The MEG II experiment was designed to improve by an order of magnitude the sensitivity of reached by MEG on the branching ratio of the decay. The resolution of the positron timing is improved by using a segmented pixelated Timing Counter (pTC) where each counter is read independently. The pTC was commissioned in several engineering runs as well as in the first year of physics run (2021) at the E5 beam line at PSI. Degradation of time resolution performance is observed and a program of partial upgrading the pTC is ongoing.

Abstract
The MEG II experiment was designed to improve by an order of magnitude the sensitivity of reached by MEG on the branching ratio of the decay. The resolution of the positron timing is improved by using a segmented pixelated Timing Counter (pTC) where each counter is read independently. The pTC was commissioned in several engineering runs as well as in the first year of physics run (2021) at the E5 beam line at PSI. Degradation of time resolution performance is observed and a program of partial upgrading the pTC is ongoing.File in questo prodotto:
