DYVACS (DYnamic VACuum Simulation) code: Calculation of gas density profiles in presence of electron cloud

The computation of residual gas density evolution in the LHC in the presence of proton beams was performed with a new simulation code called DYVACS (DYnamic VACuum Simulation). It is a modification of the VASCO code in order to take into account dynamic effects such as the electron cloud phenomenon...

description The computation of residual gas density evolution in the LHC in the presence of proton beams was performed with a new simulation code called DYVACS (DYnamic VACuum Simulation). It is a modification of the VASCO code in order to take into account dynamic effects such as the electron cloud phenomenon leading to an increase of both the electron- and the ion-induced gas desorption. Results obtained with the DYVACS code is compared to pressure measurements recorded during a typical physics fill in the Vacuum Pilot Sector of the LHC. First results show a good agreement between the calculated pressure and the experimental values.
