Degradation of polyimide under the irradiation with swift heavy ions
This study concentrates on radiation-induced ageing effects of polymers planned as insulating materials in the rapidly cycling superconducting magnets presently being developed for the FAIR facility. Although beam control and minimization of beam losses will be a major issue, the exposure of insulating parts (e.g. polyimide, polyetherimide, and glassenforced epoxy-compounds) of various accelera...
متن کاملDislocation loop formation by swift heavy ion irradiation of metals.
A coupled two-temperature, molecular dynamics methodology is used to simulate the structural evolution of bcc metals (Fe and W) and fcc metals (Cu and Ni) following irradiation by swift heavy ions. Electronic temperature dependent electronic specific heat capacities and electron-phonon coupling strengths are used to capture the full effects of the variation in the electronic density of states. ...
متن کاملMechanical degradation of polyimide induced by swift heavy ion irradiation
In the new superconducting FAIR magnets, polyimide films (Kapton) will be used as insulator. During operation, the material is exposed to high-dose radiation and it has to withstand enormous mechanical forces induced by the magnet field ramping. For better lifetime estimation, this study investigates radiation-induced degradation of the mechanical properties of Kapton by tensile strength measur...

متن کاملModel for nucleation of dislocation loops in graphite under irradiation with swift heavy ions
Irradiation of highly oriented pyrolytic graphite (HOPG) with swift heavy ions demonstrated that damage of the material is originated by electronic energy loss [1]. To support further analysis of experimental data from Raman spectroscopy, electron microscopy, X-ray scattering, etc., some assumptions about damage structure are necessary. It is reasonable to assume that not only primary Frenkel d...
