Abstract

Using the method of transient CHI, world-record non-inductive start-up plasma current flowing on closed field lines in a toroidal confinement device of 160 kA has been unambiguously achieved. The resulting plasmas have electron temperatures of about 20 eV and decay resistively in several ms. Planned future experiments will include studying the effect of Li conditioning to reduce low Z impurities and its impact on the ability to demonstrate flux savings with CHI start-up.
