“…In muon collider scenarios, emittances as small as 25μ (transverse, rms, normalized) are required to ensure high luminosity at multiTeV energies [1]. Ionization cooling is used to reduce transverse emittances, following the cooling equation:…”

A high-energy muon collider scenario requires a final cooling system that reduces transverse emittance to ~25 microns (normalized) while allowing longitudinal emittance increase. Ionization cooling using high-field solenoids (or Li Lens) can reduce transverse emittances to ~100 microns in readily achievable configurations, confirmed by simulation. Passing these muon beams at ~100 MeV/c through cm-sized diamond wedges can reduce transverse emittances to ~25 microns, while increasing longitudinal emittances by a factor of ~25. Implementation will require optical matching of the exiting beam into downstream acceleration systems.

“…In the longer term, µ + µ − collisions could also be envisioned [76][77][78], once the considerable technological challenges related to muon production, cooling, acceleration, and decay backgrounds, have been solved. The reduced synchrotron radiation loss from muons -by a factor 10 9 with respect to electrons -would then enable the construction of circular colliders either with much smaller radii at low energies, or with much higher design energies, typically 6 to 14 TeV.…”

“…The first section is where the protons collide with a mercury jet target to produce pions. They are collected by magnets that guide the pions into a beam [26,27]. Then, they decay into muons and neutrinos producing a strong beam of neutrinos, that might be used by other experiments, and a beam of muons with high initial beam emittance.…”

To explore the new energy frontier, a new generation of particle accelerators is needed. Muon colliders are a promising alternative, if muon cooling can be made to work. Muons are 200 times heavier than electrons, so they produce less synchrotron radiation, and they behave like point particles. However, they have a short lifetime of 2.2 µs and the beam is more difficult to cool than an electron beam. The Muon Accelerator Program (MAP) was created to develop concepts and technologies required by a muon collider. An important effort has been made in the program to design and optimize a muon beam cooling system. The goal is to achieve the small beam emittance required by a muon collider. This work explores a final ionization cooling system using magnetic quadrupole lattices with a low enough β region to cool the beam to the required limit with available low Z absorbers. Dr. Alakabha Datta, and Dr. Hailin Sang, for all of the guidance. Also, many thanks to Dr. Terrence Lee Hart for his help. His discussions were valuable and his guidance in the simulation code was essential for this work. iv
