An alternative production method, Low Emittance Muon Accelerator (LEMMA) uses a positron beam impinging on a fixed target to produce muon pairs from the electron-positron annihilation process at the threshold centre-of-mass energy. The resulting beam does not need the cooling stage, but suffers from the very low muon-production cross section, making it challenging to achieve high

Collider and the CLIC experiment, followed by the update of the European strategy for particle physics, in which it was recommended to initiate an international design study of a Muon Collider targeting centre-of-mass energies close to 10 TeV.

This provides the unique combination of a high centre-of-mass energy and a clean collision environment

Talks were proceeding in 2009. The first dedicated design of the accelerator complex and detector design for the centre-of-mass energies up to 3 TeV was developed within the
American Muon Accelerator Program (MAP) during 2010â2015, after which it was abandoned. Interest in the Muon Collider project
