Accelerator system for the PRISM based muon to electron conversion experiment
The next generation of lepton flavor violation experiments need high
intensity and high quality muon beams. Production of such beams requires
sending a short, high intensity proton pulse to the pion production target,
capturing pions and collecting the resulting muons in the large acceptance
transport system. The substantial increase of beam quality can be obtained by
applying the RF phase rotation on the muon beam in the dedicated FFAG ring,
which was proposed for the PRISM project.This allows to reduce the momentum
spread of the beam and to purify from the unwanted components like pions or
secondary protons. A PRISM Task Force is addressing the accelerator and
detector issues that need to be solved in order to realize the PRISM
experiment. The parameters of the required proton beam, the principles of the
PRISM experiment and the baseline FFAG design are introduced. The spectrum of
alternative designs for the PRISM FFAG ring are shown. Progress on ring main
systems like injection and RF are presented. The current status of the study
and its future directions are discussed.Comment: Studies performed within the PRISM Task Force initiativ
Status of the PRISM FFAG Design for the Next Generation Muon-to-Electron Conversion Experiment
The PRISM Task Force continues to study high
intensity and high quality muon beams needed for next
generation lepton flavour violation experiments. In the
PRISM case such beams have been proposed to be
produced by sending a short proton pulse to a pion
production target, capturing pions and performing RF
phase rotation on the resulting muon beam in an FFAG
ring. This paper summarizes the current status of the
PRISM design obtained by the Task Force. In particular
various designs for the PRISM FFAG ring are discussed
and their performance compared to the baseline one, the
injection/extraction systems and matching to the solenoid
channels upstream and downstream of the FFAG ring are
presented. The feasibility of the construction of the
PRISM system is discussed
