Welcome to the Muon Cooling Homepage at MPI Munich
Muon beam cooling is crucial for the feasibility
of a muon collider. The nominal cooling scheme for colliders is based
on ionization cooling, and for muons this is done at the energy range
of 200 MeV. It is important to keep the muons at or above this energy becasuse
of the short muon lifetime. However, there are several problems with this
We are investigating the possibility of bringing
the muons down to keV or sub keV energies and then reaccelerating them.
An equilibrium energy can in principle be achieved if the particles are subject
to a constant accelerating force once they are in this energy range. This
leads to drastically reduced phase space for the muon beam.
- The cooling channels are technically complicated.
- The cooling achieved is only in the transverse
- The total cooling may not approach desired
