The evolution of Zeff(r) profiles in Jet plasmas

Description

The temporal evolution of the average ion charge in JET is investigated. The experiment is performed by using a 15-channel poloidal array to measure the visible bremsstrahlung emission. The impurity behavior during ohmic, neutral beam injection and ICR heating is analyzed. It is shown that under all conditions, recycling at the plasma edge plays an important role. Moreover during neutral beam injection in limiter discharges, the average ion charge decreases, but its profile shape remains unchanged
