  1. 133. High Power Target R&D needs for muon colliders
    Katsuya Yonehara (Fermilab)
    11/7/23, 3:30 PM
    Invited Oral

    The Muon Collider will serve as the discovery machine for various mysteries raised in the modern physics, while also facilitating collider experiments for the beyond standard model. The high power target system will be the central part of the collider. The performance of the system will determine the deliverable collider beam parameters, like a luminosity and collision energy. Therefore,...

  2. 117. Fabrication of Li-doped diamond by nuclear transmutation
    Dr Yasuto Miyake (RIKEN Nishina Center)
    11/7/23, 4:00 PM
    Contributed Oral

    Diamond is a wide bandgap semiconductor with excellent physical properties, such as breakdown voltage and thermal conductivity. It is expected to achieve performance beyond existing devices if it is applied as an electronic device. For this purpose, it is necessary to fabricate n-type semiconductors that can operate at room temperature, using lithium as a dopant. However, this has yet to be...

  3. 111. Thermal hydraulic characteristics studies of upward spiral flow windowless target (UST)
    Weifeng Yang (Institute of Modern Physics, Chinese Academy of Sciences)
    11/7/23, 4:15 PM
    Contributed Oral

    Accelerator driven subcritical system (ADS) is an attractive solution to nuclear wastes disposal. Spallation target is the key coupling component between accelerator and subcritical core in ADS, which plays very important role in adjusting the operation power of the overall system and maintaining security and stability. Liquid metal windowless spallation target is considered to have more...

  4. 103. Innovative material developments for target backings
    Kieran Kessaci (IPHC / Université de Strasbourg)
    11/7/23, 4:30 PM
    Contributed Oral

    A new generation of instruments dedicated to the study of superheavy elements has just been com- missioned in several laboratories around the world. One can cite the SPIRAL2 accelerator in GANIL, the SHE-Factory in FLNR and the new RILAC2 in RIKEN which are designed to reach beam intensities up to 10 pμA with heavy ions as 48Ca, 50Ti, 51V or 54Cr. Under these conditions, with more than 6.1013...

  5. 99. Development of Beam Target Cooling System Using Two-Phase Flow Natural Circulation
    Naoya Kamei (J-PARC/KEK)
    11/7/23, 4:45 PM
    Contributed Oral

    In recent years, beam power in particle accelerator facilities has been increasing to explore new physics. Accompanying this trend, the heat generation density of beam target is also increasing. Traditionally, pumped water cooling system have been used to cool high heat generation density beam targets. However, these systems require multiplexed pumps and equipment with high safety features....
