Achievement of Record beta in the START Spherical Tokamak

Achievement of Record beta in the START Spherical Tokamak

Achievement of Record beta in the START Spherical Tokamak 150 150 UKAEA Opendata

Values of beta T > 30% have been achieved and sustained for several confinement times on the START spherical tokamak using additional heating provided by neutral beam injection. These values are more than twice the highest value previously obtained in a tokamak, and correspond to normalized beta values of betaN > 4.
