No generally accepted definition for Internal Transport Barriers (ITBs) exists. Vaguely speaking, the term refers to a radially localized reduction of transport for ions or electrons. | No generally accepted definition for Internal Transport Barriers (ITBs) exists.

ITBs can be actively produced by modifying the current profile using external means. | |||

They are used to improve plasma confinement and stability properties, and to drive additional bootstrap current. Therefore, they are included in some alternative operational scenarios for [[ITER]]. | |||
