We are pleased to announce that the International Computational Accelerator Physics Conference, ICAP’15, will take place in Shanghai, China, from October 12 to 16, 2015. http://icap2015.csp.escience.cn ICAP’15 is jointly organised by the the Shanghai Institute of Applied Physics (SINAP), SLAC National Accelerator Laboratory (SLAC) and Tsinghua University, and SINAP is the host of the conference. The ICAP’15 conference will be the 12th in the conference series following meetings in La Jolla, USA (1988), Los Alamos, USA (1990), Pleasanton, USA (1993), Williamsburg, USA (1996), Monterey, USA (1998), Darmstadt, Germany (2000), East Lansing, USA (2002), St. Petersburg, Russia (2004), Chamonix, France (2006), San Francisco, USA (2009) and Rostock-Warnemünde , Germany (2012). ICAP’15 will focus on advances in Computational Accelerator Physics and their application to existing machines and future facilities. It will provide a forum and the opportunity for researchers in modeling and simulation to exchange information and discuss new ideas that benefit a wide area of accelerator science and technology. Topics of interest will include but not be limited to, computational needs and challenges, beam dynamics and electromagnetic field calculations, code development and validation, data processing and visualization, high performance computing as well as emerging technologies that will impact computing for accelerator design.
