There are several answers to this question. Since all equations describing the motion of charged particles in fields are known, including the effects of collisions, detailed numerical (gyrokinetic) simulations are possible. | There are several answers to this question.

However, due to the enormous disparity between the minimum and maximum scales involved (gyration times vs. transport times, and the gyroradius vs. the machine size), this is a major challenge. | However, due to the enormous disparity between the minimum and maximum scales involved (gyration times vs. transport times, and the gyroradius vs. the machine size), this is a major challenge. | ||
