Abstract :
The Princeton FRC (PFRC) is a compact device that utilizes odd-parity[1] radio-frequency rotating magnetic fields (RMFo) to heat electrons[2] and drive azimuthal current in a cylindrical plasma column. A serendipitous discovery is that the RF system serves as a useful diagnostic tool, providing data on RF-field penetration into the plasma.[3] Efficient use of RF power is required to accommodate the small size of the device and for its development into a practical fusion reactor. The RF system is described along with its evolution and lessons learned.
