  1. The Next Generation of aGamma Irradiation FacilityGIF++ presented to SBA

  2. Contents • Users’ requirements • Layout • Adaptation to minimize impact on H2 (extension) • Wall and roof shielding, raised floor Dennis • Irradiator: filter system Dennis • Radiation field Dorothea • Users’ installation of permanent trackers Dorothea • Technical infrastructure • Schedule, budget A. Fabich

  3. Users’ requirements Document “Users’ requirements” under approval • Re-establish former GIF functionality • Secondary muon beam intercepting a photon field • Space for installing detectors to be tested • max. MDT (few meter) and calorimeters(few tons) • Common infrastructure and several gases A. Fabich

  4. Temperature/humidity • Users’ requirements: 20-24 °C, humidity 30-50%. • Optional: small ventilation unit (if really required) • Not required for safety aspects Measurements: autumn 2012 – spring 2013 (courtesy: R. Guida) A. Fabich

  5. Irradiator • Photons 662 keV (Cs-137 source, 16 TBq) • Prompt radiation only, no activation • Tender completed, order placed these days Irradiator directphotonfields 9 m 4.80m 6 m A. Fabich

  6. H4 – PPE 154 Maintain possibility for H2 extension Maintain minimum 2m wide corridor (central) A. Fabich

  7. GIF++ implementation Bunker Gas zone Counting rooms Preparation zone Central corridor A. Fabich

  8. Technical systems • Electricity, light (+emergency), Ethernet, cabling, cable trays, demineralised water, NO cryogenics • Beam equipment • Gases • Neutral and mixtures (containing flammable gases) • 15 gas supplies from the gas hut (build. 909) • 10 patch panels in bunker/preparation zone • Each for 4 neutral and 4 hazardous gases Supply lines should mainly be installed in raised floor A. Fabich

  9. Safety responsibility with SBA (together with CERN expert groups) • Radiation shielding • Flammable gas detection and ODH (in bunker) • Fire detection • Access system/personnel protection • Interlock(s), also with irradiator • Gas zone: ATEX conform (PH) A. Fabich

  10. Access: PPE, PPG, PPX and MAD PPX • Roof access for large equipment (using the bridge crane) • PPX/PPE: standard • PPG: concrete, motorized • MAD • Material access device for small equipment of computer size PPG MAD PPE • PPE+turnstile • single person entrance at a time without need for patrol A. Fabich

  11. PH responsibilities • Defining users’ requirements • Irradiator procurement • Equipment in the gas (mixing) zone • analysers, mixers … + ATEX conformity • Construction of permanent m-detectors • Slow control of irradiator, gas equipment, logging • DAQ system A. Fabich

  12. Cost estimate • Material+FSU • To be reviewed within functional design • Excluding PH contributions A. Fabich

  13. Schedule FINISHED: Tender documents ready ONGOING: Bunker design (false floor, roof, cable trays) about to be finished ONGOING: First draft ready to be circulated STARTED: Discussions with users about DAQ 13/02/2013 D. Pfeiffer (EN-MEF-LE) – 17/10/2012 A. Fabich

  14. Outlook • Until summer 2013 • Functional design to be completed • Operation scheme(s) (beam, irradiator access) • From summer 2013 • Area cleaning • Installation • Completed by summer 2014 A. Fabich
