New concepts for access devices in the SPS personnel protection system / Ladzinski, Tomasz (CERN) ; Havart, Frederic (CERN) ; Ninin, Pierre (CERN) ; Sanchez-Corral Mena, Eva (CERN) ; Valentini, Francesco (CERN) ; Vaxelaire, Didier (CERN)
The accelerator facilities at CERN span large areas and the personnel protection systems consist of hundreds of interlocked doors delimiting the accelerator zones. Entrance into the interlocked zones from the outside is allowed only via a small number of access points. [...]

Experience with static PLC code analysis at CERN / Tsiplaki Spiliopoulou, Christina (CERN) ; Blanco Viñuela, Enrique (CERN) ; Fernández Adiego, Borja (CERN)
The large number of industrial control systems based on PLCs (Programmable Logic Controllers) available at CERN implies a huge number of programs and lines of code. The software quality assurance becomes a key point to ensure the reliability of the control systems. [...]

Space charge driven beam loss for cooled beams and mitigation measures in the CERN Low Energy Ion Ring / Bartosik, Hannes (CERN) ; Hancock, Steven (CERN) ; Huschauer, Alexander (CERN) ; Kain, Verena (CERN)
The performance of the CERN Low Energy Ion Ring (LEIR) with electron cooled lead ion beams is presently limited by losses, which occur during RF capture and the first part of acceleration. Extensive experimental studies performed in 2015 indicate that the losses are caused by the interplay of betatron resonances and the direct space charge detuning, which is significantly enhanced during bunching.

Identification and reduction of the CERN SPS impedance / Shaposhnikova, Elena (CERN) ; Argyropoulos, Theodoros (CERN) ; Bohl, Thomas (CERN) ; Lasheen, Alexandre (CERN) ; Repond, Joël (CERN) ; Timko, Helga (CERN)
The first SPS impedance reduction programme has been completed in 2001, preparing the ring for its role as an injector of the LHC. This action has eliminated microwave instability on the SPS flat bottom and later nominal beam could be delivered to the LHC. [...]

The SPS 200 MHz TWC impedance after the LIU upgrade / Roggen, Toon (CERN) ; Calaga, Rama (CERN) ; Caspers, Fritz (CERN) ; Kaltenbacher, Thomas (CERN) ; Vollinger, Christine (CERN)
As a part of the LHC Injectors Upgrade project (LIU) the 200 MHz Travelling Wave Cavities (TWC) of the Super Proton Synchrotron (SPS) will be upgraded. The two existing five-section cavities will be rearranged into four three-section cavities (using two existing spare sections), thereby increasing the total voltage from 7 MV (I$_{RF}$ = 1.5 A) to 10 MV (I$_{RF}$ = 3.0 A).
