Description
We present a preliminary lattice design for a series of pulsed synchrotron rings to accelerate muon beams to their maximum collision energy at Fermilab. The rings are limited to a circumference of 15.5 km, which would allow them to fit just within the Fermilab site boundary. We wish to estimate the maximum energy that muons can be accelerated to on the Fermilab site based on a realistic lattice layout for the synchrotron chain. We consider the feasibility of beginning the synchrotron chain with Tevatron sized (6.28 km circumference) rings. To achieve high average fields, superconducting fixed field magnets are interleaved with iron-dominated magnets whose fields are rapidly ramped from negative to positive. We consider which rings in the acceleration chain benefit from using dipole and quadrupole magnets interleaved in this fashion. Multiple RF stations are required to ensure that the beam energy and the magnet fields are reasonably well synchronized and to avoid longitudinal losses due to the large synchrotron tune. We use FODO arc cells with dispersion suppressed into the RF straights. We will discuss tradeoffs between maximum energy, energy range, and muon decays.
