The target chamber installed in the Nova system has ten beams which are situated so that no beam is fired into another. A nuclear-fusion reaction that takes place between the nuclei of a gas, especially hydrogen, heated to a temperature of several million degrees. Such conditions exist in the sun and stars, in a hydrogen bomb, and on a microscopic scale inside the Nova target chamber. Tokamaks were first built in Russia. The isotope of hydrogen having one proton and two neutrons in its nucleus, tritium is made from lithium.
Collimated light is light brought into line as in a laser beam.
