Electrospun Nanofiber Materials for High Power Target Applications [Slides]
- Fermi National Accelerator Laboratory (FNAL), Batavia, IL (United States)
Nanofiber offers promising application in future multi-megawatt targets. Since the continuum is physically discretized at micro-scale, a lot of issues like thermal stress cycles and local heat accumulation can be mitigated. Electrospinning technique is selected for production of sinuous targets inexpensively and with flexibility of imparting various physical properties. Although lot of work has been done in electrospinning of polymeric nanofibers not many works are done in ceramic/metallic nanofiber production especially in improving their thermal and mechanical properties. A low-cost lab-scale electrospinning unit is set up in-house and successfully produce different metallic, ceramic and composite nanofibers mats. Efforts are currently carried out to evaluate mechanical and thermal properties of single nanofiber using SEM-FIB and AFM. Some of these produced nanofiber mat will be exposed to high energy beam early next year to see their performance in practical situ ation. It is also proposed to design the nanofiber as mixture of different materials such as CNT dispersed in ceramics materials to improve the protection again radiation damage, better thermal properties, high heat dissipation, high mechanical strength.
