Plasma and Fusion Research   14(3) 2402055   Mar 2019   [Refereed]
<p>To investigate end-loss plasma control, several heating operations were carried out using ion-cyclotron range of frequency (ICRF) heating systems in GAMMA 10/PDX. In anchor region, one of the important heating positions to control the end loss ...

Plasma and Fusion Research   14(2) 2402033   Feb 2019   [Refereed]
<p>Effective ICRF heating creates a high ion-temperature plasma with strong ion-temperature anisotropy in the GAMMA 10/PDX central cell, where several Alfvén-ion-cyclotron (AIC) waves are spontaneously excited. It is clearly measured with a microw...

Plasma and Fusion Research   14(2) 2402032   Feb 2019   [Refereed]
<p>In the GAMMA 10/PDX tandem mirror, studies on divertor physics have been performed in the west end region by utilizing end-loss plasmas flowing from the confinement region. Since the plasma density in the end region is quite low (∼1016 </s...

Plasma and Fusion Research   14(2) 2401028   Feb 2019   [Refereed]
<p>We used the additional Ion Cyclotron Range of Frequency (ICRF) heating in the anchor cell for the high density plasma production. When the ICRF waves are excited with antennas installed in the anchor cell, it is observed that the plasma potenti...
