description •Strategy and status of the development of new diagnostic systems for the COMPASS-U tokamak with high plasma densities, high heat flux densities and a hot vacuum vessel are provided.•Plans for the diagnostic set for the first plasma at COMPASS-U are reviewed.•Several new and worldwide unique diagnostic solutions like high-temperature compatible hall probes, fast thick printed copper coils and a sub-millimetre interferometer with an unambiguous channel are introduced. The COMPASS-U tokamak (R = 0.894 m, a = 0.27 m, Bt = 5 T, Ip = 2 MA) is a new medium-size device with fully metallic plasma facing components, currently under construction at the Institute of Plasma Physics of the Czech Academy of Sciences in Prague. It features a unique combination of parameters, such as a high temperature of the tokamak walls up to 500 °C allowing a high recycling regime, a high magnetic field connected with a high plasma density above 1020m−3 and with a high heat flux (perpendicular to divertor targets) density at the outer strike-point up to 90 MW/m2 in attached conditions. These parameters of the device pose strict constraints and requirements on the design of individual diagnostic systems. Strategy and present status of the development of the diagnostic systems for COMPASS-U are provided. Plans for a diagnostic set for the first plasma are reviewed. The review of the diagnostics systems involves the high-temperature compatible slow (up to 20 kHz) and fast (up to several MHz) inductive and non-inductive magnetic sensors (including Thick Printed Copper coils and Hall sensors), the sub-millimetre interferometer with an unambiguous channel, Electron Cyclotron Emission, the interlock and overview cameras, high resolution Thomson scattering, radiation diagnostics (neutron diagnostics, soft and hard X-ray diagnostics, bolometers, impurity monitors, effective ion charge), probe diagnostics (including rail probes) and manipulators.

These parameters of the device pose strict constraints and requirements on the design of individual diagnostic systems. Strategy and present status of the development of the diagnostic systems for COMPASS-U are provided. Plans for a diagnostic set for the first plasma are reviewed. The review of the diagnostics systems involves the high-temperature compatible slow (up to 20 kHz) and fast (up to several MHz) inductive and non-inductive magnetic sensors (including Thick Printed Copper coils and Hall sensors), the sub-millimetre interferometer with an unambiguous channel, Electron Cyclotron Emission, the interlock and overview cameras, high resolution Thomson scattering, radiation diagnostics (neutron diagnostics, soft and hard X-ray diagnostics, bolometers, impurity monitors, effective ion charge), probe diagnostics (including rail probes) and manipulators.</abstract><cop>Netherlands</cop><pub>Elsevier B.V</pub><doi>10.1016/j.fusengdes.2023.113545</doi><orcidid>https://orcid.org/0000-0001-8936-7578</orcidid><orcidid>https://orcid.org/0000000189367578</orcidid><oa>free_for_read</oa></addata></record>
