Control of radial particle and thermal transport is instrumental for achieving and sustaining well-confined high-β plasma in a Field-Reversed Configuration (FRC). Radial profiles of low frequency ion gyro-scale density fluctuations (0.5 ≤ kρs ≤ 40), consistent with drift- or drift-interchange modes, have been measured in the scrape-off layer (SOL) and core of the C-2 Field-Reversed Configuration (FRC), together with the toroidal ExB velocity.

An end loss analyzer system was developed to study thermal transport on the open field lines that surround the advanced beam-driven field-reversed configuration (FRC) core of the C-2U experiment. The system is mounted directly to the divertor electrode and consists of gridded retarding-potential analyzers that measure ion current density and ion energy as well as pyroelectric crystal bolometers that measure the total power flux.
