A series of stationary two-dimensional
(both parallel and transverse to the magnetic field) weak
double layers with three, four, or more potential steps
has been observed in a laboratory experiment in magnetized plasma
in Ref. [1].
In this work, we present the results of kinetic and experimental study
of the effect of magnetic
field configuration on the nonthermal plasma...

The divertor simulation research has been started by making use of high heat-flux plasma flow from the large tandem mirror device GAMMA 10/PDX in Plasma Research Center [1-2]. A crucial advantage of using large tandem mirror is a capability of generating ion flux with high temperature (100$\sim$ 400 eV) comparable to SOL plasma parameters and its controllability.$\\$
In GAMMA 10/PDX,...

In GAMMA 10/PDX, studies on the boundary plasma and plasma surface interaction have been done using the end region making best use of the tandem mirror device. The features of GAMMA 10/PDX for the boundary plasma and PSI studies are the following: (1) high ion temperature of the plasma exposed to the D-module (i.e. a few hundreds eV), (2) high magnetic field (0.15 $\sim$ 1.5 T), (3) large...

Ion sensitive probe (ISP) is an electrical probe used for measuring ion temperature (Ti) in magnetized plasmas [1]. Simultaneously, electron temperature (Te) and plasma space potential (Vs) are also available. Recently, the ISP was installed in the divertor simulation module (D-module) of the largest tandem mirror plasma device GAMMA 10/PDX in order to evaluate the property of the high...

Tungsten is foreseen presently as the main candidate armour material for the divertor targets in ITER. During tokamak transient processes, such as Edge Localized Modes (ELMs) and mitigated disruptions, the armour material is exposed to intense streams of hot plasma that can cause a severe erosion of the exposed material. Erosion restricts lifetime of the divertor components and leads to...

The residual mechanical deformation and stress were measured in the preliminary experiments carried out at synchrotron radiation (SR) scattering stations on VEPP-3 in the Siberian Center of Synchrotron and Terahertz Radiation. The deformation and stress were calculated on the base of the dependence of the scattering angle on the inclination of the tungsten sample. Significant changes in the SR...

The fuel retention and the lifetime of plasma-facing components are critical plasma-material interaction factors potentially limiting the availability of a magnetic fusion reactor. Linear plasma devices are excellent test beds for investigating specific questions of plasma-material interaction. The materials can be tested under well-defined exposure conditions relevant to both divertor and...
