Ultra-slow muons

It is the purpose of this section to show that (iSR spectroscopy can be adapted to a wide variety of experimental conditions. We have mentioned earlier the special features offered by a pulsed muon beam, such as the synchronous applications of light and/or RF pulses. Many new adaptations of p,SR spectroscopy are still under active development and the field becomes richer and more versatile constantly. The most exciting new prospect is probably the ultra-slow muon beam which will be discussed briefly in subsect. 2.7.5. [Pg.81]

The group at KEK (Nagamine et al. 1995, Miyake et al. 1995, 1997) produces ultra-slow muons by first generating thermal muonium at the surface of a hot tungsten target placed in the pulsed primary proton beam. They then resonantly ionize the muonium by synchronously pulsed intense light from an UV laser. The resulting thermal p" are electrostatically collected and form the pulsed ultra-slow muon beam with about 50% of muon spin polarization preserved. The p spin is adjusted perpendicular to the beam axis. Test spectra have been obtained for a lOnm Au sample. Intensity is still very low. [Pg.88]

In summary, ultra-slow muon beams are now available to the experimenter. This expands pSR to the acute research fields of surface-, interface- and multilayer physics. Magnetic multilayers are of comse of prime interest in lanthanide magnetism. [Pg.88]
