Training in Vacuum Technology for JUAS 2013 Students Paolo Chiggiato Technology Department Vacuum Surfaces and Coatings Group CERN, CH-1211 Geneva Overview of the VSC group competences Outgassing measurement and material assessment (B. 101-1) Instrumentation: total pressure and gas analysis (B. 30-1) LHC vacuum system and NEG pumps (B. 113-R) Monitoring and control systems of the world longest beam circuit (B. 30-1) JUAS Practical Day -- Vacuum Technology – Paolo Chiggiato

  2. The Circuit in the CERN’s Meyrin Site B. 30 and 113 B. 101 1 Km from B. 30 to B. 101 JUAS Practical Day -- Vacuum Technology – Paolo Chiggiato

  3. Overview of the VSC group competences In all places of the CERN accelerator complex there is only one common thing: vacuum 128 Km long vacuum system: the longest in the world. All vacuum degrees and all vacuum technologies are employed at CERN JUAS Practical Day -- Vacuum Technology – Paolo Chiggiato

  4. Overview of the VSC group competences • 2850ion pumps, 450turbomolecular pumps, 325Ti sublimation pumps,… • 6 Km of NEG coated beam pipes, 2750pressure gauges, 40 leak detectors and 100 RGAs,1930roughing valves and 510 gate sector valves And the numbers are continuously increasing… JUAS Practical Day -- Vacuum Technology – Paolo Chiggiato
