Attendees: KEK: S. Fukuda (Chair), T. Shidara FNAL: J. Reid, O. Nezhevenko, B. Chase, C. Jensen SLAC: C. Adolphsen, R. Larsen The agenda and all discussion notes as well as these minutes are posted at: http://ilcagenda.linearcollider.org/conferenceDisplay.py?confId=2051 Shigeki Fukuda chaired the meeting. 1. Discussion of Planning for upcoming HLRF EDR Kickoff Meeting (KOM) of October 1-3, 2007 at SLAC and by Webex Shigeki presented the slides attached to item 1 on the presentations. Suggestions included: -Participants from Asia would be A. Yamamoto (PM), S. Fukuda (Co-Convener), and M. Akemoto, plus Web participants who may also give presentations. 2. Proposed Talks: ** Opening talk by A. Yamamoto on HLRF Charge from GDE management, relationships with technical, global and accelerator systems; HLRF interfaces ** Status talks from three regions (a number of names were discussed) Marx Klystron Distribution AC Power Distribution Interlocks and Controls Lab overviews of R&D (KEK, DESY) 3. Proposed Discussion Topics: ** Work Package plans, integration with regional plans, collaboration for ACD among regions ** Specific examples of coordination of WP's: Marx, Power Distribution (PDS), etc. ** Cost estimate reviews: BCD methodology for all major items, completeness, industry quotes ACD Cost status ** Industrialization plan, procurement plan/options ** Regional collaboration, procurement differences/issues ** Time Schedule Major milestones for HLRF during EDR period & beyond 4. Next on the agenda were status reports from Shigeki, one on the Toshiba 10MW tube destined for SLAC and another on Bouncer Modulator progress with industry. The 10 MW tube is coming along nicely but Toshiba wants to slip delivery by 1 month until October. This is not a problem with Adolphsen's schedule for the new L-Band station. Shigeki showed results from the new 2nd Nichicon BCD bouncer modulator which looked very good. He also showed a prototype of another unit from a KEK-TMEIC collaboration based on a new device called an IEGT (Injection-Enhanced Gate Transistor) made by Toshiba. The unit was tested at KEK and performed well in power tests. The prototype did not include the bouncer. 5. Possible Participants in HLRF EDR KOM Besides those already mentioned from KEK, proposed speakers were suggested for various technical talks. Some will require visas and will need invitation letters. The talks will also be open to web participants so hopefully we'll have a good international representation. A first cut at an agenda will be reviewed on August 16th during the ML Webex meeting. *****NOTE: This meeting falls on our normal TV meeting time so next week's regular HLRF meeting is cancelled.**** 6. Waveguide Distribution Cooling - continued The results of previous work by Nantista and comments and additional work by O. Nezhevenko and V. Katalev are posted by Nantista's name on the meeting site. These show a reasonable convergence of the results of phase shift due to waveguide heating without water cooling channels. Parties seem to agree that from the standpoint of phase shift the LLRF can easily do the necessary corrections so water cooling is not necessary for that reason. However the other consideration is human occupancy of the tunnel and that may require the cooling to meet health and safety requirements. Next meeting: Thursday August 23rd 3 PM PDT Respectfully, Ray Larsen
