Information

The 11th KEK-SLAC ISG Meeting on linear colliders (LCs) was held at KEK from Dec.16 through Dec.19, 2003. The ISG-XI meeting is a continuation of the ISG meeting series that started in early 1998. This is operated according to the MoU signed and extended by the KEK and SLAC directors for the joint research activities.
The important topics of ISG-XI are to
1. Discuss on the 8-pack project at SLAC, the status, what to be done, and what to do together, to appeal to the International Technical Recommendation Panel (ITRP).
2. Discuss together how we are going to present the X-Band technology to the ITRP.
Work Group (WG) organization:
1. WG1: Luminosity Group (Urakawa, Raubenheimer)
  1. Subgroup 1a: Beam Source (Ohmori, Sheppard)
  2. Subgroup 1b: Damping Ring (Kuroda, Wolski)
  3. Subgroup 1c: Beam Delivery (Kubo, Markiewicz)
  4. Subgroup 1d: Instrumentation (Hayano, Rossi)
2. WG2: RF Technology Group (Chin, Schultz)
