SNS Sample Environment - Science & Technology
Developing New Sample Environment Capabilities at the SNS
SNS is ramping up its sample environment program. Capabilities are growing through a combination of standard equipment purchases, collaborative Research & Development, and the addition of new team members.
FERNS —
Fast Exchange Refrigerator for Neutron Science
— Enable high throughput cryogenic experiments
- Sample encapsulation
- Remote sample changes
- Fast thermal response
