NMR calibration of other mappers
For magnets with complex fields, such as quadrupoles and wigglers, the measurements are performed using a variety of other techniques: Hall devices, rotating coils, moving coils, moving wires, vibrating wires, pulsed wires, etc. All these techniques have one thing in common: they all need to be calibrated in a reference magnetA magnet used for calibrating a magnetometer. Reference magnets are often controlled or even regulated by an NMR teslameter. controlled by an NMRNuclear Magnetic Resonance.

Space is at a premium in the beamline or reference magnetA magnet used for calibrating a magnetometer. Reference magnets are often controlled or even regulated by an NMR teslameter., so Metrolab has developed a rangeThe range of a probe is defined by the minimum and maximum field strength it can measure. On an instrument,... of miniature probes and gradientIn this context, gradient refers to the spatial variation of the magnetic field. compensation coils that allow probes to be squeezed into almost any installation. Decades of testing and use in these high-radiation environments allow us to build radiation-hard probes and advise you how to get years – or decades – of trouble-fee use in hard-to-reach placements.
