Conceptual Design Review of DTT Diagnostic Equipment completed

The conceptual design of the DTT diagnostics was completed in March 2024. This comes at a very important time since in parallel the first version of the DTT Research Plan has been recently released (link). A DTT Diagnostics Design Review Committee (DTT-DIA-DRC) composed of G. Giruzzi(chair, CEA-France), R. Neu (IPP/Garching), O. Tudisco (DTT-Consortium), M. Valisa (RFX-Consortium), was appointed to review the consistency, completeness, and maturity of the design; assess the congruity of the costs and the adequacy of construction schedule; suggest possible simplifications and/or reduction of scope to reduce costs; evaluate the priority with respect to phase 1 and phase 2. A meeting was held in Frascati in June 2024 to review all the diagnostic systems. At the end of the meeting the committee members expressed their appreciation for the high level of competence of the diagnostics development teams, for the very good quality of their reports, the serious consideration that was given to the committee's comments and questions as well as the excellent level of the discussions held during the C-DRM. A final report has been released by the Committee on July 11. The final report sets priorities regarding the implementation of diagnostics with respect to Phase 1 and Phase 2 of DTT operation program. Although priority is given to the diagnostics considered indispensable for protection and plasma control in the first phase of DTT exploitation, the connection with the DTT Research Plan is a necessary criterion in setting priorities. The diagnostic systems progressively available during Phase 1 will be consistent with the programmatic objectives of supporting the preparation of the first part of the ITER exploitation.
