A. Anastasi et al', "The Laser Control of the Muon (g-2) experiment at Fermilab"

Abstract

The Muon g-2 Experiment at Fermilab is expected to start data taking in 2017. It will
measure the muon anomalous magnetic moment, aµ = (gµ − 2)/2 to an unprecedented precision: the goal is 0.14 parts per million (ppm). The new experiment will require upgrades of detectors, electronics and data acquisition equipment to handle the much higher data volumes and slightly higher instantaneous rates. In particular, it will require a continuous monitoring and state-of-art calibration of the detectors, whose response may vary on both the millisecond and hour long timescale.
The calibration system is composed of six laser sources and a light distribution system will provide short light pulses directly into each crystal (54) of the 24 calorimeters which measure energy and arrival time of the decay positrons. A Laser Control board will manage the interface between the experiment and the laser source, allowing the generation of light pulses according to specific needs including detector calibration,
study of detector performance in running conditions, evaluation of DAQ performance.
Here we present and discuss the main features of the Laser Control board.
