Description
Summary:Summary form only given, as follows. Additional microwave power has been installed at Hanbit in an attempt to increase the beta of the hot-electron ring plasma created in the plug section. Two VA-806 series klystrons with a frequency of /spl sim/8 kW have been installed to operate in conjunction with an existing 2-kW 14-GHz klystron already, used in previous experiments. A hot-electron ring is created in the plug in order to provide a high-beta ring to stabilize the Hanbit central cell plasma against ballooning instabilities. Previous experiments had shown that a hot-electron ring plasma had been created with the 14-GHz klystron. The hot-electron ring was in a favorable location to stabilize the CC plasmas but the plasma beta was too low and could not provide stability. The present experiments were designed to increase the beta with additional microwave power. In addition, diagnostics were installed to determine the length of the plasma New diagnostic techniques and measurements will be presented.
