It is a well know fact that the eddy currents generated in the
vacuum chambers of the pulsed dipoles of the booster produce a
heating of the vacuum chamber and a time dependent sextupolar
field [
1]. In this paper, we review the effect of this
sextupolar field in the SLS booster, and estimate the strength of
the sextupoles used to compensate the chromaticity, and review the
differences between the SLS booster lattice and a more traditional
one.
