Welcome to the RIKEN-RAL Muon Facility!

Japanese Version here


Cycle 2009/5 will start on 16 February.

We have held a RIKEN Symposium (in Japanese) to report recent research progress.

The 5th ML-PAC meeting was held at RIKEN on 3 and 4 of September.

Facility Report vol.8 is available. new!


RIKEN-RAL Muon facility has been constructed by RIKEN at Rutherford Appleton Laboratory in the UK, and now part of RIKEN Nishina Center for Accelerator-based Science. The facility utilizes intense pulsed proton beam provided by the ISIS synchrotron accelerator. Thanks to an unique superconducting solenoid in our beam line, the facility produces the world's strongest source of backward decay pulsed mu+ or mu- in the momentum range from 20 MeV/c to 120 MeV/c as well as surface mu+ at 30MeV/c. A pulsed magnetic kicker split are used to split double-pulsed structure of the muon beam, enabling us to execute two experimental programs simultaneously at each channels. Important research activities such as investigations related to muon catalyzed fusion and studies of condensed matter by muon spin rotation/relaxation/resonance are now being actively pursued. A leaflet is available here.


Shown above is a schematic view of the RIKEN-RAL Muon Facility. The primary ISIS 800MeV proton beam bombards the pion production target, the created pions decay to muons in the superconducting solenoid. Muons are transported to ports 1, 2, 3 and 4.
