Adaptation of CERN Power Converter Controls for Integration into Other Laboratories using EPICS and TANGO / Page, Stephen (CERN) ; Afonso, Joao (CERN) ; Ghabrous Larrea, Carlos (CERN) ; Herttuainen, Joni (CERN) ; King, Quentin (CERN) ; Todd, Benjamin (CERN)
Modern power converters (power supplies) at CERN use proprietary controls hardware, which is integrated into the wider control system by software device servers developed specifically for the CERN environment, built using CERN libraries and communication protocols. There is a growing need to allow other HEP laboratories to make use of power converters that were originally developed for CERN and, consequently, a desire to allow for their efficient integration into control systems used at those laboratories, which are generally based upon either of the EPICS and Tango frameworks.

CERN Neutrino Cryogenic Control System Technology: From the WA105 Test Facility to the NP04 and NP02 Platforms / Pezzetti, Marco (CERN) ; Fluder, Czeslaw (CERN) ; Orlandi, Roberto (CERN)
The CERN Neutrino Platform is CERN’s undertaking to foster fundamental research in neutrino physics at particle accelerators worldwide. In this contest CERN has constructed a series of cryogenic test facilities, first of this series is the 5 tons liquid Argon detector named WA10⁵, succeeded by the 800 tons liquid Argon cryostats designated as NP04 and NP02 detectors [...]

Renovation of the SPS Personnel Protection System: A Configurable Approach / Ladzinski, Tomasz (CERN) ; Fernández Adiego, Borja (CERN) ; Havart, Frederic (CERN)
The renovation of the SPS Personnel Protection System (PPS) comprises the installation of industrial access control solutions and the implementation of a new safety instrumented system tailored to the particular needs of the accelerator. The SPS has been a working horse of the CERN accelerator complex for many decades and its configuration has changed through the many years of operation. [...]

Towards a Common Reliability & Availability Information System for Particle Accelerator Facilities / Höppner, Klaus (HITS, Heidelberg) ; Gutleber, Johannes (CERN) ; Haberer, Thomas (HITS, Heidelberg) ; Humer, Heinrich (TU Vienna) ; Niemi, Arto (CERN) ; Pasic, Kemal (HITS, Heidelberg) ; Peters, Andreas (HITS, Heidelberg)
Failure event and maintenance record based data collection systems have a long tradition in industry. Today, the particle accelerator community does not possess a common platform that permits storing and sharing reliability and availability information in an efficient way. [...]

Comparison between measured radiation levels and FLUKA simulations at CHARM and in the LHC tunnel of P1-5 within the R2E project in Run 2 / Prelipcean, Daniel
This thesis aims to benchmark the measured values of the radiation monitors employed at the European Organisation for Nuclear Research (CERN), focusing on the Large Hadron Collider (LHC), for Radiation to Electronics (R2E) applications with their simulated values using the FLUKA Monte Carlo code [...]

Description of beam instabilities in synchrotrons with wakefields and space charge forces using the circulant matrix model / Buffat, X (CERN) ; Métral, E (CERN) ; Gottlob, E (Ecole Polytechnique, Lausanne ; U. Brussels (main)) ; Høgh, C (Ecole Polytechnique, Lausanne ; Imperial Coll., London) ; Oeftiger, A (Darmstadt, GSI ; CERN) ; Pieloni, T (Ecole Polytechnique, Lausanne)
A new model for the description of beam instabilities in synchrotrons featuring wakefields and space charge forces is proposed, using the circulant matrix approach. The predictions of this model are discussed in light of past ones, with a particular emphasis on the possible mitigation of the transverse mode coupling instability by space charge forces. [...]

Considerations for a RF separated K+ beam for NA62 / Appleby, Robert Barrie (University of Manchester (GB)) ; Bernhard, Johannes (CERN) ; Dainton, John Bourke (Lancaster University (GB)) ; Burt, Graeme Campbell (Lancaster University (GB)) ; Gatignon, Lau (Lancaster University (GB)) ; Goudzovski, Evgueni (University of Birmingham (GB)) ; Jones, Rhodri (CERN) ; Lazzeroni, Cristina (University of Birmingham (GB)) ; Romano, Angela (University of Birmingham (GB)) ; Giuseppe, Ruggiero (Dipartimento di Fisica e Astronomia) et al.
In this document we assess the potential of RF separation to increase the kaon content of the high-intensity secondary beam to the NA62 experiment in the CERN North Area. The present mixed beam provides a nominal kaon flux of 45 MHz out of a total beam intensity of about 750 MHz. [...]
