A multi-TeV muon collider offers a spectacular opportunity in the direct exploration of the energy frontier. Offering a combination of unprecedented energy collisions in a comparatively clean leptonic environment, a high energy muon collider has the unique potential to provide both precision measurements and the highest energy reach in one machine that cannot be paralleled by any currently available technology. The topic generated a lot of excitement in Snowmass meetings and continues to attract a large number of supporters, including many from the early career community. In light of this very strong interest within the US particle physics community, Snowmass Energy, Theory and Accelerator Frontiers created a cross-frontier Muon Collider Forum in November of 2020. The Forum has been meeting on a monthly basis and organized several topical workshops dedicated to physics, accelerator technology, and detector R&D. Findings of the Forum are summarized in this report.

The timeline for power and POT delivery is laid out in Figure 1 compared to the timeline if no improvements were made beyond those of the PIP-II Project.Taking the roughly estimated cost of the Main Injector cycle time reduction and reliability improvements and combining it with the cost ranges of the mid-capability RCS or SRF Linac option produces an expected cost range of $1,000M to $2,500M for the ACE plan to be executed over the 2020's and 2030's. Note this is the full cost and does not take into account international contributions which were substantial for the PIP-II Project.The first component of the ACE plan, the Main Injector modifications, are critical to improve the complex's reliability. The Main Injector cycle time reduction will significantly boost power to LBNF in a timely way, but this extra power at 120 GeV is at the expense of power available at 8 GeV. The Booster replacement is needed to provide the extra power and flexibility at all energies. Overall the ACE program will provide proton spigots to serve experiments exploring neutrinos, the dark sector, dark matter, CLFV, as well as free-energy for new ideas.The Fermilab Booster has served the accelerator complex for 50 years, but it is not capable of serving the laboratory for the next 50 years. A Booster replacement will be needed for its superior capacity, capability, and reliability. The ACE plan delivers a timely, higher POT to LBNF than PIP-II alone could provide, and a Booster Replacement that will provide the needed capacity, capability, and reliability for a broad and diverse program of experiments.Looking ahead toward the vision of a multi-TeV collider based at Fermilab, the Booster replacement could provide an essential first step towards an accelerator complex capable of serving as the front end of such a collider. 7.6.2 Additional Technical Considerations .

Experimental activities involving multi-TeV muon collisions are a relatively recent endeavor. The community has limited experience in designing detectors for lepton interactions at center-of-mass energies of 10 TeV and beyond. This review provides a short overview of the machine characteristics and outlines potential sources of beam-induced background that could affect the detector performance. The strategy for mitigating the effects of the beam-induced background on the detector at $\sqrt{s}=3$ TeV is discussed with a focus on the machine–detector interface, detector design, and implementation of reconstruction algorithms. The physics potential at this center-of-mass energy is evaluated using a detailed detector simulation that incorporates the effects of the beam-induced background. This evaluation concerns the Higgs boson couplings and the Higgs field potential sensitivity, which then are used to obtain confidence on the expectations at 10 TeV. The physics and detector requirements for an experiment at $\sqrt{s}=10$ TeV, outlined here, form the foundation for the initial detector concept at that center-of-mass energy.
