C-2U is a macroscopically stable, high-performance field-reversed configuration (FRC), where high plasma temperatures with significant fast ion population and record lifetimes were achieved.

Knowledge and control of the axial outflow of plasma particles and energy along open field lines are of crucial importance to the stability and longevity of advanced beam-driven FRC plasma.

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.
