Description
Muonium is the bound state of an antimuon with an electron (mu+e-). Muonium is an ideal tool to perform precision measurements of fundamental parameters. This poster presents our ideas to develop a high-brightness muonium source at the Paul Scherrer Institut (PSI). The muonium beam will be produced by deflecting a slow, high-brightness muon beam (currently under development by muCool collaboration) into the vertical direction and letting it impinge on a thin film of superfluid helium at 100 mK. Inside the superfluid helium muonium is formed with high efficiency and once it diffuses to the surface emitted into vacuum as a beam. Such a high-brightness muonium source enables various interesting measurements as , e.g., the detection of the 1s-2s energy interval of muonium or the gravitational interaction of muonium – a test of the gravitational interaction of antimatter and 2nd generation particles.
