Staff in ORNL is super nice and willing to assist you to fulfill your project. Tools there is cool for researchers. I feel happy to be an user during my Ph. D. every time I went there and become very productive, which means that I obtained 50 more devices than the number of devices I usually work at my university.
The scene at the ridges are nice and sometimes you can jog or run along the lake, especially when you have a long day for device fabrication.
