Laser-induced breakdown spectroscopy (LIBS) has been widely studied due to its unique
advantages such as remote sensing, real-time multi-elemental detection and none-to-little …

Laser-induced breakdown spectroscopy (LIBS) has emerged as a powerful analytical
method for the elemental mapping and depth profiling of many materials. This review offers …

The elemental analysis of plasma-facing components (PFCs) with deposits is vital for the
study of the material erosion, deposition, and fuel retention. For ITER-like divertor, first wall is …

W7-X completed its plasma operation in hydrogen with island divertor and inertially cooled
test divertor unit (TDU) made of graphite. A substantial set of plasma-facing components …

A set of dedicated marker samples consisting of fine-grain graphite as substrate, an
interlayer of 0.2–0.4 μm molybdenum (Mo) employed as marker, and a 5–10 μm thick …

The objective of the present study has been to evaluate the potential applications of
picosecond laser-induced breakdown spectroscopy (ps-LIBS) in nuclear fusion devices. The …

Carbon net erosion and deposition at the test divertor unit (TDU) of Wendelstein 7-X (W7-X)
were measured for the discharge period OP 1.2 b in the year 2018 using 18 specially …

Distributions of deposits and hydrogen (H) on the graphite divertor target elements TM4h4
and TM3v5 in the test divertor units 3 (TDUs3) of Wendelstein 7-X (W7-X) are studied. The …

In order to get first insight into net tungsten erosion in W7-X, tungsten (W) marker layers
were exposed during the operational phase OP 1.2 b at one position of the Test Divertor Unit …

The net carbon erosion rate at the divertor strike line of W7-X was determined
experimentally during the operational phases OP 1.2 a and OP 1.2 b [M. Mayer et al. Phys …
