Cryogenic Magnetic Field Monitor

We need to be able to measure the magnetic field gradients in the measurement cells, but typical magnetic sensors use magnetic materials and must be no closer than several feet away.
By inverting Maxwell’s equations we can determine the field inside the measurement cells by extrapolation of externally measured fields.
The Cryogenic Magnetic Field Monitor was constructed using the same spaceframe construction techniques as the primary coils in the Magnet Module and is now complete.
