Description
As a follow-up of the discussions initiated at the last LHC Project Workshop,
this contribution will concentrate on the aspects of the magnetic behaviour of
Trim and Tuning Quadrupoles, as well as spool and lattice Sextupoles, which
may be relevant for the machine operation. The measured magnetic hysteresis
and its possible influence on setting errors during operation will be
presented, in particular the real-time compensation of decay and snapback in
the main magnets, and the reproducibility between runs. A detailed
characterization of minor hysteresis loops is presented, to explore potential
effects on the stability of the feedback.
