Abstract:
We have studied numerically a heavy beam loading and instabilities in the 8 GeV Fermilab Accumulator ring in frames of the µ2e (muon-to-electron conversion) experiment. A numerical model based on Fourier expansion of the beam current has been introduced and beam dynamics during tens thousands turns in the Accumulator were simulated. A cross-checking of beam loading has also been done with other codes and with analytical formulae, demonstrating an excellent agreement. The results of simulations put limitations on the cavity shunt impedance and the RF time wave-form to ensure the necessary bunch quality for µ2e research program.
