  2. GIF++ The new Gamma Irradiation Facility at CERN PhysicsDepartment Detector TechnologyGroup • Our 3 biddersoffered: • 137Cs source of 16,6TBq (450Ci) • A maximum source uncertainty of +/-20% • Encapsulation of the isotope whereheight≈ diameter(type R6060) • Vertical travel of the source carrier betweenSafe and Unsafe positions • Emergency return to SAFE position is possible by Gravityalone • Back to back front and rearcollimatorspositioned 1,5m above the floor • Parallelipipedic design of collimatorouter surfaces • Timercontrolledshutter for the (parasitic) rearcollimator • Fixation for a rearcollimation windowrestrictor • +/- 37° collimation angles everywhere • Fixation for both front and rearfield correction filters • Compliance to CERN Access Control, GIF Control System and 100m cables • Dismantling of BA102 immediatelyafterCommissioning(ADR7 isexpensive) • An optional 10 yearswarranty R. Fortin PH-DT-DD

  3. GIF++ The new Gamma Irradiation Facility at CERN PhysicsDepartment Detector TechnologyGroup • Remainingtechnicalsubtletiesthatneedbeagreedupon: • Twocompanies propose pneumatic actuation of the source carrier • One offers stepper motors • Twocompanies support their lead castle on a square stand • One offers a stool • Twocompaniesoffer a complete programmable attenuatorpackage • One does not • Twocompaniescommit to dismantlethe new GIF++ irradiatorafter 10 years • One will not • BUT ALL THREE BIDDERS OFFER ADEQUATE EQUIPMENT!
