Fellow-Projekt: „Development of three-dimensional tomography of plasma radiation using imaging bolometers on the W7-X experimental device“

The research I intend to carry out during my sabbatical leave to the Max Planck Institute for Plasma Physics (IPP) in Greifswald with the support of the Krupp Foundation is a continuation of the collaborative research between IPP and my employer, the National Institute for Fusion Science (NIFS) in Toki, Japan that I have been carrying out with colleagues from IPP since 2017. The project involves the development of an Infrared Imaging Video Bolometer (IRVB) diagnostic device that was recently installed on the W7-X device at IPP. The primary objective of this project is

  1. to bring the IRVB on W7-X into operation and develop the data analysis tools to produce the radiation images from the raw IR camera data. The secondary objectives will be as follows:
  2. to use the bolometer diagnostics as well as other W7-X diagnostics to investigate various radiative phenomenon such as detached plasma, radiative collapse, radiative asymmetries, radiation from impurity seeding, etc.,
  3. to develop a weighted sum technique using both resistive bolometers and the IRVB to estimate the total radiated power,
  4. to evaluate potential future IRVB installation locations on W7-X and make preliminary designs with the aim of developing a 3D tomography system,
  5. to develop tomography tools for 2 and 3D tomography of radiated power using bolometer diagnostics on W7-X.
