1. GIF++ The new Gamma Irradiation Facility at CERN Physics Department Detector Technology Group 25/07/12 Project #4R. Fortin PH-DT-DI1 Status of procurement: 137 Cs source: Can we agree on the 16.65TBq? 60 Co source: If adopted, it should be sized for the planned bunker. Irradiator: ~50K€ needed to replace single isotope ~(5y). Maintenance cost proportionnal to complexity. Could a second single source irradiator be used for 60 Co? Attenuator: A multiple source irradiator is potentially bigger involving larger filters. Do 60 Co users really need the filtered panoramic collimator?
