The steering program YASP was introduced in the LEIRinjection as well as the extraction lines in 2016 to correctthe trajectories with well-known model based correctionalgorithms such as MICADO or SVD. In addition a YASPconfiguration was prepared to correct the extraction linetogether with the first turn of the PS. [...]

The LHC performance during the proton-lead run in 2016 fully relied on a permanent monitoring and systematic improvement of the beam quality in all the injectors. The beam production and characteristics are explained in this paper, together with the improvements realized during the run from the source up to the flat top of the LHC [...]

Beam Loss in the Low Energy Ion Ring (LEIR) in the Light of the LHC Injector Upgrade for Ions (LIU-Ions)
/ Bodendorfer, Michael (CERN) ; Angoletta, Maria Elena (CERN) ; Axensalva, Jerome (CERN) ; Manglunki, Django (CERN) ; Pasinelli, Sergio (CERN)
For the LHC injector upgrade, the Low Energy Ion Ring (LEIR) is requested to deliver twice the intensity per extraction compared to the last Pb⁵⁴⁺ ion run in 2013 (i.e. 2 bunches of 5.5·10¹⁰ charges). [...]

The renewed availability of heavy ions at CERN for the needs of the LHC programme has triggered the interest of the fixed-target community. The project, which involves sending several species of primary ions at various energies to the North Area of the Super Proton Synchrotron, has now entered its operational phase. [...]

Probing intensity limits of LHC-Type bunches in CERN SPS with nominal optics
