Behavior of deuterium particles in the divertor region and sketch of the high resolution spectrometer Deuterium ions in the divertor region are accelerated toward the divertor plate by an electric field formed at the surface of the plate, and collide against it. Some of the ions that collide with the divertor plate are reflected into the plasma as neutral deuterium atoms. Deuterium molecules with an energy equivalent to the temperature of the divertor plate are also emitted by collision and return to the plasma. These atoms and molecules again become deuterium ions in the plasma through charge-exchange, dissociation and ionization reactions, namely recycling processes are repeated many times in the plasma.
