Abstract Text:
Several new experiments have been conducted on the UC Davis repetitive-pulsed spheromak-like compact toroid (SCT) accelerator (CTIX). (1) SCT density and kinetic energy density has been increased by gas puffing in the acceleration section. With gas puffing, SCT electrical to kinetic energy conversion efficiency has been increased to > 20%. (2) SCT interaction with targets has been recorded with a fast visible imaging system, combined with target-region He gas puffing for increased brightness. Both coherent and chaotic wave images were observed in the target region after the interaction. (3) A laser deflection density diagnostic has been improved to obtain better reliability and resolution. Operated with high-density gas-puffed SCTs, the second-generation diagnostic has successfully measured axial as well as radial deflection. The measured line averaged densities are in good agreement with a conventional quadrature laser interferometer.
