Hey everyone, Alan Conder has asked me to put together a retreat to verify the cavern size is sufficient and that we are not over constraining the facility.
I have put together this rough agenda and charge of how we might structure a day to get together with all our stakeholders and hash everything out. The plan is to try to hold this retreat the week of October 31st. Please take a look and let me know what you think. Once we agree on the agenda, charge and attendees, I’ll send this to Ji for her to schedule with everyone.
Topic | Time | Duration (minutes) | Attendees | Charge |
Introduction | 8:30am | 30 | All | Go over scope of retreat, show overall cavern layout, highlight pinch points, present schedule.
Main charge. - Is the cavern layout over constrained?
- Are we setting ourselves up for failure with our current cavern size, or is it sufficient to deliver the goals of the project?
- If we do find out we are over constrained in the future, does an increase in cavern length easily fix the problem, or do we need a wider cavern?

HELP Laser Hall Layout Review | 9am | 60 | LLE/LLNL/ILS Team | Review HELP Laser and Beam transport layout in this area. - Do we have the correct size for the laser and amplifier?
- Have we given enough room for the harmonics and diagnostics in the amplifier stage?
- Are the racks laid out sufficient?
- Is the system serviceable?
Review the Beam transport layout in this area - Is the beam transport interface proper?
- Is the beam transport system serviceable?
Are we over constrained? |

RRL Laser Hall Layout Review | 10:15am | 90 | LLE/LLNL/ILS Team | Review RRL Laser Layout in this area. - Do we have room for all the optical components we will need (i.e. DM, diagnostics, fast steering mirror, number of front ends, etc.)?
- Is the system serviceable?
Review the Beam transport layout in this area - Is the beam transport interface proper?
- Is the beam transport system serviceable?

Mezzanine Layout Review | 1pm | 60 | LLE/LLNL/ILS/Controls Team | Review RRL Laser Equipment in this area. - Do we have enough racks to support the RRL?
- Are the chillers and helium blowers serviceable?
- Are access pathways proper?
Review HELP Laser Equipment in this area. - Do we have proper space and access for the PCUs?
- Do we have enough racks for to support the PCUs?
- Are the racks close enough to the laser to perform properly?
- Are access pathways proper?
Review the LCLS Controls Equipment in this area - Do we have enough racks in this area?

Experimental Systems Layout Review – Laser and X-ray beam transport | 2pm | 60 | ILS/ES Team, LLE/LLNL optional | Review Laser Beam transport layout in this area - Do we have room to get the beams from the laser hall into the target chamber?
- Is there a feasible path to a support structure that can hold these optics properly?
- Is the beam transport system serviceable?
Review X-ray Beam Transport layout in this area - Is there a feasible path to providing a stable platform for X-ray beam transport to be placed on with all the laser beam transport conflicts beneath it?
- Is the length of the X-ray transport alcove sufficient to support the requested beam transport components?
- Is the x-ray beam transport system serviceable?
Are we over constrained?

Experimental Systems Layout Review – Experimental Systems | 3:15 | 45 |
| Review ES layout in this area - Given the laser and x-ray beam transport layouts, does the current chamber size give us a path towards success? (do we have room for laser ingress and the diagnostics required for the project)
- Do we have room for the diagnostics we need for the project?
- Is the target area serviceable?
Are we over constrained?

Closeout Summary | 4pm | 30 | All | Summary of issues discussed. Clean up notes |
Closed Session | 4:30pm | 30 | Management team, System Managers, Tom?/Liz? | We will have had a full day of debate and likely some topics at which we will have disagreement on. Let’s discuss to ensure we have a unified path forward from the project leadership team. |
