

The velocity of a ∼3GeV neutrino beam is measured by comparing detection times at the near and far detectors of the MINOS experiment, separated by 734 km. A total of 473 far detector neutrino events was used to measure (v-c)/c=5.1±2.9×10-5 (at 68% C.L.). By correlating the measured energies of 258 charged-current neutrino events to their arrival times at the far detector, a limit is imposed on the neutrino mass of mν<50MeV/c2 (99% C.L.). © 2007 The American Physical Society.
