A high performance front end for MEG II tracker

Abstract

MEG Experiment Upgrade proposes a major improvement [1] of the sensitivity in the μ →eγ decay [2]. In particular the positron tracking will be performed by means of an upgrade of MEG Drift Chamber that consists in a cylindrical wire drift chamber, with the axis parallel to the muon beam, inspired to the one used in the KLOE experiment [3]. The new tracker, currently under costruction, can achieve a resolution of 100 μm in the measurement of the drift distance to the anode wires. Improving the resolution imposes a high speed and high performance Front End Electronics for signal acquisition.
