Experiments are planned to produce a high-β hot-electron ring in the anchor and plug regions of the Hanbit tandem mirror. Initially, an existing 14-GHz 2-kW klystron will be used to provide microwave power at the fundamental and 2nd harmonic for electron cyclotron heating (ECH) in an over-moded cavity. Experiments will test the concept in the maximum-B plug region and/or the minimum-B anchor region. Plans also include adding additional power to increase the electromagnetic field strength in the region of the resonances. The ultimate goals are to make a hollow high-beta plasma in the maximum-B plug region as has been done in many devices and to make a hollow high-beta plasma in the minimum-B anchor region as was done in the Constance-B device. This experiment should allow a test the concept of high-m ballooning stability provided by an electron ring in a tandem mirror. The addition of a cavity in the central cell will also allow production of an ECH plasma to increase the electron temperature and to ease the plasma production and matching requirements of the ICRF antennas. Calculations are underway to determine the power requirements and expected plasma parameters in these regions.
