Beam-based Diagnostics of Electric Guide Fields and Lattice Parameters for Run-1 of the Muon g-2 Storage Ring at Fermilab
AbstractA portion of the Muon g-2 Storage Ring electric system,
which provides vertical beam focusing, exhibited an
unexpected time dependence that produced a characteristic
evolution of the stored beam during Run-1 of the Muon g-2
Experiment at Fermilab (E989). A method to reconstruct
the Run-1 electric guide fields has been developed, which is
based on a numerical model of the muon storage ring and optimization
algorithms supported by COSY INFINITY. This
method takes beam profile measurements from the Muon
g-2 straw tracking detectors as input, and it produces a full
reconstruction of the time-dependent fields. The fields can
then be used for the reproduction of detailed beam tracking
simulations and the calculation of ring lattice parameters for
acceptance studies and systematic error evaluations.
