3 EDMS No.: INTRODUCTION 1.1 CERN CERN, the European Organization for Nuclear Research, is an intergovernmental organization comprising Member States 1, with its seat in Geneva, Switzerland. Its facilities are located on either side of the border between Switzerland and France ( 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. At present, more than scientific users from research institutes all over the world are using CERN s installations for their experiments. The accelerator complex at CERN is a succession of machines with increasingly higher energies. Each machine injects the beam into the next one, which takes over to bring the beam to an even higher energy, and so on. The flagship of this complex is the Large Hadron Collider (LHC) as presented on the CERN website: Introduction to the Technology Department: Vacuum, Surfaces and Coatings Group The Technology (TE) Department is responsible for technologies, which are specific to existing particle accelerators, facilities and future projects. The main domains of activities cover: magnets (superconducting, normal conducting, fast pulsed magnets, electrostatic and magnetic septa), their machine integration and protection, power converters, cryogenics, high and ultra-high vacuum systems, coatings and surface treatments. The Vacuum, Surfaces and Coatings (VSC) Group is in charge of design, construction, operation, maintenance and upgrade of high and ultra-high vacuum systems for accelerators and detectors. It has expertise in domains as: Support on thin-walled vacuum chambers, windows and bellows compensation systems; Vacuum sealing and leak-tightness technology; Dynamic vacuum phenomena; Vacuum control systems, vacuum interlocks and monitoring tools; Surface treatments and chemical and surface analysis for accelerators and detectors; Coatings, electroplating and surface cleaning techniques; UHV characterization of material and surfaces; Degassing analysis and treatments; Management of the industrial support contract for vacuum work in accelerators. 1 except where stipulated otherwise, the term Member State(s) shall mean full member state(s) of CERN, associate member state(s) of CERN and associate member state(s) in the pre-stage of accession to membership of CERN.

4 2 EDMS No.: SCOPE OF THE SUPPLY CERN intends to place a five year blanket order contract for the supply of up to 25 Helium Leak Detectors for High Vacuum and Ultra High Vacuum applications (hereinafter referred to, in whole or in part, as the Supply ), as defined in this Technical Description and in accordance with the criteria defined in the Qualification Questionnaire. The Supply must include the following deliverables and activities: Design file; Technical documentation; Helium Leak Detectors with related accessories; Packing of the Supply; Shipping to CERN, if so requested; Training of CERN personnel on CERN site, if so requested; Preventive and corrective maintenance during the warranty period, including spare parts. 3. REQUIREMENTS 3.1 Technical Requirements The required supply consists of Helium Leak Detectors employing a method of detecting leakage with high sensitivity using a mass spectrometer. Two leak detection modes shall be possible: under vacuum and sniffing modes, using helium as tracer gas. The Supply must comply with the following parameters and conditions: Leak tightness of the Helium Leak Detector Pa.m 3.s -1 ; Detection of atomic mass 4 ( 4 He), and optionally atomic mass 2 (H2) and atomic mass 3 ( 3 He); Smallest detectable helium leak rate in under vacuum mode Pa.m 3.s -1 ; Smallest detectable helium leak rate in sniffing mode < Pa.m 3.s -1 ; Measurement range: 11 decades; Internal calibrated leak for calibration check; Helium pumping speed at the inlet greater than 1 L/s; Ion source with long life cathodes/filaments; Mass spectrometer with 180 magnetic sector field; Mobile; Screen indicator with adjustable sound level; Remote control device; Spare parts availability for a minimum of 10 years after the expiry of the initial warranty period of supply. 3.2 Production and testing facilities To guarantee the Ultra High Vacuum compatibility of Helium Leak Detectors, the strict application of UHV technology in fabrication, assembly and testing is required. The contractor shall be equipped with an on-site UHV cleaning facility.

5 EDMS No.: The contractor shall be equipped with an on-site ISO class 7 (according to ISO ) or better clean room which shall be used to assemble and test the all Helium Leak Detectors. 3.3 Norms and Standards The contractor shall use the ISO :2015 Cleanrooms and associated controlled environments -- Part 1: Classification of air cleanliness by particle concentration, or equivalent clean room standard, to quantify the class of clean room used and to maintain the clean room quality. The Supply shall comply with CERN safety rules (available at the link: and the Swiss, French and European legislation. 4. PERFORMANCE OF THE CONTRACT 4.1 Delivery Schedule The contract is scheduled to be awarded in December Further to notification of the award of contract, it is expected that the Helium Leak Detectors shall be delivered to CERN, from February 2019 onwards. CERN intends to place a five-year blanket order contract. CERN will issue release orders for the supply required based on the unit prices given in the contract. The estimated delivery quantity could be five Helium Leak Detectors per year, as shown below Quantities The quantity in the release order will be up to five Helium Leak Detectors. The delivery time from receipt of a release order shall not exceed eight weeks. 4.2 Working on the CERN Site In case of maintenance or training, the contractor shall work on the French part of the CERN site only. Particular features of the CERN site: Safety requirements including safety, occupational health, working conditions and environmental protection; Customs formalities since the installations straddle the Swiss-French border; 4.3 Acceptance Tests CERN intends to carry out receptions tests to prove the conformity of the supply with respect the technical requirements. These tests will be detailed in the forthcoming Invitation to Tender. Acceptance of the supply shall be given by CERN only after the delivered supply is deemed to be in conformity with the contract including documentation referred to in this technical description, all performance tests have been successfully completed and all tests or other certificates have been submitted to CERN.
