Alessandro Saputi EN/CV/PJ Introduction to CERN CERN, the European Organization for Nuclear Research, is an intergovernmental organization with 20 Member States. CERN’s mission is to enable international collaboration in the field of high-energy particle physics research and to this end it designs, builds and operates particle accelerators and the associated experimental areas.

Alessandro Saputi EN/CV/PJ The Engineering Department provides CERN with the Engineering Competences, Infrastructure Systems and Technical Coordination required for the design, installation, operation, maintenance and dismantling phases of the CERN accelerator complex and its experimental facilities. Introduction to CERN and EN-CV group EN-CV Group Cooling & Ventilation The mandate of the CV group concerns the consolidation, operation and maintenance of the cooling systems, pumping stations, air conditioning installations and fluid distribution systems for the PS, SPS and LHC, The CV group is in charge of consolidation and projects from market survey to commissioning stages. The CV group also has the responsibility of the LHC Experiments specific cooling equipment and the development of future prototypes and their production.

Alessandro Saputi EN/CV/PJ The NA62 experiment is a new particle physics experiment in preparation in the North Area of the SPS accelerator at CERN. It aims to start physics with data taking in It will become the first experiment in the world to probe the decays of the charged kaon with probabilities down to 10 −12. The experiment is focused on precision testing of the Standard Model by studies of rare decays of charged kaons. Introduction to the Na62 Experiment

Alessandro Saputi EN/CV/PJ The Gigatracker is a spectrometer that provides precise measurements of momentum, time and angle of the incoming 75 GeV/c kaon beam. The Gigatracker will be placed in a vacuum, in order to minimize the interaction of beam particles with air. It shall be operated at a temperature of -25 degree Celsius to reduce radiation-induced performance degradation. Introduction to the Na62 Gigatracker

Alessandro Saputi EN/CV/PJ Scope of the supply Design, manufacture, assembly, installation, testing and commissioning at CERN of a cooling system for the NA62 GTK.

Alessandro Saputi EN/CV/PJ Scope of the supply

Alessandro Saputi EN/CV/PJ Each Gigatracker will be equipped with one heat exchanger (“micro-channel cooling device”), since heat produced during operation of the detectors has to be removed. The cooling system will supply the MCDs with liquid perfluorocarbon C6F14 at the following conditions: The Cooling System (requirements) Fluid C 6 F 14 Number of circuits 3 Cooling power for each MCDQ GTK from 34 W to 100 W Operating temperature MCD inlet)TiTi from - 30  C to +20  C Maximum allowable temperature during operationsT amb +20  C Supply temperature precision ±1K Supply temperature stability ±0.5K Maximum allowable pressure PS of the equipment in conformity with the European directive PED 97/23/EC pipi from 13 bar to 16 bar Pressure drop on MCDΔpfrom 6 bar to 8 bar Flow rate MCD inlet)GiGi from 7 g/s to 9 g/s Mass flow rate (secondary pipelines - for each circuit)GrGr 100 g/s

Alessandro Saputi EN/CV/PJ Cooling System Layout All components shall be installed on one compact skid (maximum 3 m x 3 m x 3 m) with the exception of: Pre-heat exchangers YHX YHX YHX6103, temperature transmitters TT6101 – TT TT6109 and the MCDs. These components shall be installed in the TCC8 gallery close to the GTK detectors. PLCs shall be installed in a cabinet located in the building 918 – room 008 (~ 120 m from the cooling station - see figure 5). The maximum dimensions of the cabinet shall be 60 cm x 210 cm x 80 cm (width x height x length).

Alessandro Saputi EN/CV/PJ Cooling System Layout All Electro-pneumatic valves, electrical and control components (including all necessary hardware, I/O cards) shall be installed in a cabinet fixed upon the skid.

Alessandro Saputi EN/CV/PJ Items and Services Supplied by CERN The CERN will provide: Power cables from the CERN main electrical distribution cabinet to the cooling system; Compressed air supply; Cables from main electrical & control cabinet to the PLC’s cabinet; Control software (with the information provided by the contractor - see also §3.7.2); Monitoring system; Ethernet link, the connection socket and the address parameters; MCD heat exchangers and their final connection to the cooling system; The fluid for the first filling of the plant. CERN will install the pre-heat exchangers YHX YHX YHX6103 designed and provided by the contractor. CERN will perform the test of the dialogue of all instruments through the CERN Ethernet network with the SCADA supervision.

Alessandro Saputi EN/CV/PJ Control and communication system & Interlocks Four (4) inlets and four (4) outlets interlocks shall be available to be hardwired connected to the Detector Safety System (DSS). These shall allow the possibility to stop the cooling on each cooling loop separately or to stop the whole cooling system on DSS request. The control and communication system shall be of PVSS-UNICOSS type. A local touch panel will allow the local control/supervision of the system. Remote PVSS-UNICOS supervision shall be available on technical network. NA62-GTK operator shall have remote access to the control of the following operating parameters: GTK inlet temperatures for each GTK loop; GTK flow rates for each GTK loop.
