However, the underlying physics that can induce this regime is still unclear in TJ-II. Taking into account that Er and turbulence seems to play a key role in similar phenomena observed in the W7-X (enhanced confinement after pellet injection)<ref>T. Estrada et al., Nucl. Fusion 61 (2021) 046008</ref>, we propose series of PIs into plasmas with controlled density and different NBI heating powers (from low power, with 1 NBI working, to high power, with both NBI working) in order to study simultaneously the evolution of plasma potential and Er profiles (HIBPs and DR) as well as of the plasma density and its fluctations (HIBPs and DR). | However, the underlying physics that can induce this regime is still unclear in TJ-II.
