Abstract / Description:The Superconducting Proton Linac (SPL) at CERN is
part of the planned injector upgrade of the LHC. Initially
used at low duty cycle as LHC injector it has the potential
to be upgraded as a high power proton driver for neutrino
physics and/or radioactive ion beams.
In this paper the influence of the beam parameters on the
build-up of Higher Order Mode (HOM) voltages is studied
together with their interaction on the beam. For this purpose
we use bunch tracking simulations in the longitudinal
and transverse plane in order to define Beam Break-Up
(BBU) limits. These simulations take into account changing
values for the HOM frequency spread and are carried
out using various distances between the HOM frequencies
and the main machine lines.
