Appearance and analysis of a reflecting coating damage [PDF]

EPJ Web of Conferences
Eight reflecting gratings are installed into the plasma facing wall of ASDEX Upgrade (AUG) in order to provide a controlled second pass through the plasma centre in 140 GHz heating scenarios with reduced single pass absorption. Four of these gratings are

Intense intermittent radiation at the plasma frequency on EAST [PDF]

EPJ Web of Conferences, 2019
Intense intermittent radiation has been observed regularly in EAST by using a Michelson interfer-ometer and a Q-band radiometer system. The radiation bursts are related to a fast process with characterization time of a few microseconds.

Confirmation of the topology of the Wendelstein 7-X magnetic field to better than 1:100,000

Nature Communications, 2016
Early stellarator designs suffered from high particle losses, an issue that can be addressed by optimization of the coils. Here the authors measure the magnetic field lines in the Wendelstein 7-X stellarator, confirming that the complicated design of the

Further upgrades of the ASDEX Upgrade ICRF system [PDF]

EPJ Web of Conferences
The original plans were to operate the tokamak ASDEX Upgrade (AUG) for ten years. The flexibility of the experiment lead to the fact, that AUG is now operating for over three decades.

A megawatt-level 28 GHz heating system for the National Spherical Torus Experiment Upgrade

EPJ Web of Conferences, 2015
The National Spherical Torus Experiment Upgrade (NSTX-U) will operate at axial toroidal fields of ≤ 1 T and plasma currents, Ip ≤ 2 MA. The development of non-inductive (NI) plasmas is a major long-term research goal for NSTX-U.
