Currently this SEWG is mostly machine oriented Very little on fundamental retention mechanisms Is this good? Should the focus be changed in the future?

3. K. Schmid, SEWG meeting 19-20.07.2010 Some statistics Work done by 8 associations 15 Baseline support tasks 15 Priority support tasks

4. K. Schmid, SEWG meeting 19-20.07.2010 Required reports Baseline & Priority support tasks: October 2010: Annual meeting of the EU TF on PWI Presentation of the SEWG activities 2010 by the SEWG leaders Supply a couple of slides presenting your 2010 work by September Priority support tasks: A written report on the 2010 activities within your EFDA task Individual contributions should be sent to me by November

5. K. Schmid, SEWG meeting 19-20.07.2010 Meeting goals 1.) Present current status of the individual EFDA tasks 2.) Identify problems or shortcomings in current tasks 3.) Propose new points of interest that may require additional research
