The field lines travel around the axis of the tokamak. This magnetic field, however, is not sufficient by itself to contain the plasma. The magnetic field produced by the plasma current itself and other smaller stabilizing magnetic fields are all needed for confining the plasma. Tritium A radioactive isotope of hydrogen with one proton and two neutrons in its nucleus and one orbiting electron. For example, DOS stands for D isk O perating S ystem.
Radar stands for ra dio d etecting a nd r anging.
Another unit of energy measurement is the Joule. One calorie is equivalent to 4.1868 Joules. An ion that has lost electrons will have a positive charge. A plasma is composed of ions and free electrons. Isotope A form of an atomic element that has a different mass from the normal element, because of a different number of neutrons in the atomic nucleus.
