Preparation of pre-CDR for LhARA

Last updated: 17Dec19 [KL]

Preparation of LhARA pre-CDR for publication

The heading for this section is a link to the page in which information sharing for the preparation of the pre-CDR for publication is being collected.

"Old" (static) LhARA pre-CDR preparation page

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.

Contributions to the write up can be found here.

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 simulation.
  • 31 Jan 2020:
    • Design of the facility will be frozen.
    • First view of the costs.
    • The R&D programme needed to take the programme forward will be defined.
  • 28 Feb 2020: Complete write-up of the pre-CDR.
  • 31Mar 2020: External review of pre-CDR in advance of publication.

Information sharing page for preparation of Lay Summary of LhARA pre-CDR

The page linked from the header of this section has been prepared to share information with the Charing Cross Hospital PPI group in preparation of a lay summary for the pre-CDR and for the publication.

Pre-publication review of LhARA pre-CDR

The pre-publication review of the pre-CDR is being organised using the pages linked from the header of this section.

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 (including rebunching and sweeper magnets for spot-scanning) 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
      • Version 2 of the in vitro end station floor plan. This includes the beam housing for in vitro experiments in Stage 2.
      • 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?
      • Around high momentum in vitro end station.
    • Infrastructure
      • Access to basement for installation, etc.
    • Instrumentation
      • Beam diagnostics.

R&D Plan

Version 2 of the project plan xml and pdf

  • Laser-driven source
    • No major R&D needed for the laser since it will be a commercial system.
    • Target particle production and diagnostics.
  • Proton and ion capture.
    • Gabor lens prototype development and performance verification.
  • Stage 1 beam transport.
    • No major R&D needed.
  • Stage 2 beam transport.
    • FFA: Magnet design and prototyping.
    • FFA: RF cavity performance verification.
  • End station
    • Automation.
  • Instrumentation.
    • Dose calibration for high-intensity beams.
    • Online dose monitor.
    • Online beam monitor for low energy beam.
    • Fast feedback monitoring and control.

Instrumentation

A number of systems will require diagnostic devices and these will be coordinated by the instrumentation work package. Currently it is envisaged that there will be the need for devices that will characterize the beam intensity and energy; dose monitoring, in particular online 2-D dose profile monitors; and dose calibration for very high intensity beams. The two existing detector development projects (the SmartPhantom and the SciWire) can act as a starting point for developing these. The need for monitoring and fast feedback to tailor the way irradiations are delivered can be included in the Instrumentation work packge as part of the R&D plan.

Simulation

Details of simulations for the pre-CDR can be found here.
