The efficiency of gas-filled surge arresters in the environment contaminated by non-ionizing radiation of fusion reactors
Published 2022-01-01“…For the efficiency of the flexible model, it was found to be slightly less than 40% (and to be achieved by the application of alpha particle radiation). Since neither of these efficiencies guarantee reliable operation of the gas-filled surge arrester, it was concluded that essential electronics in the vicinity of the fusion generator must be protected. …”
