Abstract JET returned to deuterium-tritium operations in 2023 (DTE3 campaign), approximately two years after DTE2. DTE3 was designed as an extension of JET's 2022-2023 deuterium campaigns, which focused on developing scenarios for ITER and DEMO, integrating in-depth physics understanding control schemes. These were evaluated with mixed D-T fuel, using the only remaining tritium-capable tokamak until its closure 2023. A core-edge-SOL integrated H-mode scenario developed tested D-T, showing...
Recent global events have distinctly demonstrated the need for fast diagnostic analysis of targets in a liquid sample. However, microfluidic lab-on-a-chip devices point-of-care diagnostics can suffer from slow due to poor mixing. Here, we experimentally explore mixing effect within chamber, as obtained superparamagnetic beads exposed an out-of-plane (vertical) rotating magnetic field. Various protocols are explored, and level sample homogeneity is measured by determining efficiency index. In...
Abstract The DIII-D tokamak has elucidated crucial physics and developed projectable solutions for ITER fusion power plants in the key areas of core performance, boundary heat particle transport, integrated scenario operation, with closing core-edge integration knowledge gap being overarching mission. New experimental validation high-fidelity, multi-channel, non-linear gyrokinetic turbulent transport models provides strong confidence it will achieve Q ⩾ 10 operation. Experiments identify...
Abstract Control of heat exhaust is essential for the operation power producing fusion reactors. Here, we present results feedback control experiments in JET and AUG. In JET, demonstrate first X-point radiator (XPR) DD DT discharges using argon seeding. AUG, improve XPR with nitrogen seeding, resulting achieving detached L-H H-L transition (in a single discharge). The controllers are designed model-based design procedure. required models obtained experimentally perturbative (system...
