LHC electron cloud studies – Apr 2003

Secondary electron yield (SEY) model

Fig. 1 Secondary electron yield model as described in [1]

Fig. 1_zoom. Details of the simulated SEY at low incident electron energy

The model for the LHC Build Up Simulations is described in the CERN code comparison web page: [1] http://wwwslap.cern.ch/collective/ecloud02/ecsim/modelbu.html

Note: CERN measurements by R. Cimino and I. Collins show 100% reflectivity at zero energy, with a SEY closed to the curve shown in red.

LHC e- line charge and power deposition for different electron reflectivity models

LHC field free region. Electron line density in electrons/meter and power deposition in W/m for three different reflectivity behavior at low incident electron energy. Note: CERN measurements by R. Cimino and I. Collins show 100% reflectivity at zero energy.
