What is divertor or diverter?

A divertor or diverter is a device used in fusion reactors to manage the plasma that is created during the fusion process. The plasma is a highly concentrated, hot gas made up of charged particles that are held together by magnetic fields. The divertor is designed to control the flow of plasma and prevent it from damaging the walls of the reactor.

The divertor is typically a set of plates or fins that are placed inside the reactor chamber. These plates are cooled by water or other coolants to prevent damage from the hot plasma. The plasma is directed towards the divertor, where it is either absorbed or redirected away from the walls of the reactor.

There are two main types of divertors: the poloidal divertor and the toroidal divertor. The poloidal divertor is located at the bottom of the reactor and intercepts the plasma as it travels along the magnetic field lines. The toroidal divertor is located on the sides of the reactor and intercepts the plasma as it moves around the reactor.

The divertor is an important component in fusion reactors, as it helps to protect the walls of the reactor from damage and prolong the life of the reactor. Additionally, the divertor helps to control the flow of plasma, which is critical for achieving the high temperatures and pressures needed for nuclear fusion to occur.
