  1. GIF++ Technical specifications Dorothea Pfeiffer GIF++ Users Meeting 29.06.2012

  2. Technical Specifications Facility • Radiation field • Irradiation source: 137Cs of 7 – 10 TBq, front and rear irradiation field (Talk by R. Fortin) • Particle beam: 100 GeV muons, 104 muons per spill in 10 x 10 cm2 • Area layout • Bunker (enough space for detectors 3 m wide and 4 m high) • Detector preparation area • Short term storage area • Control room/barracks • Control and logging system • Hard-wired common control system (source, beam, gas) • Web based monitoring and logging Source: http://cdsweb.cern.ch/record/1207380/files/SPSC-P-339.pdf Dorothea Pfeiffer

  5. Technical Specifications Infrastructure • Peripheral infrastructure and services • Electricity, Ethernet, compressed air, chilled water • Cable and pipe trays • Crane access • Gas supply, distribution and detection • Safety systems (beam, access, interlocks) • Infrastructure inside radiation area • Scanning system/shuttle (scan equipment across the beam) [to be discussed] • Temperature controlled environment (20° C, 30-50% humidity) • Trigger setup • Dose rate monitoring • Beam instrumentation • Neutral gases: Ar, N2, CO2, He, Xe at > 5 bar • Flammable gases: iC4H10, CH4, Ar/H2 • Special gases: C2H2F4, SF6, CF4 • Mixers, consumption monitors, analysis Source: http://cdsweb.cern.ch/record/1207380/files/SPSC-P-339.pdf Dorothea Pfeiffer

  6. GIF++ UseCase Dorothea Pfeiffer

  7. Infrastructure Issues • Access system: Single Person Access System (SAS) is required due to source activity • Temperature and humidity control of bunker: required values, admissible fluctuations, implementation (tent)? • Space for racks in bunker really needed? • Scanning device needed? How to implement it? • Others will come as we advance with the detailed design of the facility…. Dorothea Pfeiffer

  8. EN-MEF Team for GIF++ • Overall management/physicist in charge: I. Efthymiopoulos • Project Engineer during construction: D. Pfeiffer • Design and integration: S. Girod • Technical support area and infrastructure: M. Jeckel • 1st milestone: provide a functional specification for GIF++ and a final design reportby October 2012 • Combined effort with PH & User Feedback Dorothea Pfeiffer
