LEMMA is studying the possibility of a future muon collider where muons are produced from positrons impinging on a target. Unlike conventional muon sources, muons are produced with a very small emittance, however, a small population is produced due to the small cross section of the e+e- annihilation into muons. In order to increase the muon beam population, we are currently designing a muon...
We discuss the main factors that influence the space charge induced vortex
motion of particles within high intensity bunches (Gordon 1969)
in isochronous circular machines.
Firstly a phase slip due to deviations from strict isochronism determines
if the bunches of a specific turn are above, below or at "transition",
and hence whether stable vortex motion of the bunches is possible at...
The novel superconducting (SC) gantry has become a research hotspot with the tendency of compact proton therapy system. The footprint and weight of the gantry can be significant reduced by using SC magnets, and alternating gradient field of local achromatic bending sectors provides large momentum acceptance which means the magnetic field of SC magnets can remain fixed during tumor treatment....
