Intense muon sources have been discussed as a starting point for very
high energy colliders and even more in recent years as a source of very
intense and well-collimated neutrino beams.
This working group should identify, but clearly
distinguish, the main accelerator physics aspects of both the Muon Collider and the Neutrino Source. Even
more, it is crucial to understand for the high energy physics community, how
much a Neutrino Source represents a first step to a muon collider and what are
the additional burdens. Given the variety of technologies that require
R&Dmakes it necessary to have the group present a risk assessment of the
various subcomponents, their R&D goals and the time scale on which the R&D
could be realized. The more recent refocus of the
collaboration towards Neutrino Sources should reflect in the main topics of
the discussion.
The different approaches: CERN, KEK-JAERI, and the Muon Collaboration
(including the Fermilab and Brookhaven locations), should be compared in
performance, risk and (if possible) schedule.
A discussion on whether a Muon Cooling experiment is necessary and/or viable
is absolutely required and should be presented by the group.
For
the Muon Colliders, the technical performance, especially for a low energy
(Higgs collider) machine should be adressed. Technical performance (power
consumption, risk assessment, luminosity, etc ) should be compared to linear
colliders in the same energy range.
Input here will be required from the High Energy physicists to define the
measure of performance for these two concepts (MC, LC). For the long-term
R&Dthe advantages compared to e+e- accelerators should be worked out and
quantified as much as possible.
