Conceptual design of an off-momentum collimation system in the CERN Super Proton Synchrotron for High-Luminosity Large Hadron Collider proton beams / Patecki, Marcin (CERN) ; Mereghetti, Alessio (CERN) ; Mirarchi, Daniele (CERN) ; Redaelli, Stefano (CERN)
The CERN accelerator complex is undergoing an upgrade in order to meet the requirements of the High-Luminosity Large Hadron Collider (HL-LHC). One of the key needs is to increase the intensity of beams injected into the LHC from the current $1.15 \times 10^{11}$ to $2.3 \times 10^{11}$ $p^+ $ /bunch. [...]

CERN Secondary Beamlines Software Migration Project / Gerbershagen, Alexander (CERN) ; Banerjee, Dipanwita (CERN) ; Bernhard, Johannes (CERN) ; Brugger, Markus (CERN) ; Charitonidis, Nikolaos (CERN) ; D'Alessandro, Gian Luigi (CERN ; Royal Holloway, U. of London) ; Gatignon, Laurent (CERN) ; Montbarbon, Eva (CERN) ; Peres, Inbal (CERN ; Technion) ; Rae, Bastien (CERN) et al.
The Experimental Areas group of the CERN Engineering department operates a number of beamlines for the fixed target experiments, irradiation facilities and test beams. The software currently used for the simulation of the beamline layout (BEATCH), beam optics (TRANSPORT), particle tracking (TURTLE) and muon halo calculation (HALO) has been developed in FORTRAN in the 1980s and requires an update in order to ensure long-term continuity.
