In June 2014, EMC2 demonstrated for the first time that the electron cloud becomes diamagnetic in the center of a magnetic cusp configuration when beta is high, resolving an earlier conjecture.
In June 2014, EMC2 demonstrated for the first time that a high beta configuration dramatically improves plasma confinement in a magnetic cusp system. They showed that the electron cloud becomes diamagnetic in the center of the device when β is high, resolving an earlier conjecture.
