Description
We discuss a low energy $е^+е^-$ collider for production of the not yet discovered $\mu^+mu^-$ bound state (dimuonium). In our design we follow the Brodsky-Lebed proposal of the large-crossing-angle $е^+е^-$ intersection, when the dimuonium carries non-zero momentum and decays to $е^+е^-$ pair far apart from the beam collision region. The latter provides effective suppression of the Bhabha scattering background. We study experimental constraints and following requirements for the collider development. A preliminary layout is considered, the main parameters are obtained. The expected peak luminosity at the $\mu^+mu^-$ production threshold is $8\times10^31$. The same machine can be used for high statistic study of hadronic processes ($e^+e^-\to \pi^+pi^-$, $\pi^+pi^-\pi^0$, $\pi^0\gamma$ etc.) and search for rare processes in the center-of-mass energy range below 960 MeV.
