Development and commissioning of the 30 ps time resolution MEG II pixelated Timing Detector

Cattaneo P. W. Berg F. Biasotti M.

The MEG II experiment is designed to improve by an order of magnitude the sensitivity of 4.2×10−13 reached by MEG on the search for μ+→e+γ decay. A pixelated Timing Counter (pTC) has been developed to improve the time resolution by measuring the positron time information independently with several counters. We constructed and installed the pTC...

Full system of positron timing counter in MEG II having time resolution below 40 ps with fast plastic scintillator readout by SiPMs

Nishimura M. Berg F. Biasotti M.

A positron timing counter (TC) with 30–40 ps time resolution for 50 MeV/c positrons required by the MEG II experiment has been developed. We employed a highly segmented design with 512 scintillator plates (120 × 40 × 5 mm3 and 120 × 50 × 5 mm3) read out by 6-SiPM-arrays at the both ends. Pile up is reduced by the segmented design and...
