The Cryogenic System for the LHC Test String 2 : Design, Commissioning and Operation / Blanco-Viñuela, E ; Calzas, A ; Casas-Cubillos, J ; Chanat, D ; Gomes, P ; Knoops, S ; Sanmartí, M ; Serio, L ; Suraci, A
A 107-m long superconducting magnet string representing a full-cell of the LHC machine was designed for assembly and commissioning at CERN in order to validate the final design choices. This new facility, thereafter called Test String 2, and its cryogenic infrastructure cons ist of feed and return boxes coupled via transfer lines to a 6 kW @ 4.5 K refrigerator and to a low pressure pumping group, a separate cryogenic distribution line, an electrical feed box with HTS current leads, 2 quadrupole and 6 dipole prototype and pre-series superconducting magnets..

The Control System for the Cryogenics in the LHC Tunnel / Gomes, P (CERN) ; Anastasopoulos, K (Natl. Tech. U., Athens) ; Antoniotti, F (CERN) ; Avramidou, R (Natl. Tech. U., Athens) ; Balle, Ch (CERN) ; Blanco-Viñuela, E (CERN) ; Carminati, Ch (CERN) ; Casas-Cubillos, J (CERN) ; Ciechanowski, M (AGH-UST, Cracow) ; Dragoneas, A (Natl. Tech. U., Athens) et al.
The Large Hadron Collider makes extensive use of superconductors, in magnets for bending and focusing the particles, and in RF cavities for accelerating them, which are operated at 1.9 K and 4.5 K. The process automation for the cryogenic distribution around the accelerator circumference is based on 16 Programmable Logic Controllers, each running 250 control loops, 500 alarms and interlocks, and a phase sequencer.

First Assessment of Reliability Data for the LHC Accelerator and Detector Cryogenic System Components / Perinic, G (CERN) ; Claudet, S (CERN) ; Alonso-Canella, I (CERN) ; Balle, C (CERN) ; Barth, K (CERN) ; Bel, J F (CERN) ; Benda, V (CERN) ; Bremer, J (CERN) ; Brodzinski, K (CERN) ; Casas-Cubillos, J (CERN) et al.
The Large Hadron Collider (LHC) cryogenic system comprises eight independent refrigeration and distribution systems that supply the eight 3.3 km long accelerator sectors with cryogenic refrigeration power as well as four refrigeration systems for the needs of the detectors ATLAS and CMS. In order to ensure the highest possible reliability of the installations, it is important to apply a reliability centred approach for the maintenance. [...]

The Applicability of Ultrasonic Oxygen Deficiency Hazard Detectors in the LHC Accelerator Tunnel / Brodzinski, R L ; Chorowski, M ; Gizicki, W ; Ostropolski, W ; Riddone, G
The Large Hadron Collider (LHC), will contain about 96 tonnes of high-density helium, mostly located in the underground components of the LHC machine. Some of potential LHC cryogenic system failures might be followed by helium discharge to the tunnel and potential decrease of the oxygen concentration below the safety level of 18% cannot be excluded.

Flow and Thermo-mechanical Analysis of the LHC Sector Helium Relief System / Chorowski, M ; Fydrych, J ; Riddone, G
A simultaneous resistive transition of a LHC magnet sector, which may occasionally occur, will cause rapid helium outflow from magnet cryostats to a special relief system composed of long pipes, buffer volumes and accessories. The paper presents some safety and operational aspects of this system. [...]
