  1. 27. Radiation hardness requirements for organic materials in magnets and radiation environments in muon colliders, FCC, HL-LHC
    Francesco Cerutti (CERN)
    17/01/2025, 08:30
    Oral contribution

    An extensive experience has been gained throughout the last decades in the characterization of the radiation field impacting the magnets of existing and envisaged high-energy particle colliders. Detailed spatial distributions of the dose absorbed by the most exposed coils have been calculated by means of Monte Carlo simulation codes, through the description of the relevant radiation sources...

  2. 29. How can we increase the dose limits of organic insulation materials in superconducting accelerator magnets?
    Christian Scheuerlein (CERN)
    17/01/2025, 08:55
    Oral contribution

    In superconducting magnets of particle accelerators like HL-LHC, FCC-hh and a muon collider, shielding is required to reduce the dose absorbed by the magnet materials. A goal of the CERN Polymer Laboratory irradiation study is to increase the acceptable dose limit of the insulation systems beyond the limit of about 30-50 MGy that is presently assumed for shielding design.

  3. 22. Main results of the polymer irradiation studies for the ITER project at ATI Vienna
    Michael Eisterer
    17/01/2025, 09:20
    Oral contribution

    The talk summarizes the results of the combined neutron and gamma irradiation studies on polymers performed for the development of the insulation system of the ITER PF coils. The ultimate tensile stress (UTS) and the interlaminar shear strength of epoxy raisins and cyanate ester based polymers were determined as a function of the neutron fluence or dose rate. The fatigue behaviour of the UTS...

  4. 34. Dosimetry Techniques and Radiation Test Facilities for Radiation Damage Studies
    Federico Ravotti (CERN)
    17/01/2025, 09:45
    Oral contribution

    This contribution aims to review basic dosimetry principles, give examples for dose calculations as well as a brief overview of the available irradiation facilities for material irradiation studies and their associated dosimetric means. Their interest, limitations and some practical aspects involving the organization of irradiation campaigns for total ionizing dose testing will be also...

  5. 7. Cryogenic cooling options for radiation testing
    Dr Torsten Koettig (CERN)
    17/01/2025, 10:10
    Oral contribution

    Low temperature environments are vital for radiation testing of materials used in accelerator components. The cryogenic environment can either be established by immersion in a cryogenic fluid like Helium or in a dry manner by using cryocoolers as cooling source. The operation of helium cryostats requires frequent refill via long distance transfer lines. A direct cooling with cryocooler...
