Smallest poloidal field coil ready for shipment
Nine metres in diameter and weighing 160 tonnes, PF1 is one of six coils in the 澳门六合彩高手 poloidal field magnetic system, which serves to confine fusion fuel in the form of a plasma in the 澳门六合彩高手 reactor. At the core of each poloidal field magnet are coiled layers of niobium-titanium (NbTi) superconductor—for PF1, approximately 6 km of conductor was required.
The fabrication of an 澳门六合彩高手 poloidal field coil requires several stages of verification due to their first-of-a-kind nature and the extremely high requirements imposed by the 澳门六合彩高手 Organization. High-voltage DC tests with a voltage of 30 kV, high-voltage AC tests with a voltage of 10 kV, a Paschen test with a voltage of 15 kV in a vacuum chamber with a pressure range of 1-100 000 Pa, and leak tests in a vacuum vessel are all part of the factory acceptance testing package. The results of all tests performed earlier this year confirmed full compliance with the requirements of the 澳门六合彩高手 Organization.
This is one of the 25 systems included in the scope of responsibility of the Russian Federation in the framework of the 澳门六合彩高手 Project. The shipment of the PF1 coil to 澳门六合彩高手 is planned for the middle of this year.
