The high-energy neutron field of the VESUVIO instrument at the ISIS facility has been characterized using the technique of thin-film breakdown counters (TFBC). The technique utilizes neutron-induced fission reactions of U-nat and Bi-209 with detection of fission fragments by TFBCs. Experimentally determined count rates of the fragments are approximate to 50% higher than those calculated using spectral neutron flux simulated with the MCNPX code. This work is a part of the project to develop Chiplr, a new dedicated facility for the accelerated testing of electronic components and systems for neutron-induced single event effects in the new Target Station 2 at ISIS. The TFBC technique has shown to be applicable for on-line monitoring of the neutron flux in the neutron energy range 1-800 MeV at the position of the device under test (DUT).
