If the case
for a muon collider as the next energy frontier machine can be made compelling,
it becomes a candidate to be added to other options for the High Energy Physics
community. However, the proton
drivers used to produce the required muon intensity are expensive and difficult,
and the decays of the large number of muons in the storage ring make experiments
extremely difficult. The key is to
produce beams with much smaller sizes so that high luminosity can be achieved
with fewer muons. Muon collider
luminosity depends on the number of muons in the storage ring and on the
transverse size of the beams in collision. As
presently envisioned, ionization cooling will not cool the beam sizes
sufficiently well to provide adequate luminosity without large muon intensities.
This project will explore a new idea to combine ionization cooling with
parametric resonances leading to beams with much smaller sizes. In
Phase I, computer simulations will be used to confirm the general analytical
predictions. Critical technical
issues will be identified for computational and experimental investigation in
Phase II.
Commercial
Applications and Other Benefits as described by the awardee:
If the new cooling system works and beam sizes can be reduced, the
requirements for muon production rates may be relaxed enough to make a future
muon collider feasible. The muon
collider could then be developed by modifying existing or future machines at
reduced costs and accelerated schedules.
