MiHoYo successfully tested 70 tokamak 'electron guns' and invested in nuclear fusion technology to achieve energy singularity.

News from this site on December 18, the "Energy Singularity FusionEnergy" public account announced that the local spiral magnetic flux injection system of the Honghuang 70 high-temperature superconducting tokamak device was successfully tested recently.

Local Helicity Injection system (Local Helicity Injection) is an electric vacuum radiation source device, commonly known as "electron gun", its working principle is to break down the gas to generate electrons through high voltage between the cathode and anode, and extract the electron beam and inject it into the tokamak device.

According to reports, in the Honghuang 70 device, the main function of the electron gun is to pre-ionize the gas and assist in gas breakdown. At the same time, it can also inject spiral magnetic flux into the plasma through the electron beam to stimulate higher The plasma current achieves the purpose of current driving. Compared with the traditional thermal emission electron gun, the Honghuang 70 electron gun adopts a cold cathode design and has a more compact structure, which is conducive to concentrating electrons to increase the extraction current and avoids the impurity problem caused by the heating wire. This electron gun was designed and developed by Energy Singularity. It adopts an innovative structural design and is only equivalent to the size of a shoe box.

, has been authorized by the invention patent. According to previous reports on this site, Honghuang 70 was designed, developed and constructed by Energy Singularity, and the overall installation was undertaken by China Nuclear Industry Fifth Construction Co., Ltd.

. The entire magnet system of the Honghuang 70 device, including toroidal field (TF) coils, poloidal field (PF) coils and central solenoid (CS) coils, are constructed of high-temperature superconducting materials. By then, Honghuang 70 will become the world's first fully high-temperature superconducting tokamak device that is completed and operational, and will be the first to verify the engineering feasibility of the high-temperature superconducting tokamak technology route at the complete device level. Public information shows that Energy Singularity Energy Technology (Shanghai) Co., Ltd. was established in June 2021. The legal representative is Yang Zhao, who graduated from the Department of Physics of Peking University in 2009 and received a PhD from the Department of Physics at Stanford in 2013-17. Research directions include the intersection of quantum gravity and quantum information, as well as the intersection of artificial intelligence and tensor networks.
