In a tokamak design what accelerates the plasma? Is it the current from the primary coils driving the plasma round?
God Plays Dice said:What about the current in the plasma? Doesn't current require motion of charge

A tokamak is a device used to achieve controlled nuclear fusion reactions. It consists of a toroidal (doughnut-shaped) vacuum chamber surrounded by powerful magnets, which confine and heat plasma (a hot, ionized gas) to the temperatures and pressures necessary for fusion to occur.
A tokamak accelerates particles through a process called "magnetic reconnection." This occurs when magnetic field lines in the plasma break and reconnect, releasing energy that accelerates particles in the process. This acceleration is also aided by the strong magnetic fields produced by the tokamak's magnets.
A tokamak primarily accelerates ions (positively charged particles) due to their greater mass and higher temperatures required for fusion. However, electrons can also be accelerated in the process, as they are needed to balance the charges of the ionized plasma.
Tokamak particle acceleration has the potential to unlock a virtually limitless source of clean energy through controlled nuclear fusion reactions. This could help reduce our dependence on fossil fuels and mitigate the effects of climate change. Additionally, tokamaks can also be used to study the fundamental properties of plasma and high-energy particles.
One of the biggest challenges of tokamak particle acceleration is achieving and maintaining the high temperatures and pressures needed for fusion to occur. This requires advanced technology and precise control of the plasma and magnetic fields. Additionally, the high-energy particles produced during the fusion process can damage the tokamak's components, requiring frequent maintenance and repairs.
