Plasma flow patterns in a super-X-divertor-like configuration are investigated by using a one-dimensional plasma fluid model with the anisotropic-ion pressure (AIP model). The AIP model enables to treat supersonic plasma flows self-consistently by de

Gas puff and pump experiments on the plasma applied in a divertor simulation were conducted in the GAMMA 10/PDX tandem mirror. Additional hydrogen gas was supplied to the plasma with and without a pump in the region of the divertor simulation. To dec

In the GAMMA 10/PDX tandem mirror, plasma with strong ion-temperature anisotropy is produced by using the ion cyclotron range of frequency waves. This anisotropy of ion temperature causes several Alfven-Ion-Cyclotron (AIC) waves to spontaneously exci
