      • The scope of this collaboration is the contribution to the optimization of the initial layout of the FCC-hh collimation system (e.g. input to choice of collimator gaps, optics, impedance, collimator design and material choices, number of collimation insertions, etc.) as well as the contribution to the Machine Detector Interface studies.
    • Addendum signed on 13 February 2017

The knowledge will be transferred to the FCC study in order to serve as input to develop a baseline concept for a future collider

    • Memorandum of Understanding signed on 03 September 2014
    • Addendum signed on 25 August 2014
      • The scope of this collaboration is to perform impedance calculations of the key hardware components of the machine (in particular beam screen and collimation system) and to study instability thresholds and other single‐beam collective effects for FCC‐hh.
    • Addendum signed on 29 May 2017
      • The scope of this project is to perform studies related to "UFOs" (dust particles entering into the circulating beam) at the LHC with the goal to devise a parameterisable model that permits estimates of the effect occurrence and impacts at particle accelerators with significantly higher energy and intensity. The institute will also contribute to the study of mechanisms of the origin of such particles, investigating the presence and the parameters of dust particles in the LHC vacuum equipment, and to study what mechanisms can detach particles from the wall. Ultimately, it will provide consultancy for reliability and availability related matters for FCC-hh and FCC-ee including the respective injector chains and technical infrastructures.

    • Addendum signed on 30 October 2014
      • The scope of this collaboration is to study advanced refrigeration systems for the hadron collider (FCC-hh) with a focus on cooling of beam screens, thermal shields and current leads, refrigeration cycle, efficiency and investment cost, specific hardware (e.g. turbo-compressors, motors, turbo-expanders, heat-exchangers, circulators) requirements and characteristics, proposals of a reference and alternative cycle as well as recommendations and inventory of specific developments.
    • Addendum signed on 24 October 2016
      • The scope of this collaboration is to study advanced refrigeration systems based on a neon-helium (Nelium) turbo-brayton cycle for the cooling of beam screens, thermal shields and current leads of the hadron collider (FCC-hh).

    • Addendum signed on 28 March 2018
      • This R&D project is carried out in the scope of the EASITRAIN H2O2O EU project. The scope of this collaboration is to develop, construct and operate a turbocompressor test stand for the R&D of a novel Helium-Neon-based refrigeration cycle. The scope of work is to evaluate performance, operating range and optimization potential of high-speed centrifugal compressors for different mixtures of helium and neon, including off-design conditions in terms of mixture composition. The Technical University Dresden (TUDRESDEN), also beneficiary in the EASITRIAN project cooperates with USTUTT on the design and the operation of the test stand. TUDRESDEN will use the acquired test data and operational experience for research purposes on a Nelium-based cryogenic refrigeration cycles in the scope of the FCC study and the EASITRAIN H2020 project.
