End loss analyzer system for measurements of plasma flux at the C-2U divertor electrode

End loss analyzer system for measurements of plasma flux at the C-2U divertor electrode

March 2016 | M. E. Griswold | AIP Conference Proceedings | Paper

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.

Gyrokinetic particle simulation of a field reversed configuration

Gyrokinetic particle simulation of a field reversed configuration

January 2016 | D. Fulton | Physics of Plasmas | Paper

Gyrokinetic particle simulation of the field-reversed configuration (FRC) has been developed using the gyrokinetic toroidal code (GTC). The magnetohydrodynamic equilibrium is mapped from cylindrical coordinates to Boozer coordinates for the FRC core and scrape-off layer (SOL), respectively.
