Procurement of the 10TBq 137Cs Source, Irradiator and Filters

1. GIF++ The new Gamma Irradiation Facility at CERN PhysicsDepartment Detector TechnologyGroup Procurement of the 10TBq 137Cs Source, Irradiator and Filters GIF 137Cs at start: 740 GBq Other characteristics of 137Cs remain: Half-life: 30.17 y Beta decay (gamma emission 662 keV) Inquiries carried out in 2009 suggest that the cost of the whole system will be around 300-400 K Given that cost > 200K, a market survey (1+ 2 weeks) followed by an invitation to tender (2 + 4 + 1 weeks) is necessary before contract is awarded.

2. GIF++ The new Gamma Irradiation Facility at CERN PhysicsDepartment Detector TechnologyGroup Criteriaedefined in 2009 • The source was described as: • Single 10 TBq137Cs source with it’s “Type B” travel container • << for transportation, fixation, use and service, in case the source will not supplied by the same firm than the radiator and/or on different timescales >> • The irradiator was described as: • One fully functional irradiator with it’s remote control console • << “Main” panoramic collimator, “Secondary” rear collimator, axis @ 150 cm above the ground, Dose Rate monitors to control the functionality, control room distance 30m… >> • The radiation filters were described as: • One filter system • << Remote controlled programmable, four vertical slides, attenuation ≥ 1:1 - 10,000:1 >> • Retrieval of the old irradiator… • This is an option of the specifications document R.

3. GIF++ The new Gamma Irradiation Facility at CERN PhysicsDepartment Detector TechnologyGroup Replies received in 2009 • - Three well-established firms (FR+CH+DE) showed interest to provide CERN with the future irradiator of GIF++ after the market survey of 2009. • - The three firms individually presented their project as a package where the Irradiator, Source and Controls were combined according to our specifications document SPSC-P-339. • These 3 candidates were asked to update and reiterate their proposals. • - Two bidders need to reengineer their project • - As soon as finalized, our updated specifications document will be sent to current and all potential candidates. • Today only one candidate fulfills our requirements!
