Microstructural changes of graphite irradiated with swift heavy ions
Several methods, such as electron microscopy, scanning tunnelling microscopy (STM), X-ray diffraction, and decoration technique can be used to observe radiation damage in materials. In this work, we report microstructural changes and defect clusters induced by swift heavy ions (SHI) on graphite surfaces, visualized by scanning electron microscopy (SEM). Our studies have been performed on fine-g...
متن کاملDegradation 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 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 کاملFission Tracks Simulated by Swift Heavy Ions at Crustal Temperatures and Pressures
The fission-track dating technique is an important tool to constrain the history of samples from small archaeological specimens to large geological formations. The method is based on analyzing particle tracks produced by spontaneous fission of 238 U nuclei and accumulated over time. In laboratory experiments, fission tracks can be simulated by performing irradiations with energetic heavy ions p...
