This is attached to the electromagnet in order to make measurements by low frequency modulation (80Hz) of the magnetic field. Using low frequency modulation, rapid passage conditions can be avoided.
|Field modulation width
|0.2 μT to 2 mT
|Type of modulation
Applicable instrument(Not applicable if sub pole pieces are already fitted)
Measurement of samples with long relaxation time (T1)
Apply field modulation for cavities without internal modulation coil.
