Attended: Juliette, Seamus, Cameron, Jim, Ernie, KK
- Preparation for MOLLER tracking meeting - status
- Need to go back to reviewers and ask what they meant, if we need to
- create a timeline for next 6 months
- Radiation dose estimates/material irradiation summary
- have located some "hot spots"
- need to convert to doses
- compare to radiation hardness for various materials (epoxy, insulating tape)
- quantify known materials, is it good enough for MOLLER
- Upstream sensitivity studies summary
- Beamline fringe field effects
- MIT activities
- impact of environmental variations
- expanding and contracting uniformly (that's how water system is being designed)
- heat load on hot day - just run hotter
- we need to cool our water anyway - our refrigerator design
- floor loading - probably not a concern (each component less than what crane can lift)
- spring of '18 - would floor sagging affect physics?
- shielding around target bigger issue
- dialogue between MIT and survey group
- does target sinking affect rest of experiment?
- impact of environmental variations
- beamline - Silviu's designer
- downstream of vacuum vessel - exit window
- coupling between vacuum vessel and beamline
- Also need to list things that we want to keep working on that aren't on the list
- collimator supports
- movable collimator - needs work - concept based on SLAC design
- need space where shielding might exist right now
- linear stage and hard stop
- water-cooled collimator
- same system as coils
- feasibility with cooling and physics
- budgetary bids only
- upstream vacuum vessel
- inner-photon collimator - independent of motion of chambers
- Test coil status/homework
- Objectives
- Test plan
- Schedule
- Next meeting
