“…many of the individual components used in the cooling system, and cooling has been studied in different materials and with different beta functions. Furthermore, Monte Carlo calculations have been done to study wedge cooling using different beta functions and dispersions, and transverse cooling in lithium lenses has been simulated under a wide range of conditions [17,19,20,21].…”

We propose a six-year research and development program to develop the hardware needed for ionization cooling, and demonstrate the feasibility of using the ionization cooling technique to produce cooled beams of positive and negative muons for a muon collider. We propose to design and prototype critical sections of the muon ionization cooling channeL These sections would be tested by measuring their per formance when exposed to single incoming muons with momenta in the range 100 300 MeV Ie. The phase-space volume occupied by the population of muons upstream and downstream of the cooling sections would be measured sufficiently well to enable cooling to be demonstrated, the calculations used to design the cooling system to be tested, and optimization of the cooling hardware to be studied.

“…We present a moment description [1,2] tracking but still contains much of the physics relevant to ionization cooling. While this approach is useful in identifying promising designs, particle tracking [6,7] remains an essential step to fully validate and optimize such preliminary designs.…”

Using a moment formalism [1,2] we model beam transport in the muon collider cooling channel. This model contains much of the physics we believe to be relevant to muon cooling such as ionization energy loss and multiple scattering. Space-charge forces are currently neglected but can, in principle, be added to the model. Previously, this model has been shown to closely agree with particle tracking [1] while being significantly less computationally intensive. Presently our simulation is limited to the six-dimensional dynamics of the transverse cooling section. A matrix representation of an emittance exchange section is presented. This formulation of emittance exchange can either be ideal (conserving 6-d emittance) or can include energy loss and heating representative of the effects expected in a realistic emittance exchange section. These elements should give our model sufficient generality to enable the preliminary, yet realistic, design of a complete muon cooling channel.

“…An integrated transport + energy loss simulation is needed, and this integrated code should develop into an optimizing design tool. µ-cooling simulations are also being developed by Fernow, Kirk, MacDonald, Palmer, et al [8,9] and their contributions will be essential in developing consistent design tools.…”
