The CERN LHC Injectors Upgrade (LIU) seeks to reliably deliver the beams required for the High- Luminosity LHC (HL-LHC). As part of this, the Proton Synchrotron Booster (PSB) will be upgraded from 1.4 GeV to 2 GeV and will accelerate higher intensity beams. Along the transfer lines between the PSB and the Proton Synchrotron (PS) there are several D.C. operated quadrupoles which are unable to produce the gradients and field quality required for the 2 GeV HL-LHC beams. To minimise future power consumption, these will be replaced by laminated quadrupoles, operated in pulse to pulse modulation mode. Despite being installed along a transfer line, the field homogeneity requirements imposed on these magnets is very tight, requiring a homogeneity of 5x10-4 on the integrated gradient. Such strict requirements presented several issues for the design, especially when considering the space constraints which naturally apply when upgrading a pre-existing accelerator. The design and development process of these quadrupoles is summarised in this report.
