| contents | True muonium ($μ^+μ^-$) is one of the heaviest and smallest electromagnetic bound states not containing hadrons, and has never been observed so far. In this work it is shown that the spin-1 TM state (ortho-TM) can be observed at a discovery level of significance in three months at the CERN SPS North-Area H4A beam line, using 43.7 GeV secondary positrons. In this way, by impinging the positrons on multiple thin low-Z targets, ortho-TM, which decays predominantly to $e^+e^-$, can be produced from $e^+e^- \to TM$ interactions on resonance ($\sqrt{s} \sim 2m_μ$). |
