Plasma-wall interaction of advanced materials

Plasma Dynamics and Plasma Wall Interaction

High power and particle deposition on target materials are encountered in many applications including magnetic and inertial fusion devices, nuclear and high energy physics applications, and laser and discharge produced plasma devices. Surface and structural damage to plasma-facing components due to the frequent loss of plasma confinement remains a serious problem for the Tokamak reactor concept...

Laser-produced plasma-wall interaction

Jets of laser–generated plasma represent a flexible and well-defined model environment for investigation of plasma interactions with solid surfaces (walls). The pilot experiments carried out on the iodine laser system (5–200 J, 0.44 mm, 0.25–0.3 ns, ,1 10 W/cm) at the PALS Research Centre in Prague are reported. Modification of macroscopic characteristics of the Al plasma jets produced at laser...

Eects of plasma disruption events on ITER ®rst wall materials

In ITER, plasma disruption events may occur producing large fast thermal transients on plasma facing materials. Particularly important for the integrity of the ®rst wall (FW) are relatively ÔlongÕ duration o€-normal events such as plasma vertical displacement events (VDE) and runaway electrons (RE). An analytical methodology has been developed to speci®cally assess the e€ect of these events on ...
