Agenda:

• Discussion of R&D interests of participating groups.
• Coordination with other groups (at the national labs and other "consortia").
• Plans for post-Santa Cruz LCCOM2 meeting, LCCOM2 talks.
• Proposal preparation, writing assignments.
• Plans for next phone meeting.

Discussion of projects:

Jerry Blazey (NIU):

(i) Integrated beam simulation study and (ii) electro-optic and interferometric bunch length monitor development at the proposed High-Brightness Photoinjector at Fermilab.

For the integrated beam simulation study, the plans are to hire a computational physicist on DOE money. May ask for partial support for this physicist or hardware support for computation.

Sekazi Mtingwa (MIT):

(i) Study of intrabeam scattering and other possible mechanisms of emittance growth in linear collider damping rings.

(ii) Compton scattering of intense laser on spent beams for a polarized tau or heavy flavor factory.

Plans are to travel to ATF Damping Ring at KEK for a week or two and to take another look at the theory of intrabeam scattering. Collaboration with other groups interested in investigating the use of the spent beams. Interest or possible interest at Fermilab, DESY, Hampton U., SLAC,... Will ask for support for travel, possibly graduate students.

Oleg Nezhevenko & Slava Yakovlev (Yale):

Investigation of RF breakdown and the pulse heating limit in copper cavities at 34 GHz.

Construction of a 34 GHz, 20 - 40 MW, 1 µs magnicon amplifier at Yale is near completion. Plans are to fabricate short standing wave copper structures and test at very high power (up to 700 MV/m on surface). Possible applications to linear collider upgrade, development of NLC structures, understanding of ultimate limits. Coordination with NLC and CLIC needed. Support requested for equipment, mechanical design, graduate students.

Plans for Sunday, June 30 LCCOM meeting:

• Jerry Blazey, Sekazi Mtingwa, and Slava Yakovlev or Oleg Nezhevenko will give 10-15 minute talks on proposals. Need to hear from others (including Cornell and those unable to attend this phone meeting). Please send title of talk to Joe Rogers (jtr1@cornell.edu).
• UCLC will need to put together a white paper to accompany the proposal because of the 15-page limit on the proposal proper. Each group should write a rough 1 to 2 page section by the time of LCCOM2, to allow time for changes, compilation and editing, and our own review.

Web pages:

• UCLC home: www.lns.cornell.edu/public/LC/UCLC/
• UCLC Accelerator R&D home: www.lns.cornell.edu/public/LC/UCLC/accel/

Please send anything you think we should post to Joe Rogers (jtr1@cornell.edu).

Next phone meeting
