Electrically insulating materials for centrifugal mirrors
Nick R. Schwartz, Carlos A. Romero-Talamás, Marlene I. Patino +10
The centrifugal mirror confinement scheme incorporates supersonic rotation into a magnetic mirror device, which stabilizes and heats the plasma. This concept is under investigation…
