Fine tuning of electron beam crosslinking of electrical cables and wires by three-dimensional Monte Carlo modeling

In this paper, the validity of the dose ratio criterion to define the optimum processing conditions for electron crosslinking of electric cables and wires is investigated. The energy values obtained by different calculation procedures are correlated to the results obtained by simulation with a realistic three-dimensional Monte Carlo model in conjunction with an optimization scheme to define the best dose uniformity in the cable isolation. The study shows that the dose ratio criterion does not provide the best dose uniformity, since the optimum electron beam energy value is usually underestimated.
