Fast extraction from SPS LSS4 for the LHC and NGS projects

The proton and lead ion beams for the anti-clockwise ring of the LHC will be extracted from the SPS in LSS4 and transferred to LHC point 8 via the transfer line TT40-TI8. A conventional single turn 'fast' extraction will be used. The same extraction channel may be used to transfer protons to a neutrino target for the proposed long baseline Neutrino to Gran Sasso (NGS) project. The planned layout for the extraction channel in LSS4 now has the extraction septum in SPS half period 418, and is outlined for both fast-pulsed and DC septum designs.
