PKA energy spectra and primary damage identification in amorphous silica under different neutron energy spectra

Amorphous silica is a key component in windows of heating systems in magnetic fusion reactors and the final focusing of lasers in inertial confinement fusion. Primary knock-on atoms (PKA) energy spectra will be obtained using the SPECTER code for different neutron energy spectra. From those data a systematic analysis of primary damage will be obtained using the TRIM code for high energy recoils, in order to get distribution of cascades and subcascades for these recoil energies to different densities of amorphous silica.
