No. 38 (2005): Bunch compressors, important parts of the linac-based free electron laser (FEL) and the International Linear Collider (ILC)

Issue Editor: I. S. Ko, Editor-in-Chief: W. Chou

1. In this Newsletter, there is a special session dedicated to the electron bunch compression. This topic becomes very important in the field of linac-based free electron lasers and eventually ILC linac as well. Detailed mechanism of electron bunch length compression is covered by M. Dohlus and T. Limberg of DESY, and P. Emma of SLAC. Microbunching instability due to bunch compression which degrades FEL lasing is described by Z. Huang and J. Wu of SLAC, and T. Shaftan of BNL. I thank all authors for their contributions to this issue of Newsletter. I miss the third article on the bunch compression scheme for ILC that was not submitted on time. It will appear in the next issue of the Nesletter.

   In the ILC section, we have a detailed plan for ILC School scheduled on May 19-27, 2006 at Sokendai, Hayama, Japan.

   There are several activity reports including one from South Africa. We have an excellent and rare chance to hear voices from African physicists. One interesting issue is a suggestion of the creation of International Science Center including African Synchrotron Radiation Facility, which reminds me SESAME project.
