Space Charge induced Trapping: aim of the
code benchmarking
The aim of the code benchmarking is to confirm the
space charge induced trapping of particles in a bunch
during long term storage.
Numerical investigation and experiment at the CERN-PS have been
performed in 2002-2003 (see references) but no other code has
been used to confirm the mechanism and to reproduce the
measurements.
In order to make a code benchmarking we use the SIS18 lattice.
An external sextupole is added in the linear lattice
to create a 3rd order resonance.
