CFETR (China Fusion Engineering Test Reactor) concept design work was started in 2012. It is developed in two stage. CFETR-Phase I is designed with major radius R=5.7m, minor radius a=1.6m and magnetic field at plasma region BT=4-5T. 16 toroidal field coils and 6 central solenoid coils were designed by Nb3Sn CICC with maximum operation current of 64 kA and 50 kA, respectively. Three types of...
The Central Solenoid Model Coil (CSMC) of China Fusion Engineering Testing Reactor (CFETR) is designed to operate max current is 47.65kA and get the highest magnetic field 12 T, the maximum magnetic field rate is designed 1.5 T/s. The CSMC consists of 5 independent coils, the Nb3Sn Inner and Outer coils, the Upper, Middle and Lower NbTi coils. The Nb3Sn conductor for the CSMC was manufactured...
The possibility to trigger the proton-boron nuclear fusion reaction (p + 11B → 8.5 MeV + 3a) by using a nsec class laser has been recently demonstrated. This is of high interest since such reaction does not produce any neutrons but just three alpha-particles, which could be used for applications in different fields. The possibility to confine the plasma fuel generated during laser-target...
The interplay between a nuclear fusion plasma and the reactor wall determines the performance and lifetime of fusion reactors. DIFFER's main experiment Magnum-PSI is the only laboratory setup in the world capable of exposing materials to plasma conditions similar to those of future fusion reactors. The success of the Magnum-PSI experiment depends on the generation of a 2.5 T magnetic field...
The R&D method for the large Nb3Sn magnets of the EUROfusion DEMO device was proposed since 2013 by the Swiss Plasma Center. A first prototype conductor (RW1) was tested in the EDIPO test facility in 2015 up to 82 kA at 13 T, confirming the low thermal strain and the lack of cyclic load degradation. After the baseline of the DEMO device was updated in 2015, the new requirements led to an...
According to the European Roadmap to Fusion Electricity, DEMO in Europe is considered to be the nearest-term reactor design to follow ITER and capable of producing electricity and to be a facilitating machine between ITER and a commercial reactor; to achieve this goal the capital costs has to be minimized, including the construction cost of magnets and conductors. Despite the successful large...
