For many facilities e.g. GSI, CoSY, J-Parc limited installation lengths requires high gradients in the region of 40kV/m. Both requirements rule out ferrite materials due to the lower maximum excitation levels and high Q-value. This request can solely be met by Finemet type cores like NANOPERM® produced by MAGNETEC. In this paper, the statistics of 22 huge cores made of NANOPERM® and measured high frequency properties are shown under free-space (FS) condition and compared with the theoretical expectation.
