“…Typically, at c.m.e. of 6 TeV, two single bunches of 2×10 12 muons, each of transverse dimensions of ∼1.5 µm, collide at a rate of ∼50 kHz, providing a peak luminosity largely exceeding 10 34 cm −2 s −1 [4][5][6][7]. One of the main technical limitations to obtain high luminosity comes from the difficulty in producing highly collimated muon beams.…”

Lepton Flavor Violating (LFV) processes are clear signals of physics beyond the Standard Model. We investigate the possibility of measuring this kind of processes at present and foreseeable future muon-electron colliders, taking into account present day bounds from existing experiments. As a model of new physics we consider a Z’ boson with a Ut(1) gauge symmetry and generic couplings. Processes that violate lepton flavor by two units seem to be particularly promising.

“…• Higgs Factory [44,45,46] [46,47,48]: if warranted by LHC results, a multi-TeV MC, with an ultimate energy reach up to roughly 10 TeV, likely offers the best performance and least cost and power consumption of any lepton collider operating in the multi-TeV regime. The nuSTORM proposal [41] is an ideal entry level short-baseline NF, which does not require any new technology development before construction (Fig.…”

“…The MC parameters for collider rings at 1.5 TeV, 3 TeV [47] and 6 TeV [48] are summarized in Table 3. Assuming that the main dipoles are 10 T superconducting magnets, the respective circumferences of 2.5, 4.5 and 6 km allow multiple collisions in two detectors for roughly 1000 turns during the lifetime of the muon beams.…”

“…The collider performance is determined by the intensity and brightness of the muon source. Table 5 summarizes key parameters of three options for a 14 TeV MC in the LHC tunnel with a beam-beam lifetime in collision of 146 ms: the first one adapts the existing 24 GeV CERN PS source, the second requires a new 8 GeV linac and storage ring [48], while the third is based on the threshold production of μ + μas proposed in the LEMMA scheme.…”

The potential of muon beams for high energy physics applications is described along with the challenges of producing high quality muon beams. Two proposed approaches for delivering high intensity muon beams, a proton driver source and a positron driver source, are described and compared. The proton driver concepts are based on the studies from the Muon Accelerator Program (MAP). The MAP effort focused on a path to deliver muon-based facilities, ranging from neutrino factories to muon colliders, that could span research needs at both the intensity and energy frontiers. The Low EMittance Muon Accelerator (LEMMA) concept, which uses a positron-driven source, provides an attractive path to very high energy lepton colliders with improved particle backgrounds. The recent study of a 14 TeV muon collider in the LHC tunnel, which could leverage the existing CERN injectors and infrastructure and provide physics reach comparable to the 100 TeV FCC-hh, at lower cost and with cleaner physics conditions, is also discussed. The present status of the design and R&D efforts towards each of these sources is described. A summary of important R&D required to establish a facility path for each concept is also presented.

“…The momentum acceptance needs to be improved from 6% to 10% by adding chromatic correction with sextupole magnet pairs to improve the transmission to 85%. Reverse emittance exchange with septa [45] and/or wedges [46] might then be used to decrease transverse emittance from 100 to 25 µm at the expense of longitudinal emittance to allow a √ s = 6 TeV lepton collider [95].…”

Final Cooling for a Muon Collider

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
