Japan Atomic Energy Agency (hereinafter referred to as "JAEA") asked the assessment committee, "Evaluation Committee of Research and Development Activities for Fusion" (hereinafter referred to as "Committee") for in-advance evaluation of "Research and Development of the technical system for extraction of fusion energy," in accordance with "General Guideline for the Evaluation of Government R&D Activities" by Cabinet Office, Government of Japan, "Guideline for Evaluation of R&D in Ministry of Education, Culture, Sports, Science and Technology" and "Regulation on Conduct for Evaluation of R&D Activities" by JAEA. In response to the JAEA's request, the Committee assessed the research program of the Fusion Research and Development Directorate (hereinafter referred to as "FRDD") during the period from April 2015 to March 2022. The Committee evaluated the management and research activities of the FRDD based on the explanatory documents prepared by the FRDD, the oral presentations with questions-and-answers by the Director General and the Deputy Director Generals.

Japan Atomic Energy Agency is developing control and data acquisition systems for poloidai polarimeter, edge Thomson scattering system, divertor impurity monitor, IR thermography and micro fission chamber in ITER project. We developed supervisory control system, which coordinates internal devices such as detectors and laser system following discharge sequence, leading other domestic agencies. Supervisory system configures measurement parameters and performs consistency check between the parameters. We also developed sequence control function to coordinate control programs for measurement and auxiliary devices complying to ITER standards and guidelines. A flowchart conversion tool was developed. The conversion tool reduced troubles in the program codes. It also makes changes of control logic flexible. We also developed prototype data acquisition system communicating with a central control simulator. The prototype demonstrates that our system design was valid.

In order to validate the millimeter wave design procedure, the EL mock-up has been constructed and the low power test has been carried out by using mW-level low power RF oscillators. The test has been carried out with critical four edged beams instead of all eight beams in the upper waveguide unit. The measured data has been compared with design at several important locations in the launcher and after the launcher exit with steering mirror angle changed. The comparison of the measured beams propagation and the design shows good agreement for the beam sizes and the beam orientation performance. The quantitative evaluations has been carried out and the design procedure's reasonability has been confirmed.
