On the evolution of profiles and fluctuations towards the L-mode density limit in ASDEX Upgrade

The maximum achievable density in a tokamak is restricted by the so-called density limit. In this contribution, we observe that a MARFE precedes the final chain of events leading to disruption in ramp up L-mode discharges, resulting in strong power dissipation and plasma cooling, which likely makes...
