Japanese hadron facility plans and future μSR
- 16 Downloads
The proposed next major science project in Japan, the high intensity 1 GeV proton accelerator with unique beam characteristics, is described here. It will supply a proton beam of more than 100 μA in either de mode or sharply pulsed mode (down to 10 ns), using a specially designed time structure conversion ring. The beam will be used for keV μ+ generation at the production target, MeV surface μ+ production and 10 MeV decay μ+ and μ− production, as well as a possible slow μ− production. All of these unique muon beams will be developed for the next generation of μSR experiments. With the development of the keV μ+ source particularly in mind, a pilot station is now under construction at UT-MSL/KEK. Possible new μSR experiments are also reviewed.
