Absolute calibration of neutron detectors on the C-2U advanced beam-driven FRC

August 2016 | R. M. Magee | Review of Scientific Instruments | Paper

In the C-2U fusion energy experiment, high power neutral beam injection creates a large fast ion population that sustains a field-reversed configuration (FRC) plasma. The diagnosis of the fast ion pressure in these high-performance plasmas is therefore critical, and the measurement of the flux of neutrons from the deuterium-deuterium (D-D) fusion reaction is well suited to the task.

Fast imaging diagnostics on the C-2U advanced beam-driven field-reversed configuration device

August 2016 | E. M. Granstedt | Review of Scientific Instruments | Paper

The C-2U device employed neutral beam injection, end-biasing, and various particle fueling tech- niques to sustain a Field-Reversed Configuration (FRC) plasma. As part of the diagnostic suite, two fast imaging instruments with radial and nearly axial plasma views were developed using a common camera platform.
