Abstract

The proton and lead ion beams for the Large Hadron Collider (LHC) will be extracted from the Super Proton Synchrotron (SPS) in the Long Straight Sections LSS6 and LSS4, and transferred to the LHC rings 1 and 2 respectively via the transfer lines TI 2 and TI 8. Single turn ´fast´ extraction will be used in both cases. In LSS4 a new extraction system will be installed using the present design of electromagnetic septum and extraction kickers. In LSS6 the extraction system will be adapted for fast extraction using the existing septa and modified kickers. The high brightness LHC beam presents problems of protection for both existing and new equipment. Solutions are proposed and implications discussed
