Dear Colleagues, The International Conference on Linear Colliders (LCWS '04), to be held in Paris on April 19 - 23, will include parallel sessions on Accelerator Physics Topics. We anticipate that the sessions will include both talks on selected LC accelerator subjects by experts and short presentations of recent work. If you would like to speak there, we ask that you contact us as soon as possible. Contributions from particle physicists engaged in LC accelerator research are particularly welcome. More information about the conference is available at http://polywww.in2p3.fr/LCWS2004 . Sincerely, The "Accerator Physics Topics" Session Organizers Tsutomu Nakanishi ([log in to unmask]) Grahame Blair ([log in to unmask]) Ritchie Patterson ([log in to unmask])
