Popovic, RF Cavities Loaded with Dielectric for Muon Facilities RF CAVITIES LOADED WITH DIELECTRIC FOR MUON FACILITIES
Abstract This paper discusses RF cavities loaded with dielectric material that could be used in various muon collider facilities. Most of the existing pill-box cavity designs are too large in diameter to fit efficiently in the current cooling lattice designs. The paper describes novel compact dielectric loaded RF cavities designs that fit efficiently in muon cooling lattices and allow multifrequency cavity designs in the same size cavity by changing the dielectric constant or size. The paper describes the designs of 400 and 800 MHz cavities for the (HCC) helical cooling channel. In addition to the use of the dielectric to reduce the radial size of gas-filled cavities in helical cooling channels, dielectric-loading has the potential use in vacuum cavities for suppression of dark current emission. Cavities that can be used for the phase rotation channel in the front end of a muon collider or neutrino factory are also presented
The Case for a Muon Collider Higgs Factory
We propose the construction of a compact Muon Collider Higgs Factory. Such a
machine can produce up to \sim 14,000 at 8\times 10^{31} cm^-2 sec^-1 clean
Higgs events per year, enabling the most precise possible measurement of the
mass, width and Higgs-Yukawa coupling constants.Comment: Supporting letter for the document: "Muon Collider Higgs Factory for

Status of Muon Collider Research and Development and Future Plans
The status of the research on muon colliders is discussed and plans are
outlined for future theoretical and experimental studies. Besides continued
work on the parameters of a 3-4 and 0.5 TeV center-of-mass (CoM) energy
collider, many studies are now concentrating on a machine near 0.1 TeV (CoM)
that could be a factory for the s-channel production of Higgs particles. We
discuss the research on the various components in such muon colliders, starting
from the proton accelerator needed to generate pions from a heavy-Z target and
proceeding through the phase rotation and decay ()
channel, muon cooling, acceleration, storage in a collider ring and the
collider detector. We also present theoretical and experimental R & D plans for
the next several years that should lead to a better understanding of the design
and feasibility issues for all of the components. This report is an update of
the progress on the R & D since the Feasibility Study of Muon Colliders
presented at the Snowmass'96 Workshop [R. B. Palmer, A. Sessler and A.
