Test Beams Irradiation How to Apply Reimbursement
Under the AIDA-2020 TA programme, CERN provides access to 3 facilities
|
Test beams
- PS & SPS: The CERN PS (proton synchrotron) and SPS (super proton synchrotron) test beams provide particle beams in the energy range from 1 GeV to ~350 GeV. Upstream of the physicist’s test set-up sophisticated beam line equipment allows selection of the type, polarity and energy of particles as well as the beam intensity.

Irradiation
Access to two irradiation facilities at CERN is supported through the AIDA-2020 TA programme:
1) IRRAD (24 GeV/c protons): The irradiation facility is located in the EAST AREA of the CERN PS (Proton Synchrotron). It offers the possibility to expose materials to protons of 24 GeV/c. Objects with an area of up to 10 cm2 can be exposed to fluences of up to 1015 particles/cm2. Smaller objects can be irradiated up to higher fluences reaching up to 1017 particles/cm2 in irradiation experiments for which a beam spot of 5 mm2 FWHM is sufficient.
2) GIF++ (gamma source & H4 beam): The GIF++ facility is located in the H4 beam line of the CERN SPS North Area. It is combining a high energy charged particle beam (mainly muon beam with momentum up to 100 GeV/c, see H4 beam line characteristics below) with a 14 TBq 137Cesium source. The main purpose of this facility is to perform test beam experiments of gas detectors in an intense gamma background field. The 100 m2 GIF++ irradiation bunker has two independent irradiation zones making it possible to test real size detectors, of up to several m2, as well as a broad range of smaller prototype detectors and electronic components. The photon flux of each irradiation zone can be tuned using a set of lead filters with attenuation factors up to 50,000. More information about the facility can be found here

The minimum duration of access to the test beam area and irradiation facilities is 8 hours and can span to several weeks.
