19 | // Class for a simple description of the LHC. | |
20 | // The LHC is described by two beams, | |
21 | // the interaction regions and the | |
22 | // beam loss processes. | |
23 | // Run paramters can be set in order to simulate the time evolution | |
24 | // of emittance, number of particles per bunch and luminosity. | |
