Magnetic Diagnostics

EHT integrators are designed to simplify magnetic field measurements. Pickup coils are widely used by the fusion science and plasma physics communities for precision measurements of magnetic fields. The voltage across the coil is proportional to the time derivative of the magnetic field. Analog integrators produce an output signal that is equal to the integral of the input signal. These off-the-shelf integrators remove the complexity of making stable integrators and allow researchers to focus on the science rather than the electronics.
