Abstract: The new Muon g-2 experiment at Fermilab (E989) will measure the muon anomaly a𝜇 = (g𝜇 -2)/2 to an
uncertainty of 16 x 10−11 (0.14 ppm). The experiment is running with a positive muon beam. The decay positrons
are detected by 24 electromagnetic calorimeters placed on the inner radius of the magnetic storage ring. As the
gain fluctuation of each calorimeter channel must be corrected to a few parts in 104, a state-of-art laser calibration
system has been realized which provides short laser pulses to the calorimeters. The monitoring of these light
signals is done by specific photo-detectors read by a specialized Monitoring Electronics, which is organized in
devoted crates and performs the full data acquisition of the calibration signals starting from pre-amplification,
then digitization and finally transfer of the information. Here we describe few key elements of the whole system,
namely the single readout channel of the Monitoring Board.
