To further improve the performance and reliability of the quench detection system (QDS) for main quadrupole magnets in the Large Hadron Collider (LHC), there is a planned upgrade of the system during the long shutdown period of the LHC in 2019-2020. While improving the already existing functionalities of quench detection for quadrupole magnets and field-bus data acquisition, the enhanced QDS will incorporate new functionalities to strengthen and improve the system operation and maintenance.

Analysis of the Dependability of the LHC Quench Detection System During LHC Run 2 and Further System Evolution
/ Podzorny, Tomasz (CERN) ; Calcoen, Daniel (CERN) ; Denz, Reiner (CERN) ; Siemko, Andrzej (CERN) ; Spasic, Jelena (CERN) ; Steckert, Jens (CERN)
The quench detection system (QDS) of the LHC superconducting circuits is an essential part of the LHC machine protection and ensures the integrity of key elements of the accelerator. The large amount of hardwired and software interlock channels of the QDS requires a very high system dependability in order to reduce the risk of affecting the successful operation of the LHC. [...]

Development of a Digital Quench Detection System for Nb$_3$Sn Magnets and First Measurements on Prototype Magnets
/ Steckert, Josef (CERN) ; Kopal, Josef (CERN) ; Bajas, Hugues (CERN) ; Denz, Reiner (CERN) ; Georgakakis, Spyridon (CERN) ; De Matteis, Ernesto (CERN) ; Spasic, Jelena (CERN) ; Siemko, Andrzej (CERN)
The High Luminosity upgrade for the Large Hadron Collider LHC (HL-LHC) requires new Nb$_3$Sn superconducting magnets and it triggers a development of novel hardware for the quench detection system (QDS) based on a field programmable gate array (FPGA) digital platform and a number of individually isolated analogue front-ends. Galvanic insulation has been implemented downstream the analogue to digital convertors to eliminate a usage of analogue isolation amplifiers. [...]

The High Luminosity Upgrade of the LHC [1] will incorporate a new generation of superconducting elements such as high field superconducting magnets based on Nb$_3$Sn conductors and MgB$_2$ high temperature superconducting links for magnet powering. The proper protection and diagnostics of those elements require the development of a new generation of integrated quench detection and data acquisition systems as well as novel methods for quench detection.

Prior to the re-start of the Large Hadron Collider LHC in 2009 the protection system for superconducting magnets and bus-bars QPS will be substantially upgraded. The foreseen modifications will enhance the capability of the system in detecting problems related to the electrical interconnections between superconducting magnets as well as the detection of so-called aperture symmetric quenches in the LHC main magnets..
