FYI: mame 45 TESLA high-field na REBCO.... narozdil od ITERU 5 Tesla supravodic z 50.tych let s Niobem
pres 20 TESLA to ma jiz pres 30 let
REBCO (REBa2Cu3Ox, where RE = Y, Gd)
nedostatek chemickych fyziku imo, materialovych chemiku a fyziku se znalosti chemie.... tolik k materialum
45.5-tesla direct-current magnetic field generated with a high-temperature superconducting magnet https://www.nature.com/articles/s41586-019-1293-1
+ je to odolne proti Quenchi
ja to netusil, vsiml jsem si toho dnes nahodou pri cteni supravodicu pri pokojove teplote, high-pressure
ale je jiste ze to vedouci zodpovedni za ITER totalne podelali
podivej se na ty kalkulace
This can be seen by noting that 9.2 T ARC has a fifth of the ∼$24B price of the 5.3 T ITER (calculated by applying the fabricated component scaling to the ∼ 23,000 tonne ITER). Yet ARC matches ITER's fusion power and produces net electricity. The cost of ARC is approximately one-third the cost of the 8 T ARIES-RS (∼$14B), but ARIES-RS has approximately four times the electrical output. The smaller ARC is appropriate for an “entry-level” fusion Pilot plant, but there likely exists a better economic optimization of magnetic field strength versus mass for a full power plant.
REBCO v ARC vs ITER (niobium-tin (Nb3Sn), "REBCO-free ITER fail")
A natural comparison is ITER which also produces 500 MW of fusion power with a similar shaping (ϵ ∼ 0.33), but with B0 ∼ 5.3 T. As expected from the dependence in fusion power density, the peak on-coil field of Bcoil,max ∼ 20 T enabled by REBCO technology allows ARC to achieve a FNSF/Pilot-relevant areal fusion power density (∼3 MW/m2) in a device with roughly a tenth of ITER's volume. Additionally, as a consequence of the high toroidal field, the ARC design point has double the safety factor of ITER, making it more robust against disruptions.
