Current status of open magnetic systems for plasma confinement
Plenary
In this paper an overview of the recent progress and the near future plan of GAMMA 10/PDX project is described. The GAMMA 10/PDX tandem mirror has open magnetic field configuration and improvement of plasma confinement has been demonstrated by using potential formation [1].
By making best use of the open magnetic field, divertor simulation experiments have been started at the end-cell. One...

Worldwide activity of studies of plasma confinement in magnetic mirror traps decreased dramatically in the late 80's of the last century. The reason is that the mirror concept is thought to have three unattractive characteristics. The magnets are complex, the plasma is plagued with micro-instabilities and the electron temperature would never approach required keV levels. Researches on the Gas...

PLAMIS-\textrm{II} (PLAsma Material Interaction System) has been upgraded for plasma interaction experiments with various targets, such as Sn, Li, molten salts and ceramics.
Plasma beam of 30kW source is bended 90 degrees to a horizontal target by magnetic field. Target materials are placed on a rotating hearth, which is similar with circular tray and can be heated to 800$^\circ$C. We have...

KMAX, KeDa Mirror with Axisysmmetricity, is undergoing a major upgrade by adding colliding Field Reserved Configurations (FRCs) in the hope to improve the plasma content in the central cell region. Very much like many current FRC experiments, KMAX-FRCs will be formed on both ends by high voltage pulsed power and simultaneously injected into the central cell for colliding and merging. However,...

Overview of the activity on the development of the new multiple-mirror trap GOL-NB to be built in Budker Institute will be presented. This device will be created in BINP in several years as a deep conversion of the existing GOL-3 facility. The device will consist of a central trap with two 0.75 MW neutral beams, two multiple-mirror solenoids, two expander tanks and a plasma gun that creates...

Without current drive (CD) Field-Reversed-Configuration (FRC) disappears at skin time. Experiments in C-2U in Tri Alpha Energy strongly indicate that FRC survives much longer than skin time and thus suggest that some form of CD exists. In this presentation we are considering conditions under which FRC configuration can be maintained or even expanded. FRC as well as high-β open traps have a...
