You can join and analyze the data of on-going projects, or, you can write a research proposal to obtain a beam time to start a real research of your own.
Our on going projects right now are
M1437 (Hunting for negative muonium (Mu-) state in a cage-type electride C12A7) and
M1524 (muSR of electride Ca2N and spinoride RE2C),
both of which deals materials called electride, where the electron itself behaves as the negative ion of the material. This is a good playground for electron catalist or functional mateirals.
More conventinal project of magnetism or superconductivity is being planned.
