Query: Upgrades Of the SPS, Transfer Line and LHC Injection Protection Devices
  For the HL-LHC Era   The challenging High Luminosity LHC (HL-LHC) beam requirements will lead in
the future to unprecedented beam parameters along the LHC injector chain. In
the SPS accelerator these requests translate into about a factor two higher
intensity and brightness than the present design performance. In addition to
the challenge of producing and accelerating such beams, these parameters affect
the resistance of the existing equipment against beam impact. Most of the
protection devices in the SPS ring, its transfer lines and the LHC injection
areas will be put under operational constraints which are beyond their design
specification. The equipment concerned has been reviewed and their resistance
to the HL-LHC beams checked. Theoretical and simulation studies have been
performed for the SPS beam scraping system, the protection devices and the dump
absorbers of the SPS-to-LHC transfer lines, as well as for the LHC injection
protection devices. The first results of these studies are reported, together
with the future prospects.
