Abstract

On the GAMMA 10/PDX tandem mirror machine, divertor simulation experiments are carried out in the west end region by utilizing the particle flux from the confinement region. In order to control the particle flux and the ion temperature on the west end region, we have tried ICRF heating experiments with two types of antennas, double half turn (DHT) and Nagoya Type-III antennas, located in the west barrier cell. The ICRF heating in the barrier cell is effective for increasing the ion temperature at the end region. On the other hand, the particle flux is decreased due to the trapping of the ions from the central cell. This effect is more explicit by use of the Type-III antenna than the DHT antenna. The direct heating of the end-loss ions in the end region has been demonstrated to be effective for the increase of both ion temperature and particle flux.
