| Walk - in / out | | - KB mirrors. Asked Diling why XPP goes with transfocator, not KB pair.
- Per Diling: Much easier to change spot size based on XPP user requests
- Based on Diling's experience, our flexibility to change focus on demand is reduced.
- Long effort for changing focus in current implementation.
- This goes away from what David Fritz says. Diling has never seen this in practice. Diling not sold on the ease of changing focus with mirror bending.
- Worrisome that this is something that is possible in principle but worry about practice
- Achromaticity is a sure benefit
- KB implies a different path through the chamber than lenses.
- Experiments go als
- Also discussing beam path below grade and what control room we would use.
- MEC-U's current standpoint is the CDR plan or else using the space of TAO (ROD 16). Using the current MEC control room was a last resort concept. Note I link to the records of decision page here
- Possibility of beam path going below CXI line (slightly offset by CXI)?

| Technical updates |
| - ELI Beamline photos from Eric, Dimitri and Meriame
- Discussion of stalled MEC-U UAP meeting
- Scope conversations
- Kai is asking engineers to refer to a facility not supporting the upgrades in CDR 11.2 not as "FES Base" but rather "FES minus explicitly designed upgrades" ("FES -EDU")
- Cavern space looks very constrained when considering beam delivery, dumping and access.
- Mikael has a request to consider what the impact would be of living in FES -EDU world.
- Requirements transcription into Jama - needing help
- Engineers are working from one incomplete slide deck to figure out requirements - slide deck had a configuration (inadvertently?) deleted back in September.
- As a consequence, Brice was surprised to learn that we might want a dual target for some experiments (e.g. ion heating target)
- Flagship descriptions into Jama. One presentation is here
- Considering a different mirror to put MEC below floor at final FEH location. Discussed this morning
- Very preliminary discussion
