  1. H4IRRAD TE/EPC Tests & Others? Aiming for first tests in February/March 2011

  2. Why H4Irrad • Testing of complex objects (big rack) with demanding supplies (high-power, water cooling,…) [e.g., power converters] • Testing of systems which require frequent access [e.g., EN/EL or future ‘patch-solutions’ for the LHC] • No fallback solution in case there is a problem with CNRAD • Long-term facility (i.e., PS-East-Area) is out of reach before 2013 (we still need it then) • High-energy ‘tail’ of particle energy spectra (e.g., tests for 60A power converters)

  3. Goal Of Today • Status of Generic FLUKA Calculations [Bart] • can we reach the required fluences • are the particle energy spectra comparable to the LHC • What is probably the best ‘shielding’ configuration • Test Requirements [Yves + …] • infrastructure • space/connections • Future Users other than TE/EPC [EN/EL?,…] • Test Conditions [Yves + ….] • Access requirements and turn-around in case of failures • Beam-time requirements • Next Steps: • Real Layout/Implementation of H4IRRAD [Illias, Bart] • Respective FLUKA calculations [Bart] • RP constraints and calculations [Chris] • Procedure to be followed? [Illias]

  4. TE/EPC Tests • LHC 4-6-8kA • 1 sub-converter (avec son électronique free wheeling diode) • LHC600A-10V • 1 rack de 2 convertisseurs • LHC120A-10V • 1 rack de 4 convertisseurs • LHC60A-08V • 4 convertisseurs placés en zone « + forte » (spectre)

  5. EN/MEF Required Details • Fluence Goal (to be discussed): • Inside: 1012cm-2 • Outside: 1011cm-2 • equipment to be tested (see tentative list from Yves before): • dimensions as specified through the links, or would you use special racks? • supply/services and connection requirements (is this available in the North-Area, H4 towards upstream end, could the power be taken from the magnet supplies,…) • possibility of lowering them with a crane into the test location (keeping in mind that the cables/pipes have to go along) • monitoring (of the power-converter) requirements during tests -> what installation is needed (cabling, space,…) • in case faults are observed, what measures will/can be taken for repair and what would be the procedure (keeping in mind that ideally one would look for multiple failures in order to analyse failure scenarios, as well as get a ‘guessed’ probability)
