One avenue towards an integrated H-mode regime suitable for standard operation on ITER is development of well-confined states with intrinsically small ELMs. Significant progress has been made with the "Type II" and "mixed" regimes on ASDEX-U and JET, high bp "grassy" regime on JT-60U and JET, "EDA" H-mode on Alcator C-Mod and JFT-2M, and "QH"-mode on DIII-D and ASDEX-U (see eg [1,2] and references therein). An important feature these all have in common is an increase in continuous edge turbulence compared to usual intervals between Type I ELMs, which mediates steadier exhaust through the pedestal region. The aim in the present study is to open a systematic examination of edge fluctuations in ELM-free periods on JET, in order to clarify their evolution towards the former benign properties. We compare behaviour in "standard" cases with plasmas coming progressively closer to the conditions of C-Mod EDA and ASDEX-U Type II pedestals.
