Proposal of an experimental test at DA Phi NE for the low emittance muon beam production from positrons on target

We present in this paper the proposal of an experimental test at DA Phi NE of the positron-ring-plus-target scheme foreseen in the Low EMittance Muon Accelerator. This test would be a validation of the on-going studies for LEMMA and it would be synergic with other proposals at DA Phi NE after the SIDDHARTA-2 run. We discuss the beam dynamics studies for different targets inserted in a proper location through the ring, i.e. where the beam is focused and dispersion-free. The development of the existent diagnostic needed to test the behaviour of the circulating beam is described together with the turn-by-turn measurement systems of charge, lifetime and transverse size. Measurements on the temperature and thermo-mechanical stress on the target are also under study.
