LHC @ home (also called LHC @ home 1.0 , LHC @ home 2.0 , Test4Theory and SixTrack ) is a volunteer computing project that simulates the passage of particles through a 27 km long particle accelerator . This is intended to optimize the Large Hadron Collider . It runs under BOINC , a platform for distributed computing projects.

This particle accelerator ( Large Hadron Collider ) was put into operation in September 2008 by the research institute CERN .

The LHC @ Home Client simulates 10,000, 100,000 or 1,000,000 passes of 60 particles through the particle accelerator, which corresponds to 1 second, 10 seconds or 100 seconds in real time. The program calculates whether the particles could remain stable in orbit or hit the wall of the vacuum tube and thus damage the LHC. The results are used to check the stability of the particles in the LHC and provide data for adjusting the magnets.

On September 29, 2004, the project went into official operation. In the initial phase, the aim of CERN was to gain 50,000 users within 50 days. As a small incentive to participate, users were given away daily CERN T-shirts, and on October 18, 2004 an edition of the anniversary book “Infinitely CERN - Memories from 50 years of research”.

Although the project missed its target (in November 2005 a good 21,000 participants were registered), LHC @ home was continued. The server infrastructure was located at the University of London from the turn of the year 2006/2007 to August 2011 . The server infrastructure has been back at CERN since August 2011. In March 2008, the project had 88,000 registered users. The current computing power of the SixTrack project is slightly more than 30 tera FLOPs (as of September 2017), which can fluctuate depending on the daily output.

For the analysis of the data obtained in the four experiments of annual 15 petabytes the Worldwide is LHC computing grid used a form of grids . In spring 2011, another platform was started with LHC @ home 2.0, with which the data obtained by the LHC can also be analyzed by the BOINC community. The first project to run on the LHC @ home 2.0 platform is called Test4Theory .
