  1. (brief) Update on the target facility M. Calviani, on behalf of the CENF SBWG team CENF PTM meeting – 5th February 2014

  2. Updates on integration work Mass 35t • Upgrades on the support module design • Detail about the air tightness • A new designer (V. Clerc) will start working in the overall integration S. Girod

  3. Outstanding items • Target cost very high due to reduced horn inner conductor (IC) diameter (24 mm Ø) • Future mechanical studies will assume the possibility of a 30 mm IC Ø(MiniBooNE) • Preliminary neutrino studies have been performed for this config. 24 + 12 mm Ø 30 + 12 mm Ø

  4. Complete extraction system CV M. Battistin, M. Archambault

  5. Cooling circuits in the cooling room Horn & Reflector Cooling: 17-22 °C Shield + 2xHelium cooling: 27-> °C M. Battistin, M. Archambault

  6. CV further feedbacks • Hydraulic circuits under completion • AL capable of executing a conceptual design of a purification system for the CENF helium vessel • He purity in the order of 1% can be reached with a single membrane circuit • He purity in the order of 0.1% can be reached with a double cascade membrane circuit (PRESENT REFERENCE) • He purity in the order of the ppm (or more) requires active carbons, silica gel and cryogenic trap technology. M. Battistin

  7. V. Venturi

  8. V. Venturi

  9. V. Venturi

  10. Radioprotection aspects C. Strabel • Input for dump design (waste zoning) • Air contamination for the He vessel (1%, 0.1% and ppm)

  11. Dump (1st and 2nd) installation • 2 solutions proposed by EN/HE • “open trench” solution • Installation with blocks on baskets • After an ensuing discussions a hybrid solution with the first dump installed via a vertical shaft will be further investigated R. Rinaldesi, C. Bertone

  12. Thanks
