Well balanced pick-up assembly for double pulsed magnetic field apparatus

Abstract

The generation of high magnetic pulsed fields involves several technological challenges. State-of-the-art field
peak intensities can be achieved by means of double-coil systems and, as for other configurations, a special
pick-up system is required to clean the signal from spurious components and artifacts. However, the design of a
well-balanced pick-up for double-coil systems is not a trivial task because of the different mutual inductance of
the two field coils. In general the pick-up can be optimized for one coil only, but not for both.Here we present a
new pick-up concept specifically aimed at solving this problem, based on an active compensation bridge and a
special compensating coil located outside field-generating coils. Besides yielding a good balance of the signal
over all pulse duration, a further advantage is an additional increase in the signal-to-noise ratio.
