What is recorded here?
Aritome and colleagues combined thermal-muonium production, laser ionization and electrostatic extraction with a radiofrequency quadrupole to accelerate positive muons to 100 keV. Time-of-flight signals appeared with both resonant laser excitation and radiofrequency power, and quadrupole scans measured the transverse beam emittance. The reported horizontal and vertical normalized emittances were about 0.85 and 0.32 pi millimetre milliradian, respectively, more than two orders of magnitude below simulated incoming-beam values.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
This was a low-rate demonstration of positive-muon acceleration after cooling, distinct from earlier acceleration of negative muonium ions and from MICE ionization cooling. Emittance reduction compares measured outgoing values with a simulated incoming beam and includes strong particle losses and selection. Longitudinal phase space was not diagnosed. High-intensity beams, higher-energy acceleration, precision magnetic-moment measurements and proposed colliders were future applications in this paper.
