  The LHC High Luminosity upgrade project includes a performance upgrade for heavy ions. One of the present performance limitations is the rise time of the SPS injection kicker system, which imposes a spacing of at least 220 ns between injected bunch trains at the operational rigidity. A reduction of this rise time to 50 ns for lead ions is requested as part of the suite of measures needed to increase the present design performance by a factor three. A new injection system based on a fast pulsed septum and a fast kicker has been proposed to fulfil this rise time requirement, and to meet all the constraints associated with the existing high intensity proton injection in the same region. This paper describes the concept and the required equipment parameters, and explores the implications of such a system for SPS operation.

  To reach a luminosity higher than 6×1027 Hz/cm2 for Pb-Pb collisions, as expected by the ALICE experiment after its upgrade during the 2nd Long LHC Shutdown (LS2), several upgrades will have to be performed in the CERN accelerator complex, from the source to the LHC itself. This paper first details the present limitations and then describes the strategy for the different machines in the ion injector chain. Both filling schemes and possible hardware upgrades are discussed.

  For the MedAustron facility under construction in Wiener Neustadt/Austria, two electrostatic septa are built in collaboration with CERN. These septa will be used for the multi-turn injection of protons and ions, as well as for the slow extraction from the synchrotron. The power supplies are designed to combine the required precision with the capability to cycle sufficiently fast to keep up with the machine cycle. The septa are being assembled at CERN. Initial tests have been done on the remote displacement system to validate its precision and communication protocol with the MedAustron control system. Subsequently the septa are tested for vacuum performance and then HV conditioned. The construction of the septa, the requirements of the power supplies and the high voltage circuit will be described. Results of the initial laboratory tests, prior to installation in the accelerator, will be given.
