/ Klyukhin, Vyacheslav (SINP, Moscow ; CERN) ; Ball, Austin (CERN) ; Berriaud, Christophe Paul (IRFU, Saclay) ; Curé, Benoit (CERN) ; Dudarev, Alexey (CERN) ; Gaddi, Andrea (CERN) ; Gerwig, Hubert (CERN) ; Hervé, Alain (Wisconsin U., Madison) ; Mentink, Matthias (CERN) ; Riegler, Werner (CERN) et al.
The conceptual design study of a Future Circular hadron-hadron Collider (FCC-hh) to be con-structed at CERN with a center-of-mass energy of the order of 100 TeV requires superconducting magnetic systems with a central magnetic flux density of an order of 4 T for the experimental detectors. The developed concept of the FCC-hh detector involves the use of an iron-free magnetic system consisting of three superconducting solenoids. [...]

This review article describes the performance of the magnetic field measuring and monitoring systems for the Compact Muon Solenoid (CMS) detector. To cross-check the magnetic flux distribution obtained with the CMS magnet model, four systems for measuring the magnetic flux density in the detector volume were used. [...]

A fiber optic sensors monitoring system for the central beam pipe of the CMS experiment

Res.) ; Beni, Noemi (CERN) ; Irace, Andrea (Naples U.) ; Gaddi, Andrea (CERN) ; Zeuner, Wolfram (CERN) ; Ball, Austin (CERN) ; Buontempo, Salvatore (CERN ; INFN, Naples) ; Breglio, Giovanni (CERN ; U. Naples (main) ; INFN, Naples)
In this paper we describe the main characteristics and experimental results, recorded in more than four years of data acquisition, of a temperature and strain monitoring system, called i-pipe, based on Fiber Bragg Grating (FBG) sensors arrays applied for the first time to a sector of the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN): the central beam pipe (BP) of the Compact Muon Solenoid (CMS). The monitoring system, consisting of four arrays of 16 FBG sensors each, as better described in the text, is placed on four directives of the LHC section that passes inside the CMS experiment, namely the CMS central BP.

Chapter 8: Collider-experiment interface

The HL-LHC targeted luminosities for the four main experiments will require upgrades of multiple subsystems in In particular, the LHCb experiment subsystems as the vertex locator (VELO), the ring-imaging Cherenkov (RICH) detectors and the tracking system will undergo a major upgrade in LS2, and its surrounding protection systems will be upgraded with neutral absorbers (TANB) to allow to reach the HL-LHC foreseen peak luminosity as from Run 3. Also, in LS2, ALICE will replace its beam-pipe for a new one, with smaller diameter and will also replace its tracking system, time projection chamber and will install a new fast interaction trigger detector.

The Large Hadron-Electron Collider at the HL-LHC
/ FCC-he Study Group Collaboration
The Large Hadron electron Collider, LHeC, is the means to move deep inelastic physics following HERA to the energy frontier of particle physics as it is being exploited by the HL-LHC. The paper presents a thorough update of the initial LHeC Conceptual Design Report (CDR) published in 2012. [...]
