I present a scheme to obtain a 2 to 40 GeV low emittance muon beam, not requiring cooling and within todayโs
technological resources, to be used for early commissioning of muon accelerator projects, or alternatively
dedicated muon and neutrino parameter measurements.
In particular, a muon rate of 5 ร 10^4 ๐/s in a normalized transverse emittance of 5 ๐ ๐m at 22 GeV, and
energy spread of 1 GeV obtained from ๐ (10^11 ) e+ /s on target at 44 GeV. This emittance is below the expected
results of advanced emittance cooling techniques for muons produced from protons-on-target, and represents
an alternative for the duration of complete muon cooling studies.
The scheme has beam designed to adjust the muon beam energy in the GeV energy range to the needs for
precise parameter measurements of muons and neutrinos.
Furthermore, the muon rate could be in principle increased proportionally to the availability of higher positron
rates, already foreseen for future collider projects.
