First Experience with the LHC Cryogenic Instrumentation / Vauthier, N ; Avramidou, R ; Balle, Ch ; Casas-Cubillos, J ; Ciechanowski, M ; Fernandez-Penacoba, G ; Fortescue-Beck, E ; Gomes, P ; Jeanmonod, N ; Lopez-Lorente, A et al.
The LHC under commissioning at CERN will be the world's largest superconducting accelerator and therefore makes extensive use of cryogenic instruments. These instruments are installed in the tunnel and therefore have to withstand the LHC environment that imposes radiation-tolerant design and construction. [...]

Influence of Thermal Cycling on Cryogenic Thermometers / Balle, C ; Casas-Cubillos, J ; Rieubland, Jean Michel ; Suraci, A ; Togny, F ; Vauthier, N
The stringent requirements on temperature control of the superconducting magnets for the Large Hadron Collider (LHC), impose that the cryogenic temperature sensors meet compelling demands such as long-term stability, radiation hardness, readout accuracy better than 5 mK at 1.8 K and compatibility with industrial control equipment.

Calibration of Cryogenic Thermometers for the LHC / Balle, Ch ; Casas-Cubillos, J ; Vauthier, N ; Thermeau, JP
6000 cryogenic temperature sensors of resistive type covering the range from room temperature down to 1.6 K are installed on the LHC machine. In order to meet the stringent requirements on temperature control of the superconducting magnets, each single sensor needs to be calibrated individually. [...]

Cryogenic Thermometer Calibration Facility at CERN / Balle, C ; Casas-Cubillos, J ; Thermeau, J P /CERN-CEA-IN2P3 LHC Construction Collaboration
A cryogenic thermometer calibration facility has been designed and is being commissioned in preparation for the very stringent requirements on the temperature control of the LHC superconducting magnets. The temperature is traceable in the 1.5 to 30 K range to standards maintained in a national metrological laboratory by using a set of Rhodium-Iron temperature sensors of metrological quality. [...]

Quality Assurance of LHC Cryogenic Instrumentation during Installation and Commissioning / Lopez Lorente, A (CERN) ; Balle, C (CERN) ; Casas-Cubillos, J (CERN) ; Fortescue, E (CERN) ; Gomes, P (CERN) ; Jeanmonod, N (CERN) ; Peñacoba, G (CERN) ; Vauthier, N (CERN)
The operation and monitoring of the LHC requires a cryogenic instrumentation system of an unprecedented size (800 instrumentation crates, holding 15000 sensors and actuators), with strict constraints on temperature measurement uncertainty and radiation hardness for all sensors and actuators. This paper presents the applied procedures of quality assurance and the specific hard- & software tools used to meet and track the mentioned requirements during its lifetime (fabrication, installation, commissioning, operation and maintenance); within the given constraints of time schedule, accessibility and coordination with other teams..

Validation of the Data Consolidation in Layout Database for the LHC Tunnel Cryogenics Controls Upgrade / Tovar-Gonzalez, A (CERN) ; Balle, C (CERN) ; Blanco, E (CERN) ; Fortescue-Beck, E (CERN) ; Fluder, C (CERN) ; Inglese, V (CERN) ; Pezzetti, M (CERN) ; Gomes, P (CERN) ; Wolak, T (CERN) ; Dudek, M (CERN) et al.
The control system of the Large Hadron Collider cryogenics manages over 34’000 instrumentation and actuator channels. The complete information on their characteristics and parameters can be extracted from a set of views on the Layout database, to generate the specifications of the control system; from these, the code to populate PLCs (Programmable Logic Controller) and SCADA (Supervisory Control & Data Acquisition) is automatically produced, within the UNICOS framework (Unified Industrial Control System).
