摘要: Abstract In addition to a reduced number of feeders, which would simplify their integration in the cryostat tokamak, present study considers possibility reduce voltage during safety discharge toroidal field (TF) coils. A lowered ease manufacture TF coils and operational risks. Both aspects closely related time constant, determined by ratio LTF/Rd, where Rd is resistance dump resistor LTF inductance coil. The supply current two or more series requires per fixed total 14.9 MA-turn provided DEMO baseline 2018. can be increasing conductor current, hence lowering inductance, an enlarged constant. For increased copper cross-section winding pack needs limit hot spot temperature acceptable values. parametric impact currents constants on radial build has been performed. advantages possible reduction need compared with disadvantages build.
