M-DSS: Description of the Service Requests

  • MM1. On the basis of drawings or sketches, machine or modify (assembly and adjust) components of mechanical sub-assemblies as part of equipment from accelerators or physics experiments, by using various types of Conventional fixed or portable machine-tools. Most frequently used raw materials are Stainless Steels (316LN and other grades), Copper and various alloys of Aluminium and glass fibre woven epoxy materials.
  • MM2. Or as described above, by using Non-Conventional machine-tools (milling, turning, CNC 3-axis, additive manufacturing, etc.). Used raw materials can be more specialized such as refractory metals (W/Nb/Ta).
  • MM3. Manufacture or modify, according to drawings or sketches, items belonging to the domains of fine metal work by use of various processes applied in thin sheet-metal work such as shearing, folding, rolling, drawing, spinning and unfolding.
  • MM4. Manufacture or modify, according to drawings or sketches, items by using techniques belonging to the domains of high-quality welding and joining using various welding processes such as ARC, MIG, TIG and Plasma, as well as brazing and soldering. The welder must be in possession of at least 2 qualifications according to EN-ISO 9606-1 to obtain CERN’s accreditation.
  • MM5. Work-shop supervision, follow-up of the machine-tool maintenance, conformity checks and requirements for specific tooling.
  • MM6. On the basis of drawings or sketches, programming of non-conventional machine-tools (milling, turning, CNC, additive manufacturing, etc.), for components of mechanical sub-assemblies linked to MM2 service requests.
  • MC1. Assembly, maintenance, or decommissioning of mechanical equipment and ancillaries for accelerator technical systems, often requiring Ultra High Vacuum (UHV) expertise.
    • Typical systems can be, but are not limited to, beam instrumentation, beam intercepting devices and radiofrequency equipment.
    • Decommissioning can consist of destructive removal including sorting and packaging for recycling of waste or operational recuperation and storage of the equipment.
  • MC2. Assembly of mechanical equipment and ancillaries for accelerator technical systems, requiring ISO 6 to 8 cleanrooms experience or accreditations and expertise in assembly of Ultra High Vacuum (UHV) equipment.
    • Typical systems can be, but are not limited to, High Voltage (HV) beam deflectors, beam intercepting devices, radiofrequency fundamental (FPC) and higher order mode (HOM) power couplers, and other UHV and HV related accelerator beam line equipment.
  • MC3. Assembly, or maintenance, electrical cabling, or decabling and decommissioning, of electro/mechanical equipment, hydraulic circuits, and ancillaries for accelerator technical systems, requiring the minimum electrical accreditations of B1V, BR H1V. For some of the tasks the electrical accreditations of, B2V H2V, shall be required.
    • Typical systems can be, but are not limited to, power converters, High-Voltage transformers, power compensators in (partial outside) HV areas, amplifiers for radiofrequency equipment and pulse forming networks with dedicated switches.
    • Decommissioning can consist of destructive removal including sorting and packaging for recycling of waste or operational recuperation and storage of the equipment.
  • MC4. Assembly of mechanical equipment and ancillaries for accelerator technical systems, requiring ISO 3 to 4 cleanrooms experience or accreditations and expertise in assembly of Ultra High Vacuum (UHV) equipment.
    • Typical systems can be, but are not limited to, superconducting radiofrequency (SRF) cryomodules and other UHV and HV related accelerator beam line equipment.
  • MO1. Reception of components, verification of conformity and update of the inventory with keeping of accurate records of stock, using the enterprise asset management (EAM) solutions in place. Process orders and organise the dispatch and delivery of material and components. Controlling and monitoring the safe storage and movement of all inventory items and ensures that they are available when required.
  • MO2. Preparation and maintenance of test benches and instrumentation for accelerator technical systems.
  • MO3. Follow up of vacuum related activities, such as closing of vacuum vessels, pump down, bake out preparation and leak detection.
  • MO4. Production Management; Monitoring of electromechanical equipment production,Maintaining accurate production records, Updating as-built mechanical drawings and electrical schematics, Coordinating on-site installation as well as S264/SY personnel.
