Simple annulus power balance in EBT-I
Simple annulus power balance in EBT-I
A power balance for the electron rings which includes drag cooling in addition to the radiation (synchrotron and bremsstrahlung) and annulus electron--electron scattering losses, indicates that drag dominates the annulus energy balance in EBT-I. Drag cooling of the relativistic annulus electrons on the toroidal core plasma appears to provide a reasonable explanation for the decrease in the annulus electron temperature in going from ELMO to EBT-I. Theoretical estimates of the microwave power required to sustain the annulus are found to be within a factor of 2 of the experimentally determined value. Scaling projections are shown for EBT-S and parametric study results for ELMO, EBT-I, and EBT-S are presented for various microwave power levels. The Maxwellian distribution function is assumed in these calculations.
