Slow control system of the muon g-2 experiment

摘要

The muon g-2 experiment (AGS E-821) will measure (alpha)(sub (mu)) = (1/2)(g (minus) 2), the anomalous magnetic dipole moment of the muon, in the world's largest superconducting solenoidal magnet. Since the magnet stores the muons during their lifetime, running the experiment is similar to running an accelerator, though on a much smaller scale and with fewer timing requirements. The slow control system for the experiment will provide real-time monitoring of the experimental parameters by means of industrial subsystems; commercial products comprise both the hardware and its interface. The industrial basis of the control system makes it quite easy to install, and provides a simple way of implementing rudimentary controls for most of the variables. Two independent networks isolate critical control functions from bookkeeping functions, yet still provide a degree of redundancy. Since commercial products form the bulk of the slow control software, there is a minimal programming requirement for tool development.
