 Upgrades to the Infrastructure and Management of the Operator Workstations and Servers for Run 2 of the CERN Accelerator Complex / Bland, Alastair (CERN) ; Page, Stephen (CERN) The Controls Group of the CERN Beams Department provides more than 400 operator workstations in the CERN Control Centre (CCC) and technical buildings of the accelerators, plus 300 servers in the server room (CCR) of the CCC. During the long shutdown of the accelerators that started in February 2013, many upgrades were done to improve this infrastructure in view of the higher-energy LHC run.

 A Generic Timing Software for Fast Pulsed Magnet Systems at CERN / Chanavat, Christophe (CERN) ; Arruat, Michel (CERN) ; Carlier, Etienne (CERN) ; Magnin, Nicolas (CERN) At CERN, fast pulsed magnet (kicker) systems are used to inject, extract, dump and excite beams. Depending on their operational functionalities and as a result of the evolution of controls solutions over time, the timing controls of these systems were based on hybrid hardware architectures that have resulted in a large disparity of software solutions.

 The New Modular Control System for Power Converters at CERN / Di Cosmo, Matteo (CERN) ; Todd, Benjamin (CERN) The CERN Accelerator Complex consists of several generations of particle accelerators, having around 5000 power converters supplying regulated current and voltage to normal and superconducting magnets. Today around 12 generations of legacy control system types are in operation in the accelerator complex, having significant impact on operability, support and flexibility for the converter controls electronics.

 Upgrade of the Trigger Synchronisation and Distribution System of the Beam Dumping System of the Large Hadron Collider / Magnin, Nicolas (CERN) ; Antoine, Alain (CERN) ; Carlier, Etienne (CERN) ; Chareyre, Vincent (CERN) ; Gabourin, Stéphane (CERN) ; Patsouli, Anastasia (CERN) ; Voumard, Nicolas (CERN) Various upgrades were performed on the Large Hadron Collider (LHC) Beam Dumping System (LBDS) during Long Shutdown 1 (LS1) at CERN, in particular to the Trigger Synchronisation and Distribution System (TSDS): A redundant direct connection from the LHC Beam Interlock System to the re-trigger lines of the LBDS was implemented, a fully redundant powering architecture was set up, and new Trigger Synchronisation Unit cards were deployed over two separate crates instead of one. These hardware changes implied the adaptation of the State Control and Surveillance System and an improvement of the monitoring and diagnosis systems, like the various Internal Post Operation Check (IPOC) systems that ensure that, after every beam dump event, the LBDS worked as expected and is 'as good as new' for the next LHC beam.
