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 EN-STI Group The Engineering Department (EN) 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. Within the Engineering Department, the Sources, Targets and Interactions (STI) Group is in charge of the Beam Intercepting Devices (BID). 1.3 Introduction to the R2E Project The R2E (Radiation to Electronics) Project is in charge of ensuring the proper performance of the accelerator complex (LHC accelerator and its injector chain) with respect to radiation effects on its equipment. This is achieved by combining mitigation (such as shielding or relocation) and prevention (such as radiation tolerant system design and qualification) activities on such equipment. With the expected increase of radiation levels in the accelerator complex, the R2E studies and actions are expanded to radiation damage on other equipment than electronic ones. 2. SCOPE OF THE SUPPLY CERN intends to place a blanket purchase contract for the performance of irradiation testing of CERN samples (hereinafter referred to, in whole or in part, as the Supply ), in order to assess their lifetime in specific areas of the accelerator complex, as defined in this Technical Description and in accordance with the criteria defined in the Qualification Questionnaire. CERN expects to place around 25 release orders following irradiation requests each year, without any commitment on CERN side that this quantity will be actually reached. 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: Deliverables and Activities Included in the Supply For each release order (see 4) shall be supplied: Irradiation of the samples provided by CERN (see 3.1.1) according to the descriptions stated in 3. The related irradiation technical requirements will be specified in the release order (see 4); Samples handling, preparation and shipment, as described in 3; Characterisation tests and associated raw data, if applicable, as described in 3.1.3; Technical documentation, including the irradiation report, as described in Items Made Available by CERN CERN will provide the samples to be irradiated (as described in 3.1.1). 3. REQUIREMENTS 3.1 Technical Requirements Samples to be Irradiated By samples it shall be understood: raw materials of different kinds (such as but not limited to polymers, liquids, lubricants); components and devices (such as but not limited to electronics, optical components, actuators); and also full equipment (such as but not limited to pumps, loudspeakers or sprinkler heads). The dimensions of one sample will range from a few mm 3 up to 1 m 3, and its weight will range from a few grams up to 500 kg Irradiation Conditions The irradiation requests will be of three different types: Total Ionizing Dose tests (TID), Displacement Damage tests (DD) or Single Event Effect tests (SEE). All irradiations shall be performed according to applicable norms and standards, as described in 3.2, and the dosimetry for each sample shall be provided to CERN and shall be stated in the irradiation reports (see 3.3). Combination of several similar irradiation requests shall be possible (typically, requests with similar irradiation condition, performed within the same facility) in a single irradiation in view of optimizing the beam time Total Ionizing Dose Tests TID tests shall be performed with Gamma photons from 60 Co sources. The reachable dose rates shall range from 1 Gy[air]/h up to at least 30 kgy[air]/h. Gamma irradiation shall be performed in static position, or in dynamic mode by means of a conveyor system. The total volume for samples to be irradiated simultaneously (combination of irradiation requests) will not exceed the volume of a EUR-EPAL pallet (80 cm 120 cm 190 cm height), and the total weight will not exceed 500 kg. For such volumes, dose rates of at least 8 kgy[air]/h shall be reachable.

5 EDMS No.: For best dose homogeneity within the irradiated samples, the samples may be flipped over at halfway of the irradiation process Displacement Damage Tests DD tests shall be performed with accelerated hadrons: Neutrons with flux of at least n/cm 2 /h, and energy of at least 2.5 MeV; Protons with flux of at least p/cm 2 /h, and energy of at least 30 MeV Single Event Effect Tests SEE tests shall be performed with accelerated hadrons: Neutrons with flux of at least n/cm 2 /h, and energy of at least 14 MeV; Protons with flux of at least p/cm 2 /h, and energy of at least 150 MeV Environmental Conditions If CERN requires an irradiation under a specific atmosphere, the samples shall be conditioned accordingly for the duration of the irradiation: Irradiation in open containers, with holes allowing for the flow of air around the samples. The irradiation facilities shall allow for a regular air renewal in the irradiation room; Irradiation in non-hermetic closed containers filled with air, allowing for ozone accumulation; Irradiation in hermetic container with vacuum or filled with a specific gas (the hermetic container shall be equipped with a valve allowing for eventual overpressure release). In the case of active tests (see 3.1.3), testing environment temperature shall be controlled during the samples irradiation, down to 10 K and up to 400 K Characterisation Tests Pictures of each sample shall be routinely taken pre- and post- irradiations. If characterisation tests are requested, such characterisation tests shall be performed pre- and post- irradiation (then referred to as "passive tests") or in-situ (characterisation performed during the irradiation, with wired samples, then referred to as "active tests"). The characterisation tests will be electrical tests, electronic tests (which shall be done under electrostatic discharge protected area if applicable), optical tests, mechanical tests, or any other type requested by CERN. In the case of specific test setups, CERN will provide the test bench and specifically train a technical employee who shall monitor and record the test data. The raw data from the characterisation tests shall be provided to CERN as part of the supply. 3.2 Norms and Standards The Supply shall comply with the following norms and standards: IEC 60544: Determination of the effects of ionizing radiation on electrical insulating materials; IEC : Radiation interaction and dosimetry; IEC : Procedures for irradiation and test; ISO : Sterilization of health care products Radiation Guidance on dosimetric aspects; Electronic irradiation tests:

Additional pictures may be added, as required for clarity of the irradiation report; Characterisation tests results, if applicable, as described in 3.1.3; Any other relevant information. 4. PERFORMANCE OF THE CONTRACT CERN will place a blanket purchase contract for the Supply. The Supply will be ordered via release orders based on provided offers. The offers shall be prepared from CERN irradiation requests that will describe the number and type of samples to be irradiated, the irradiation conditions requested for each sample or group of samples, and the characterisation tests if applicable. The unit prices defined in the contract shall be used in order to prepare the offers. 4.1 Delivery Schedule The detailed schedule will be displayed in the release orders, as agreed within the irradiation plan. The following indicative schedule shall be respected:
