Solid--end-plug experiment on a theta pinch

Results from the first end-stopping experiment on a high-energy (T/sub i/ approx. 1.5 keV, n approx. 10/sup 16/ cm/sup -3/) theta pinch are reported. The experiment was done with quartz end plugs. The results show that the insertion of the plugs improves plasma stability, reduces particle end loss out of the device, and improves the energy confinement.
