(under subclass 133) Subject matter for removing particles at the extremities of the given volume which would otherwise (a) impact on means (i.e., chamber) physically containing the volume, or (b) enter the given volume and mix with the plasma.
(1) Note. The difference between the divertors of this subclass type and the limiters and liners of subclass 136 is that the divertors remove the particles, as by means of gaseous flow or magnetic fields, whereas limiters and liners are structural elements which trap or absorb the particles.
