2 Radiation Sensors for GIF++ (Project) GIF++ Location: SPS North Area, H4 Beam Line The intensity of the source will be about 10 TBq providing up to 2 Gy/h at a distance of 50 cm. The ~10 times higher outcoming uniform photon flux than in the previous GIF corresponds to the expected step in intensity while moving to sLHC conditions. The Cesium source of GIF++ should provide uniform gamma irradiation on a vertical surface of 7,5 m wide by 4 m high at a distance of 5m through the front of the irradiator. A secondary collimator located in the opposite direction should provide a spherically noncorrected spot of 2,6 m at a distance of 7 m. Ceiling clearance will be 4 m everywhere inside the bunker. A second irradiation beam will be available at 180 degrees to the main photon beam axis. This area shall be defined by a separate collimator that allows irradiation of detectors with a higher flux but over a smaller area. It shall be possible to activate or isolate the second irradiation beam using a separate shutter. Plamen Iaydjiev INRNE, Sofia AIDA WP meeting CERN June.2012
