Abstract

Lower limits for time-resolved B ̄-parallel impurity fluxes to solid collectors immersed in the PLT edge plasma have been determined as a function of minor radius. Using geometric shadowing of the probe surface, features attributed to finite ion gyroradii are found. Also, for r < 48 cm, heat pulses of <2 ms duration and >2.5 × 10³ W/cm² intensity were found t occur at the termination of many discharges.
