      abstract     = {Since it is uncertain if ITER operation is compatible with
                      type-l edge localized modes (ELMS), the study of alternative
                      ELM regimes is an urgent issue. This paper reports on
                      experiments on JET aiming to find scenarios with small ELMS
                      and good confinement, such as the type-II ELMS in ASDEX
                      Upgrade, the enhanced D-alpha H-mode in Alcator C-mod or the
                      grassy ELMS in JT-60U. The study includes shape variations,
                      especially the closeness to a double-null configuration,
                      variations of q(95), density and beta poloidal. H-mode
                      pedestals without type-I ELMs have been observed only at the
                      lowest currents (<= 1.2 MA), showing similarities to the
                      observations in the devices mentioned above. These are
                      discussed in detail on the basis of edge fluctuation
                      analysis. For higher currents, only the mixed type-I/II
                      scenario is observed. Although the increased inter-ELM
                      transport reduces the type-l ELM frequency, a single type-l
                      ELM is not significantly reduced in size. Obviously, these
                      results do question the accessibility of such small ELM
                      scenarios on ITER, except perhaps the high beta-poloidal
                      scenario at higher q95, which could not be tested at higher
                      currents at JET due to limitations in heating power.},
