Page 3 - Study of Neutral Gas Pressure Dynamics in C-2W Using Inverted Magnetron Ionization Gauges
P. 3
Universal imaging challenge posed by linear systems is addressed by the C-2W imaging suite
A suite of 7 high-speed spectrally-filtered imaging cameras has been deployed to comprehensively visualize the plasma throughout the device.
Inner divertors:
high vacuum pumping
Neutral beams: ~21 MW, ~30 ms
Formation sections:
~15 mWb trapped flux
Outer divertors:
high vacuum pumping
Plasma guns and biasing electrodes: high voltage & long pulse capability
Confinement vessel:
skin time <3 ms
Magnet system:
field ramp & active control

All instruments are directly mounted to the machine.
Maintains high optical throughput necessary for high- speed imaging.
Keeps overall system cost manageable.
All instruments are subject to harsh EMI and DC magnetic field, capable of reliable measurements up to 1.6 kG
