      abstract     = {A set of discharges performed with the JET ITER-like wall
                      is investigated with respect to control capabilities on
                      tungsten sources and transport. In attached divertor
                      regimes, increasing fueling by gas puff results in higher
                      divertor recycling ion flux, lower divertor tungsten source,
                      higher ELM frequency and lower core plasma radiation,
                      dominated by tungsten ions. Both pedestal flushing by ELMs
                      and divertor screening (including redeposition) are possibly
                      responsible. For specific scenarios, kicks in plasma
                      vertical position can be employed to increase the ELM
                      frequency, which results in slightly lower core radiation.
                      The application of ion cyclotron radio frequency heating at
                      the very center of the plasma is efficient to increase the
                      core electron temperature gradient and flatten electron
                      density profile, resulting in a significantly lower central
                      tungsten peaking. Beryllium evaporation in the main chamber
                      did not reduce the local divertor tungsten source whereas
                      core radiation was reduced by approximately $50\%.$},
