| Abstract Scope |
Candidate advanced materials for fusion applications will face the combined extremes of neutron irradiation and plasma exposure, necessitating expanded experimental capabilities for probing simultaneous radiation damage and plasma exposure. Ion irradiation and helium implantation are well-established techniques used to study material responses in tungsten including defect propagation and “grass” structure formation. To enable large-scale studies for fusion applications, a 100 kV helium ion gun has been installed at the University of Wisconsin-Madison Ion Beam Laboratory, coincident with a 1.7 MeV Tandem Accelerator and high throughput irradiation stage. Building dual beam capabilities into the UW-IBL’s established high throughput approach has accelerated material testing by combining heavy ion irradiation and helium implantation with a platform which can accommodate 20 samples with no downtime between exposures. Campaigns of helium implantation and dual beam irradiation on tungsten have been conducted to benchmark this approach against existing literature before moving on to novel tungsten-based alloys. |
