Diagnostic alkali atom (e.g., lithium) beams are routinely used to diagnose magnetically confined plasmas, namely, to measure the plasma electron density profile in the edge and the scrape off layer region.

Article Synopsis
  • A new video camera called EDICAM has been developed for the Wendelstein 7-X stellarator to meet specific monitoring needs and challenges.
  • The camera features a 1.3 Mpixel CMOS sensor that allows for quick analysis of small areas, even during lengthy exposure times, and can run simple data evaluation algorithms.
  • In initial tests, multiple EDICAMs successfully captured long exposure images of plasma while also monitoring rapid edge plasma turbulence, revealing significant insights into turbulence structures across the stellarator's modules and suggesting updates for future fusion experiments like ITER.

Wendelstein 7-X, a superconducting optimized stellarator built in Greifswald/Germany, started its first plasmas with the last closed flux surface (LCFS) defined by 5 uncooled graphite limiters in December 2015. At the end of the 10 weeks long experimental campaign (OP1.1) more than 20 independent diagnostic systems were in operation, allowing detailed studies of many interesting plasma phenomena.

Light reflections are one of the main and often underestimated issues of plasma emissivity reconstruction in visible light spectral range. Metallic and other specular components of tokamak generate systematic errors in the optical measurements that could lead to wrong interpretation of data. Our analysis is performed at data from the tokamak COMPASS.
