Description
The dynamic structural behavior of beam diluter elements TCDS (LHC) and TPSG (SPS), protecting the extraction
septum magnets in the event of an asynchronous firing of the extraction kickers, has been studied. The
deposited energy densities, estimated by the high-energy particle transport code FLUKA, were converted
to internal heat generation rates according to the time dependence of the extracted beam. The transient response
to this thermal load was obtained by solving the power deposition and subsequent structural deformation by
using the spectral-element code ELSE.
This presentation gives a short overview of the used method and descibes the spectral-element code ELSE.
Furthermore we presents the results of the TCDS and TPSG analysis and finally conclude with some thoughts
on the materials and numerical simulations.
