When electron cyclotron resonance (ECR) appears inside the Tokamak chamber for given pumping frequency (f = 1.25 GHz) a plasma with density greater than 2 x 10 to the 18th power/cu m and temperature T sub e = 10 to 40 eV is produced. Plasma is sustained at some lower value of the density during the whole RF pulse. Simultaneously, a toroidal current up to approximately or equal to 0.2 kA is generated. The energy confinement time is estimated to be about 30 microsec during the ECR breakdown. 收起
