2. J.C. Sheppard, SLAC Americas Region September 27, 2006 2 ILC Positron TDR and R&D Collaboration Meeting 1: Oxford Thanks for coming to this meeting and a special thanks to Yury Ivanyushenkov and Glyn Northing for organizing us and to RAL for hosting us

3. J.C. Sheppard, SLAC Americas Region September 27, 2006 3 Challenge: Detailed positron systems designs and documentation are required for the ILC TDR by the end of FY09. The goal of the research and development for the ILC positron systems is to learn enough about the component and subsystem technical requirements such that the scope of the resource requests in the TDR are adequate and not excessive. Included in the R&D list are key enabling technologies. Detailed systems integration, design, and engineering for manufacture are not considered herein. Fabrication of production prototypes is to be done as part of the construction phase of the project. Introduction Discussion ILC Positron System Design and R&D Goals in Support of the TDR

4. J.C. Sheppard, SLAC Americas Region September 27, 2006 4 Goal: The goal of the Oxford ILC Positron Systems Meeting is to facilitate the development of the collaboration to design and carry out R&D in support of the ILC Positron System. It is important to organize the international activities so that the essential work for the TDR is accomplished on a priority basis and to reduce unnecessary duplication and activities not relevant to the ILC e+ system requirements Introduction Discussion ILC Positron System Design and R&D Goals in Support of the TDR

5. J.C. Sheppard, SLAC Americas Region September 27, 2006 5 Proposal: Turn our loose confederation of interested participants into a fully functioning and documented collaboration for the purpose of doing the TDR and conducting the necessary R&D in support of the TDR. It is important that we as a group take responsibility for our activities. How: Meet regularly and often: have an ILC Positron Collaboration Meeting three times a year in rotation in Europe-Japan-America Why: The other scheduled meetings (mainly GDE events) are not enough. It is important that we as a group take responsibility for our activities Introduction Discussion ILC Positron System Design and R&D Goals in Support of the TDR

6. J.C. Sheppard, SLAC Americas Region September 27, 2006 6 Formal Proposal: It is proposed that we meet formally as a group 3 times per year to discuss the status, progress, and plans for the various positron system design and R&D activities. The location of the meetings will cycle thru the three regions: Europe-Japan-US at approximately 4 month intervals, starting with the UK in September, 2006, Japan in February, 2007 and the US in June, 2007, and repeating. The meetings are typically 3 days long. The activities are divided into 9 broad topics. A topic discussion leader is named. Introduction Discussion ILC Positron System Design and R&D Goals in Support of the TDR

7. J.C. Sheppard, SLAC Americas Region September 27, 2006 7 Organization: The meeting chair will be named by the ILC positron regional GDE representatives: J. Clarke, M. Kuriki, and J. Sheppard. The chair does not actually need to be from the region. Subsequent meeting chairs should be named by the end of a current meeting. Similarly, the roster of topic leaders should be affirmed at each meeting. Topic leaders will write a short summary for each meeting with an emphasis on accomplishments and action items. The meeting chair is responsible for collecting the topical summaries and writing an overall summary of progress and expected goals by the time of the next meeting. Introduction Discussion ILC Positron System Design and R&D Goals in Support of the TDR

8. J.C. Sheppard, SLAC Americas Region September 27, 2006 8 Format: For each meeting, the meeting chair will set an agenda to cover timely issues drawn from the fixed list of topics. The meeting chair should work with the topic leaders to decide which topics to cover at a particular meeting. Not all topics need be nor should be covered at each meeting. It will be useful if all topics are covered at least once during a calendar year; some topics will be covered more than once; and different aspects of a particular topic. Introduction Discussion ILC Positron System Design and R&D Goals in Support of the TDR

9. J.C. Sheppard, SLAC Americas Region September 27, 2006 9 Topical Structure: Categorize the activities into 9 Topics. Each Topic has a named Discussion Leader who is responsible to organize the discussions (for their Topic) for the Collaboration Meetings. Topical Discussion: Each activity should be introduced as to its purpose; its contribution to e+ production; the technical feasibility; and need for design, simulation, r&d, and prototyping. The present status of each activity should be discussed including the availability of resources (people and funding), milestones, schedules, and impediments.

11. J.C. Sheppard, SLAC Americas Region September 27, 2006 11 Discussion: Every thing is open for discussion: format, discussion leaders, topics, organization, schedule, ILC Will have a session on Friday to discuss how this meeting has gone; what changes are required; what went well; what is clearly not working;……. I think that it will take about 3 meetings (1 year ) to settle out on this process Introduction Discussion ILC Positron System Design and R&D Goals in Support of the TDR
