  1. Possible Contribution to HE-LHC by KEK Current Activity And Future Effort

  2. Introduction • High Tc Superconductor (HTS) magnet R&D • important for future high energy and/or high intensity accelerator applications • Task Force Team at KEK (HTS-TF) • KEK cryogenics science center (CSC) • IPNS cryogenics group • Objective of HTS-TF • Promote HTS magnet R&D in KEK • Contribution to future high energy and/or high intensity accelerator applications such as HE-LHC

  3. KEK HTS-TF strategy High Energy Frontier: HE-LHC KEK/J-PARC Future Projects Other Applications Medical, ADSR etc HTS Magnet Technology High Intensity Frontier: Muon Projects

  4. Current Activity • High field dipole magnet R&D using A15 conductor for HL-LHC • Radiation Hard SC Magnet R&D for Muon Physics • JST project "Research and development of fundamental technologies for accelerator magnets using high Tc superconductors" • Study of strain effect on critical current of YBCO

  5. High field dipole magnet R&D using A15 conductor for HL-LHC • Fund • CERN-KEK fund. • Main objective • Nb3Al RHQT R&D • A15 Base Magnet Technology • Possible Spinout • Mechanical property of SC conductor • neutron or X-ray diffraction method • Radiation hard SC magnet technology • Radiation Hard glue R&D: Cyanate Ester etc • FTE and budget • FTE from KEK: ~3 • Annual budget: ~9 MJPY

  6. Radiation hard magnet R&D for muon physics • Fund • KEK internal • JSPS:Japan-US collaboration fund • JSPS: promotion program for young scientist B (M. Yoshida) • JST (travel budget) • Main Objective • Develop SC magnet system for high intensity muon beam production • Possible Spinout • Radiation hard SC magnet technology • Neutron Irradiation under cryogenic temperature • FTE and budget • FTE from KEK: ~1 • Annual budget: ~20 MJPY

  7. JST project"Research and development of fundamental technologies for accelerator magnets using high Tc superconductors" • Fund • Japan Science and Technology Agency (JST) under its Strategic Promotion of Innovative Research and Development Program • Main Objective & Possible Spinout • See Prof. Amemiya’s Talk • FTE and Budget for KEK • FTE from KEK ~0.5 • Budget for KEK 1 MJPY (for travel)

  8. Study of strain effect on critical current of YBCO • Fund • JSPS promotion program for young scientist B (M.Sugano) • Main Objective and Possible Spinout • Study of strain effect on critical current of YBCO • FTE and Budget • FTE: 0.3 • Annual Budget 1 MJPY (ends JFY 2011)

  9. Future Effort(Short Term) • Must be done with reasonable budget • Small share from current CERN-KEK fund • Other budget source? • Also within reasonable FTE • Less than 1 FTE overall • Direct Extension of Current Activity • Mechanical Study on HTS • Radiation hardness of HTS magnet • Design Study and Analysis

  10. Mechanical characteristic of HTS conductor • Stress vsJc measurement as well as internal strain measurement using neutron and/or x-ray beam. • FTE expected: 0.4 • Annual budget expected: 1~2 MJPY

  11. Radiation hardness R&D for HTS base magnets • Extending radiation hardness study to the issues specific to HTS base magnet technology. • FTE expected: 0.4 • Annual budget expected: 1~2 MJPY

  12. Conceptual design study of HTS base magnet for HE-LHC • Brief design study, performance analysis of HTS base magnet for HE-LHC. • Collaboration with Kyoto University as an extension of the program c) • No explicit FTE and Budget • Voluntary base

  13. Long Term Effort • HTS base model magnet for Accelerator • Aim • High Field: 20T • Time variant magnetic field & field quality • Collaboration • Kyoto University • FTE and Budget • FTE ~3 (needs KEK wide support) • Fund application: JSPS basic promotion S (for exmple) • Budget 200 MJPY total (for 5 years) • Competition is very keen • Or EU-Japan: need KEK-CERN support

  14. Summary • KEK CSC can contribute to HE-LHC • Indirectly for now • Small share from KEK-CERN fund • Can start some HTS related R&D at KEK • For long term effort • Need larger budget • We will apply to JSPS • but competition is very keen • Funds like EU-Japan is preferable • In any case we need, strong KEK/CERN supports
