Magnet


A magnet with a field of ~70 Gauss is employed to control the field and hence the MuSR effects.

Two different locations of the magnet coil were investigated.

i) a small magnet around the hydrogen pressure vessel (easier to handle)

ii) a large magnet between the outside electron wire chamber and the scintillator hodoscope (less scattering)
