Model C stellarator
The Model C stellarator was an important stellarator operating at the Princeton Plasma Physics Laboratory from 1961-69.[1]
Design parameters
The Model C had a racetrack shape. The total length (of the tube axis?) was 1.2m. The plasma could have a 5-7.5 cm minor radius. Magnetic coils could produce a toroidal field (along the tube) of 35,000 Gauss.[1] It was only capable of pulsed operation.
It had a divertor in one of the straight sections. In the other it could inject 4 MW of 25 MHz ion cyclotron resonance heating (ICRH).
It had helical windings on the curved sections.
Results
An average ion temperature of 400 eV was reached in 1969.
History
Construction funding/approval was announced in April 1957.[2]
Starts operating March 1962.[3]
The Model C was reconfigured as a tokamak in 1969,[1] becoming the Symmetric Tokamak (ST).[4]
