First results of the compensation of the beam-beam effect with DC wires in the LHC / Sterbini, Guido (CERN) ; Amorim, David (CERN ; Grenoble, INP) ; Bartosik, Hannes (CERN) ; Bertarelli, Alessandro (CERN) ; Bruce, Roderik (CERN) ; Buffat, Xavier (CERN) ; Carra, Federico (CERN) ; Carver, Lee (CERN) ; Cattenoz, Gregory (CERN) ; Effinger, Ewald (CERN) et al.
The compensation of the long-range beam-beam interactions using DC wires is presently under study as an option for enhancing the machine performance in the framework of the High-Luminosity LHC Project (HL-LHC). The original idea dates back more than 15 years ago. [...]

Observation of Fast Losses in the LHC Operation in 2017 / Gorzawski, Arkadiusz (CERN ; Manchester U.) ; Appleby, Robert (Cockcroft Inst. Accel. Sci. Tech. ; U. Manchester (main)) ; Fuster-Martínez, Nuria (CERN) ; Garcia Morales, Hector (CERN) ; Redaelli, Stefano (CERN) ; Xu, Chen (CERN) ; Zamantzas, Christos (CERN)
Four diamond detectors that provide beam loss measurements with time resolution in the nanosecond range were added in the vicinity of the primary collimators of the Large Hadron Collider (LHC). This is a powerful diagnostic tool that provides the unique chance to measure bunch-by-bunch losses. [...]

Diamond Monitor Based Beam Loss Measurements in the LHC / Xu, Chen (CERN) ; Dehning, Bernd (CERN) ; Domingues Sousa, Fernando (CERN) ; Griesmayer, Erich (Unlisted, AT)
Two pCVD Diamond based Beam Loss Monitors (dBLM) are installed near the primary collimators of the LHC, with a dedicated, commercial readout-system used to acquire their signals. The system is simultaneously able to produce a high sampling rate waveform and provide a real-time beam loss histogram for all bunches in the machine. [...]

Radiation Levels at the LHC: 2012, 2015 and 2016 Proton Physics Operations in View of HL-LHC requirements / Martinella, Corinna (CERN) ; Brugger, Markus (CERN) ; Danzeca, Salvatore (CERN) ; Garcia Alia, Ruben (CERN) ; Kadi, Yacine (CERN) ; Stein, Oliver (CERN) ; Xu, Chen (CERN)
The variety of beam losses produced in the Large Hadron Collider (LHC) creates a mixed and complex radiation field. During 2012, 2015 and 2016, Beam Loss Monitors and RadMons were used to monitor the inte-grated dose and the High Energy Hadrons fluence in order to anticipate the electronics degradation and inves-tigate the cause of failures. [...]

Identification and Analysis of Prompt Dose Maxima in the Insertion Regions IR1 and IR5 of the Large Hadron Collider / Stein, Oliver (CERN) ; Brugger, Markus (CERN) ; Danzeca, Salvatore (CERN) ; Garcia Alia, Ruben (CERN) ; Kadi, Yacine (CERN) ; Kastriotou, Maria (CERN) ; Martinella, Corinna (CERN) ; Xu, Chen (CERN)
During the operation of the LHC the continuous particle losses create a radiation field in the LHC tunnel and the adjacent caverns. Exposed electronics and accelerator components show dose dependent accelerated aging effects and stochastic Single Event Effects which can lead to faults and downtime of the LHC. [...]

Data Analysis and System Survey Framework for the LHC Beam Loss Monitoring System / Xu, Chen (CERN) ; Dehning, Bernd (CERN) ; Zamantzas, Christos (CERN)
A data analysis framework has been developed to perform systematic queries and automatic analysis of the large amount of data produced by the LHC beam loss monitoring system. The framework is used to provide continuous system supervision and can give advance warning of any potential system failures. [...]
