	The TCDQ diluters are installed as part of the LHC beam dump system to protect the Q4 quadrupole and other downstream elements during a beam dump that is not synchronised with the abort gap, or in case of erratic firing of the extraction kickers. These diluter elements installed during Run 1 were compatible with beam up to 60 % of the nominal intensity, which was insufficient for the second run of the LHC. This paper describes the requirements for the upgrade done during the First Long Shutdown (LS1), to make the TCDQ compatible with the full 7 TeV LHC beam at intensities required for the future runs of the machine. Subsequently the mechanical design changes, implementation and commissioning of the TCDQ are reported.

THPF086	A New Hardware Design for PSB Kicker Magnets (KSW) for the 35 mm Transverse Painting in the Horizontal Plane	3890

	The changeover from Linac2 to Linac4 in CERN’s injector chain will allow increasing the injection energy into the PS Booster from 50 MeV to 160 MeV. Transverse phase space painting will be performed in the horizontal plane, by means of four stacks of four KSW kicker magnets. The KSW magnets are located outside the injection region and will produce a 35 mm closed orbit bump, with falling amplitude during the injection to accomplish transverse phase space painting to the required emittance. New magnets with two different types of coils are being built using the existing design. The magnets are made of two halves, which are assembled together around a vacuum ceramic chamber. In order to reduce the beam impedance, the ceramic chamber is internally coated by a thin titanium layer. A new multiple-linear waveform generator has been developed to provide the high flexibility in the KSW kicker magnets current decay to fulfil the requirements of all the different users (LHC, nTOF, ISOLDE, CNGS, etc.).

CERN’s Proton Synchrotron Booster (PSB) is undergoing a major upgrade program in the frame of the LHC Injectors Upgrade (LIU) project. During the first long LHC shutdown (LS1) some parts of the upgrade have already been implemented, and the machine has been successfully re-commissioned. More work is planned for the upcoming end-of-year technical stops, notably in 2016/17, while most of the upgrade is planned to take place during the second long LHC shutdown (LS2).
