Why a muon collider?

A muon collider is the only near-future technology to allow exploration of the 10 TeV scale and beyond.

Exploration of the energy frontier has led to some of the most fundamental discoveries of the last century. To continue this exploration into the future, a paradigm shift is needed. We cannot simply build larger and larger versions of the same ee and pp machines: constraints from cost, available land, and energy efficiency put a cap on the reach of these machines. 

A muon collider is an affordable, compact, and energy efficient solution that provides the potential to explore energies well beyond the 10 TeV scale. But to realize this vision in the future, research and development is needed today. 

Why now?

Recent breakthroughs and the need for a global collider future make now the right time to act.

Over the last decade, major breakthroughs in ionization cooling, target technology, high field magnets, and precision timing detectors have turned a muon collider from a far-off dream to a tangible possibility. 

Piggybacking off of planned upgrades for Fermilab's proton injector, there is an opportunity to build a Fermilab-sited muon collider, bringing the energy frontier back to US soil. 

Best estimates for a technically limited timescale put first muon collider physics at 2045, making a muon collider by far the fastest path to energies beyond the LHC. Without adequate funding today, that timescale will expand, creating large gaps between energy frontier machines, leading to loss in expertise and personnel. With dedicated R&D today, we can re-invigorate the US accelerator program, and inspire particle physicists for decades to come.

 What's next?

Accelerator Design

Recent progress in overcoming technical challenges posed by the muon's lifetime has generated a great deal of excitement for particle physicists.


Reconstruction Software

Great progress has been made towards identifying signals and reject muon beam-induced background, but there's still much more to do. Check out software packages here, and join the meetings hosted by IMCC.

IMCC

The International Muon Collider Collaboration (IMCC) is hosted by CERN and securing resources to complete a Muon Collider Design Study before the next European Strategy Report.


Physics Studies

Combining energy and precision, a muon collider provides unprecedented physics reach. See the Snowmass Muon Collider Forum report and Energy Frontier report for more.
