Motivation

The International Scoping Study (ISS) Machine Working Group will hold a workshop on ISS machine issues to discuss proton drivers, targetry, front-end systems, acceleration, and storage rings. A number of important issues have already been identified for each of these topics. The workshop will provide an opportunity to assess our progress in addressing these issues and for laying out a roadmap for future activities. We expect this workshop to be a true working meeting. Most of the day will be devoted to small group discussions, calculations, simulations and code development. The group will meet in late afternoon for progress reports and for general discussion. If possible, please bring a laptop to the workshop.

Workshop Goals

There are a number of areas where we hope we can make some progress during this workshop.

  • Proton Driver
    • Develop comparison table for different schemes.
    • Identify issues for producing short (~1 ns) bunches, e.g., define parameters for suitable bunch compression ring or transport line.
  • Targetry
    • Choice of proton beam energy for optimal pion production (and capture).
    • Assess minimum acceptable proton beam repetition rate at 4 MW intensity (solid and liquid targets.
    • Develop realistic solid-target scenario (rod, band, pellets, or granular).
    • Look at production rate as a function of proton bunch length in the range of 1–5 ns.
  • Front End
    • Begin simulating lowest energy KEK FFAG ring.
    • Study trade-off of cooling versus accelerator acceptance.
  • Acceleration
    • Look at FFAG longitudinal dynamics with non-zero transverse amplitude.
    • Begin simulating higher energy (1–3, 3–10, 10–20 GeV/c) KEK FFAG rings.
  • Storage Ring
    • Compare 20 GeV solution (upgradeable) and 50+20 GeV solutions.
    • Develop isosceles triangle ring with ~40° apex angle.
    • Begin tracking 50+20 GeV and isosceles triangle rings with errors.
