“…During 2011 extensive measurements were done after the source and after the LEBT with the aim of preparing the RFQ commissioning and validating the simulation tools, indispensable for future source upgrades. The measurements have been thoroughly simulated with a multi-particle code, including 2D magnetic field maps, error studies, steering studies and the generation of beam distribution from measurements. …”

“…Two types of sensors, based on two different technologies are under development and study at CERN: the capacitive sensor (cWPS) is already in use for the monitoring of the position of the low beta triplets in the LHC and the optical sensor (oWPS) is currently under development with Open Source Instruments. The cWPS had to be upgraded in order to reach the specifications required by the CLIC alignment. …”

“…First, by increasing of a factor five the LHC luminosity in ten years from now, and then by increasing its energy by a factor two or more, on the horizon of the next twenty years. These LHC upgrades, in luminosity and energy, will be the super-exploitation of the CERN infrastructure and is the best investment that the HEP community can make in order to extend the boundary of our knowledge at an affordable cost.…”

“…One key component of machine protection, the Beam Interlock System (BIS), was designed to interface critical systems around the accelerator chain, provide fast and reliable transmission of beam dump requests and trigger beam extraction in case of malfunctioning of equipment systems or beam losses. Numerous upgrades of accelerator and controls components during the Long Shutdown 1 (LS1) are followed by subsequent software updates that need to be thoroughly validated before the restart of beam operation in 2015. …”
