Extracting the coefficients of Fourier–Bessel series, known as pseudo-multipoles or generalized gradients, from magnetic measurements accelerator magnets involves technical and mathematical challenges. First, a novel design short, rotating-coil magnetometer is required that does not intercept any axial field component magnet. Moreover, displacing short magnetometers, step-by-step along magnet axis, yields convolution local multipole errors sensitivity (test function) induction coil. The...
