TL;DR: The C-2W experimental device (also called "Norman") as discussed by the authors is the world's largest compact-toroid (CT) device, which has several key upgrades from the preceding C2U device such as higher input power and longer pulse duration of the NBI system as well as installation of inner divertors with upgraded electrode biasing systems.

Enhanced magnetic field probe array for improved excluded flux calculations on the C-2U advanced beam-driven field-reversed configuration plasma experiment
TL;DR: A new array of B-dot probes and Rogowski coils were installed to better determine the amount of flux leaked out of the system and ultimately provide a more robust measurement of plasma parameters related to pressure balance including the excluded flux radius.

Absolute calibration of neutron detectors on the C-2U advanced beam-driven FRC
R. M. Magee,R. Clary,Sergey Korepanov,F. Jauregui,I. Allfrey,E. Garate,T. Valentine,Artem Smirnov +7 more
TL;DR: The absolute, in situ calibration of scintillation neutron detectors via two independent methods: firing deuterium beams into a high density gas target and calibration with a 2 × 107 n/s AmBe source are described.
