Preparation of pre-CDR for LhARA

Last updated: 20Nov19 [AK]

An effort to develop a 'pre-CDR' has been initiated supported by the award of an STFC Opportunities 2019 award. This page is being used to collect and share information in the preparation of the pre-CDR.

Key dates

• 29 Nov 2019: First issue of the baseline. This will include lists from the various systems of what needs to be updated on the existing floor layout, WBS, interfaces document and the parameter table.
• 31 Dec 2019: First end-to-end tracking simulation.
• 31 Jan 2020:
  • Design of the facility will be frozen.
  • First view of the costs.
  • R&D programme needed to realise LhARA and be able to write a technical design report will be defined.
• 28 Feb 2020: Complete the write-up of the pre-CDR.
• Mar 2020: External review of pre-CDR in advance of publication.

Floor plan

• Version 0 of the floor plan​
• Updates
  • Laser
    • Need two separate rooms, one for the laser system itself (12x5 m) and a second for the target chamber (5x5 m).
    • These need to be separated by an interlocked shutter.
    • Fit the 12x5 m room within the foot print of the version 0 floor plan, if possible.
  • Capture
    • Check version 0 of the floor plan includes sufficient space for power supplies.
  • Beam transport details to be updated/added:
    • Physical radius of FFA.
    • Transfer line to the FFA injection system.
    • Abort line at 15MeV (most likely to be just after the Stage 1 vertical arc for fail-safe operation).
    • Stage 2 extraction line and transfer line to the in vivo end station.
    • Stage 2 vertical bend to the second in vitro end station.
    • Abort line at 127 MeV.
    • Location of rebunching cavities.
    • Location of collimators.
    • Power supplies for magnets.
    • Power supplies (and klystrons?) for RF cavities.
  • End station
    • First draft of in vitro end station floor plan.
    • Can be re-configured to allow two end stations in Stage 2.
    • Current space for in vivo end station is sufficient.
    • The space needed for animal holding will not be included in the pre-CDR (the need for this will be mentioned in the pre-CDR).
  • Radiation shielding
    • Around laser target vessel.
    • Around collimators.
    • Around beam dumps?
  • Infrastructure
    • Access to basement for installation, etc.
  • Instrumentation
    • Beam diagnostics.

R&D Plan

• Laser
  • No major R&D needed since it will be a commercial system.
• Proton and ion capture.
  • Gabor lens performance verification.
• Stage 1 beam transport.
  • No major R&D needed.
• Stage 2 beam transport.
  • FFA: Magnet design and prototyping.
  • FFA: RF cavity.
• Instrumentation.
  • Dose calibration for high-intensity beams.
  • Online dose monitor.
  • Online beam monitor for low energy beam.
