An induction-coil magnetometer for mid-plane measurements in spectrometer magnets

Induction-coil magnetometers are among the most common devices for measuring both static and transient magnetic fields in accelerator spectrometer magnets. Recent developments have included an induction-coil array mounted on a sledge, which is translated mid-plane of normal-conducting This device, subsequently denoted as moving fluxmeter, used to derive field homogeneity magnet center, well gradients fringe-field areas. Induction coils capture flux through surface that traced out by coil windings. A deconvolution necessary recover density from measured voltage signal. The key idea this article combine advantages small large induction optimize sensitivity function frequency domain. In way, information loss due ”blind-eye” frequencies can be avoided signals deconvoluted with ease. While design metrological characterization inspired theory rotating-coil magnetometer, needs expressed terms longitudinal spatial instead angular frequencies. Consequentially we working Fourier transforms, series periodic signals. function, i.e., convolution kernel, optimized relevant range precise layout coil-turns printed circuit board (PCB). Measurement results presented validate concept prove its respect classical design.
