Non-inductive Start-up and Formation of Spherical Torus by Using Electron Cyclotron Range of Frequency on LATE.

Non-inductive start-up and formation of spherical torus by using electron cyclotron range of frequency have been studied in the LATE device with microwaves at 2.45 GHz and 5 GHz. A plasma current is initiated and ramped up to Ip≃8.1 kA with a 2.45 GHz microwave power of 35 kW, and Ip≃20 kA with a 5 GHz power of 190 kW, resulting in the formation of a spherical torus.
