Secondary Particle Production and Capture for Muon Accelerator Applications
Intense pulsed muon beams are required for
projects such as the Neutrino Factory and S.J. Brooks (CCLRC/RAL/ASTeC)
Muon Collider. It is currently proposed to
produce these from a high-Z target using a multi-megawatt proton driver. This paper examines the effect of proton
energy on the yield and distribution of particles produced from tantalum and mercury, with further analysis
using a tracking code to determine how these distributions will behave downstream, including a breakdown of loss
mechanisms. Example ’muon front end’ lattices are used from the UK Neutrino Factory design.
Design and Expected Performance of the Muon Beamline for the Muon Ionisation Cooling
Experiment
It is proposed to install a Muon Ionisation
Cooling Experiment (MICE) at the ISIS facility,
at Rutherford Appleton Laboratory
(RAL). This experiment will be the first
demonstration of ionisation cooling as a

means to reduce the large transverse emittance of the muon beam, produced during the early stages of a Neutrino
Factory. In order to permit a realistic demonstration of cooling, a beam of muons must be produced, possessing
particular qualities, notably in emittance and momenta. This paper describes the current design for the muon
beamline, outlining issues particular to the needs of the MICE experiment, and discusses its expected performance.
Simulation of MICE Using G4MICE
In the Muon Ionisation Cooling Experiment
(MICE), muons will be fired one by one
through one or two cooling cells. The experiment
will be used to optimise simulation

of an ionisation cooling channel for a future Neutrino Factory. This is achieved by measuring the position of each
muon in six-dimensional phase space and examining the behaviour of muons collected into bunches offline. The experiment
will be run with a number of different input beams, magnet configurations, RF configurations and absorber
types. We present the simulated detector and cooling performance of the MICE cooling channel using the G4MICE
simulation code for a range of configurations. We detail the simulation of engineering, field and detector models and
examine the implications for the cooling efficacy and measurement.
