TUXGBD1 Potential and Issues for Future Accelerators and Ultimate Colliders 578
  • S.J. Brooks
    BNL, Upton, Long Island, New York, USA
  Particle colliders have been remarkably successful tools in particle and nuclear physics. What are the future trends and limitations of accelerators as they currently exist, and are there possible alternative approaches? What would the ultimate collider look like? This talk examines some challenges and possible solutions. Accelerating a single particle rather than a thermal distribution may allow exploration of more controlled interactions without background. Also, cost drivers are possibly the most important limiting factor for large accelerators in the foreseeable future so emerging technologies to reduce cost are highlighted.

THYGBD1 FCC: Colliders at the Energy Frontier 2908
  • M. Benedikt, F. Zimmermann
    CERN, Geneva, Switzerland
  The international Future Circular Collider study, launched in 2014, is finalizing a multi-volume conceptual design report. The FCC develops high-energy circular collider options based on a new 100 km tunnel. Long-term goal is a 100 TeV proton-proton collider (FCC-hh). The study also includes a high-luminosity electron-positron collider (FCC-ee), and it also examines lepton-hadron scenarios (FCC-he). Civil engineering and technical infrastructure studies were carried out. Global programs advance the development of high-field superconducting magnet technology based on Nb3Sn, the optimization of a suitable large superconducting RF system, and schemes for synchrotron radiation handling. In addition, the FCC study includes the design of the HE-LHC, housed in the LHC tunnel, and based on the same high-field magnet technology as the FCC-hh. The FCC study further includes an elaboration of the physics cases, including for heavy-ion collisions, and detector concepts, as well as staging and implementation scenarios. The FCC collaboration has grown to more than 120 institutes from 30 countries around the world. This invited talk summarizes the study achievements and the final designs.

Hidden Sectors: from Cosmos to Accelerators  
  • S. Gori
    UC, Cincinnati, Ohio, USA
  Cosmologists have determined that most of the matter in the universe is non luminous or "Dark". "Hidden sectors" refers to yet-unobserved quantum fields/particles that interact gravitationaly but not via the Standard Model gauge bosons. Some portion of the hidden sectors are candidates for dark matter. Speaker will make those connections, and then go on to a global survey low- and high-energy accelerator-based searches for hidden sector dark matter, both fixed-target and at colliders. Examples would include, but shall not be confined to, SPS and LHC (or HL-LHC), and beyond, etc.
