The International Tokamak Physics Activities (ITPA) coordinates various physics activities around the world, addressing key topics important to ITER construction and operation. ITPA comprises 250 representatives from the world’s tokamak facilities. It is organised into seven topical groups, overseen by a coordinating committee. The committee met in Cadarache on July 15th -16th to discuss past year research achievements, further research necessary for ITER and future joint experiments. Currently, around 70 joint experiments are conducted under ITPA. Among the key issues discussed at the meeting was the suppression of Edge Localised Modes (ELM), for which further experimental capabilities are developing on several tokamaks.
