Summary of the Workshop on Electric Fields, Structures & Self-Organisation in Magnetized Plasmas (EFTSOMP) 2009. 6-7 July, 2009, Sofia, Bulgaria

This 2-day workshop was held as a traditional satellite meeting of the 32nd European Physical Society Conference on Plasma Physics, in Sofia Bulgaria. 20 participants attended the meeting which was organized as invited talks and oral presentations in six sessions covering plasma turbulence, self organisation, H-mode and ELMs. The timeliness of the workshop was underlined by the presentation of Carlos Hidalgo, chairman of the European Fusion Development Agreement (EFDA) Transport Topical Group, on the TG's pilot project on Long-range correlations and transport barrier physics. This is a focused action of the TG to address the question of understanding the role of long-range correlations when approaching plasma conditions in which the edge transport bifurcation develops. The project has three elements: shear flow and long range correlation measurements in Ohmic (L-mode) and biased plasmas, study of the development of long-range correlations during spontaneous H-mode transitions and simulations. The experiments are supported by special diagnostic developments, including probes, Beam Emission Spectroscopy (BES), reflectometry, fast visible cameras and Heavy Ion Beam Probe (HIBP). Several of these developments aim at duplicating systems to perform measurements at remote locations on the same device.
