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. ICAP’15 is jointly organized by 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. The conference venue will be the Howard Johnson Plaza Hotel, 595 Jiu Jiang Road, Shanghai (http://www.howardjohnson-hotels.com/home.html). With a population of more than 24 million as of 2013, Shanghai is the largest city in the People's Republic of China. Situated on the banks of the Yangtze River Delta in Eastern China, it is a global financial center and with 2500 berths, is the busiest container port in the world. Shanghai is a popular tourist destination renowned for its historcal landmarks such as The Bund, City God Temple and Yu Garden as well as the financial district of Lujiazui with its extensive skyline. In its metropolis, one finds a unique blend of the traditional, oriental with that of the modern, western culture which makes the visit to Shanghhai such memorable experience.
