The Mice Muon Beamline and Host Accelerator Beam Bump

The international Muon Ionization Cooling Experiment (MICE) is
designed to provide a proof of principle of the technique of ionization
cooling, the reduction of the phase space of a muon beam exploiting
ionization energy loss in absorbers. Subsequent re-acceleration is
then provided by RF cavities ("sustainable cooling").  Ionization
cooling represents an important step toward future facilities based on
stored muons beams, such as a future Neutrino Factory or Muon
Collider.

The MICE Muon Beam begins with the decay of pions produced by a
cylindrical titanium target dipped into the circulating proton beam of
the 800 MeV ISIS synchrotron at the Rutherford Appleton Laboratory,
U.K.  This generates a pion shower which is captured and subsequently
decays producing the muon beam. A secondary effect of the MICE target
is to cause an increase in the number of protons lost from the ISIS
beam, known as beam loss.  

An overview is presented here of the MICE Muon Beamline, including 
the results of a study of the effect of dynamically raising the vertical
position of the ISIS beam (a 'beam bump'), in the vicinity of the
MICE target.
