We are all extremely pleased with the outcome and I wish to thank the Task Force Leaders, Task Force members and the Associations for the extraordinary amount and quality of the work they have done in preparation of the meeting.
George Sips, organiser of the meeting

The second General Planning Meeting took place on November 15-19th. The planning of the experimental campaigns after the current shutdown of JET is coming to an end. This meeting was set up to review constraints for the upcoming sets of experiments. Additionally the received experimental proposals were reviewed.
So far, three campaigns are planned providing a total of 159 operational days, assuming four operational days per week.
Sixty off-site contributors participated in the meeting, including representatives from ITER and Fusion for Energy. The two Task Forces, E1 E2, set up last year, completed a large amount of preparatory work. The careful preparation was worthwhile doing as the meeting went smoothly and the targets were fully hit.
In the past, individuals or associations submitted separate proposals. For the first time interested parties formed implemented working groups and elaborated on the proposals collectively.

The new procedure was well accepted: Physicists from the various Associations participated in 14 such working groups. The outcome of the vivid discussions within these groups was extremely fruitful. Proposals were withdrawn, merged with others or revived with a different emphasise. About 200 proposals were elaborated on, much more than the planned campaigns are able to accommodate.

The finalised experimental programme takes into account that JET equipped with a full metal ITER-Like Wall is essentially a new machine. Therefore the programme follows a strategy of progressively stepping up the auxiliary heating power for testing the capabilities of the JET device. As the operating space in terms of auxiliary power and plasma parameters expands over months, more ambitious experiments can be undertaken.
The lion’s share of the programme will be the study of fuel retention and material migration, which are critically important for ITER and may still influence design choices for plasma facing components in ITER. Other essential programme elements are the re-establishment of robust ITER-relevant ELMy H-modes and hybrid scenarios. Further high performance scenario development, making use of the full Neutral Beam Heating capabilities (now up to 34 megawatts), will be pursued in 2013.
The new procedure has proofed to involve all interested parties in the process in an effective and productive way. The Task Force Leaders will now continue to finalise the timeline for Experimental campaigns.
