Description: During FY 82, much effort was devoted to work in support of alternate confinement concepts, especially those involving field reversal. This work includes: (1) development of particle and energy confinement scaling for the Reversed Field Pinch (RFP) and the Field Reversed Theta Pinch (FRTP), and (2) analysis of start-up (heating and plasma build) for the spheromak and Field Reversed Mirror (FRM). In addition, a block of projects were concerned with fusion product effects, including heating and ash build-up. These include, (1) a study of possible use of radial electric fields to control ash build-up in tokamaks, (2) effects of alpha-driven microinstabilities on heating in tokamaks, and (3) fusion product transport, including effects of large angle scattering on orbits, in EBT and FRM devices. In a related study, the possibility of hot-ion mode operation (assuming strong transfer of fusion product energy to ions, e.g. via microinstabilities) was done with emphasis on calculation of ion-electron equilibration rates.
