Description
Safe dumping of the LHC beam relies on accurate tracking of the LHC
beam energy, since the strength of the dump system elements must
scale with the beam energy to obtain the correct extraction
trajectories. The LHC Beam Energy Tracking System (BETS) is
responsible for the generation of the kick strength reference
signals w.r.t. the beam energy of the extraction kicker high voltage
generator power supplies. The system also performs continuous
surveillance of the charging voltage of the different circuits
within the high voltage generators and generates a dump request if
the measured values are not within predetermined tolerance windows
relative to the beam energy. In addition, the BETS will provide the
calculated beam energy value to Safe LHC Parameters system (SLP) for
the generation of the Safe Beam Flag signal and the distribution to
other users. The architecture of the BETS, based on a modular
approach, will be presented and the functionality of the different
components included within the system described. Protection against
possible failures within the BETS system itself will be discussed in
more detail. Finally, validation tests of the complete BETS
scheduled in 2006 in the SPS will be presented.
