Spencer’s input to ILC Magnet System Planning for EDR

1. Spencer’s input to ILC Magnet System Planning for EDR Cherrill Spencer SLAC & ILC Magnet Systems Group 12th July 2007 weekly meeting

2. Suggested organization for the EDR phase, as of 1st July. The GDE exec met in Rome past 2 days to discuss EDR org- may have changed. No boxes for Magnets, Vacuum, System Engineering, etc EDR Planning Cherrill Spencer

3. Cherrill’s opinion on the EDR organization • Others, more important than I, have complained, as I do, about the absence of any technical systems boxes in the org chart. • Tech Systems groups have already been formed and learnt how to work with each other achieved much technical detail for the RDR, seems counter-productive to disband them at this stage. • All Tech Systems need system-wide standards and central planning, not least Magnets and Power supplies. EDR Planning Cherrill Spencer

4. Cherrill’s opinion continued • Even Jonathan Dorfan made a suggested org chart for the ILC with technical systems explicitly listed, and handed it to Barish- we don’t know what happened to this idea (maybe after the Rome meeting the org chart will change!) • FUNDING NEEDS TO BE ASSIGNED DIRECTLY TO THE TECHNICAL SYSTEMS, else engineers will not be made available by any national labs anywhere to work on the ILC EDR Planning Cherrill Spencer

5. Info on our new boss: Akira Yamamoto, from today’s ILC Newsline • Despite his quiet, down-to-earth appearance, Yamamoto is a very resolute man with devotion and passion for physics. Mark Ross, who will be part of the ILC project management team with Akira, says “He is the man who makes the point. He wants to make everything clear. That makes him a great project manager.” I am also sure that Akira's strong background in project management will be a great help for the ILC community, especially to follow the technical timeline. • When he comes up against a difficult situation, he doesn't shout. Instead, he is known for a particular expression on his face that actually forces the team members to work harder, making them feel pressed to get overcome the problems. It might take some time for other collaborators to become familiar with this work style. Nevertheless, let's keep working hard and hope not to see him make this famous face!

6. Items Cherrill willing to work on in immediate future , pg 1/2 Important items remaining from RDR; e.g., * FMEA studies YES * Large solenoids * Magnet stands (other than DR) * Cost methodology YES * Magnet Integration * Design standards YES * Material standards YES * Minimization of styles YES * Design reviews YES EDR Planning Cherrill Spencer

7. Items Cherrill willing to work on in immediate future pg2/2 * 'Global Facilities' * Conventional test and storage * Cold Test facility * Magnetic measurement systems * Reliability YES * Component studies YES * 'Life' tests of magnets YES EDR Planning Cherrill Spencer

8. Draft Plan for doing a FMEA on several magnets. STATUS 9. Start by studying (in own time) the drawings of the chosen magnet to identify how failures might be initiated in requirements or design stages, or how loss of its function may occur during other stages(though one might not discover the incident until its turned on!)– write down & bring to meeting. Consider how often this failure mode occurs- look up magnet failure data at your lab. Talk to other magnet experts not on team to get their failure horror stories. 10. Team meets and starts to fill in the FMEA worksheet– come to consensus on O, S and D rankings for each failure mode. 11. Keep going until all possible failures listed. EDR Planning Cherrill Spencer
