This a volunteer computing project that uses Internet-connected computers to advance Particle and Accelerator Physics. Participate by downloading and running a free program on your computer. By default, you can run the classic LHC@home application Sixtrack, for simulations of accelerator physics, and help researchers at CERN to improve the LHC.

Other LHC@home simulations that utilizes virtualization to run applications for Theory and experiment simulations for ATLAS, CMS and LHCb are also available.

Please note that some of the applications on LHC@home require Virtual Box to be installed. Please visit the LHC@home information site for more information. If you have any problems or questions please visit the Message Boards, Questions and Answers and FAQ.
