		\im Low density discharges ($ n_e \sim 10^{18} \ \mathrm{m}^{-3} $) in GOLEM  exhibit an ADI, which is: i) manifested by 3 spikes of the $ \mathrm{U}_{\mathrm{loop}} $ i) accompanied by an increase of HXR followed by an increase of the line average density $ \rightarrow $  signature of an enhanced plasma-wall interaction
		\im Edge plasma analysis  by a nearly exact direct masurement of the plasma  potential with BPP.
