Radiation hardness of structural materials at HL-LHC doses

Europe/Zurich
32/1-A24 (CERN)
Description
Within the Detector Technology group at CERN we have initiated a campaign aimed at identifying radiation hard materials for their use in HL-LHC experiment upgrades. This campaign is done as a follow-up of the CERN Yellow Reports, that have served as a reference to the wider detector community for several decades. Though still actual, these results require to be updated with newer materials and higher radiation doses, of interest for the detectors at the HL-LHC and to the next generation of HEP experiments.
The tested material categories include, non-exclusively, structural adhesives, thermal adhesives and composite materials. The irradiation is performed primarily with gamma photons from a Co-60 source, at different facilities. The sample typology and their testing are conceived to allow the qualification with one or more reference international standards.
In this seminar the specifics of radiation testing of materials will be addressed, the rationale behind the choice of the different test standards and the methodologies currently employed to define the characterization of irradiated materials. The most commonly used irradiation facilities will be described, with their specific advantages and drawbacks, the employed testing standards and the testing infrastructures. The seminar will offer as well an overview of good practices required in the selection and testing of materials for harsh radiation environments. Finally, the Maxrad database will be presented, developed for this campaign with the purpose of providing the HEP community with an intuitive way of accessing the produced test results.
Note that the seminar had to be moved again by 1 week!
