JET status for 2008/09:New capabilities, operating schedule and research focus
23rd IEA LTA ExCom Meeting M. L. Watkins 2 (21) GA, San Diego, USA 3-4 June 2008
JET since LTA ExCom22, Naka, 2007
• Successfully completed 2007 Shutdown, including assembly and installation of enhancements (ITER-like ICRH Antenna, High Frequency Pellet Injector,.)
• Successfully completed 2008 Restart of operations, including first tests of ITER-like ICRH Antenna, High Frequency Pellet Injector
• Successfully elaborated EFDA-JET 2008 Experimental Campaigns, including preparations for ITPA High Priority Coordinated Experiments (> 30% of JET programme time in 2008)
• Completed (almost) Experimental Campaigns C20a&b comprising 38 S/T days (two shift operation) during Spring 2008 (7 April to 6 June 2008)
• Conducted R&D, procured components and buildings for enhancements for installation during 2009/10 (ITER-like Wall, NB Power Upgrade,…)
• Conducted Fusion Technology Tasks using the JET Facilities
23rd IEA LTA ExCom Meeting M. L. Watkins 3 (21) GA, San Diego, USA 3-4 June 2008
Some successes of 2007/2008• ELMs ameliorated successfully (radiative edge, external magnetic
perturbations)• TF Ripple studies• High N (~3) obtained for long pulse (7s)• Edge control and stability of AT scenarios• Material migration and fuel retention quantified• Large ELMs (>0.6MJ energy drop) lead to high radiation (>50% of ELM
energy drop) and low power (~10%) to outer limiter surfaces• Ion temperature critical gradient length (“threshold”) determined • Analysis of inward momentum pinch• ITER-relevant RF and LH coupling achieved• High current (3.5MA) at high delta achieved• High Level Commissioning of ITER-like ICRH Antenna• High Level Commissioning of High Frequency Pellet Injector• Optimisation of ELM control with Resonant Magnetic Perturbations• Rotation Braking• Start-up and current ramps for ITER
23rd IEA LTA ExCom Meeting M. L. Watkins 4 (21) GA, San Diego, USA 3-4 June 2008
Elaboration of JET 2008Experimental Programme
General Planning Meeting: 19-23 November 2007• No specific Call for proposals for experiments, but open channel for new experiments
maintained through Task Forces, now and during Campaigns• Ideas for experiments started by being discussed in Task Force meetings• Scientists who might expect to be involved in JET 2008 Campaigns invited to
participate in General Planning MeetingThis approach found to be more effective for all users of JET Facilities
to agree on main and back-up experiments in detail
Headlines for JET 2008 Experimental Programme• High level commissioning and full scientific exploitation of new systems and issues
that could impact on the design of ITER components• Qualification of integrated operating scenarios for ITER• Physics issues essential to the efficient exploitation of ITERGuidelines to focus JET 2008 Scientific Programme• Heat Load and ELM Control• Pedestal and L-H transition• Core confinement• Fuelling and Particle control• Stability and control at high pressure• RF power optimisation
