- Setup and Welcome
- Overview (KK)
- Spectrometer Update (Juliette)
- Roger - 100 W still is a large dose - need to check
- Vladimir - can mitigate Bz spikes with ferromagnets
- Kent - optics changes because of changes in position along beamline, not stray fields
- Jay - pivot check that it is less than ~10 G, also look at G4.10.2 paper on Arxiv about e- scattering
- Robin - need to show that hybrid mitigates risk more than segmented
- larger conductor (Ernie)
- Robyn - full ANSYS with deflections
- Vladimir - shrinkage of coils; shear stress on epoxy (different power supplies)
- Dieter - shrinkage probably not an issue
- Jay - power supply specifications, take care of helicity timescale fluctuations
- Roger - shouldn't hurt you (720 Hz line noise) magnet inductance will take care of this
- Jay - Pastor/Martin in Hall B have full ANSYS
- vacuum chamber (Jim)
- buckling of vacuum chamber not an issue (~several times safety factor)
- need to model manufacturing defects
- also reversing chamber and having everything attached to bottom will be investigated
- Discussion - Timeline
- Collaboration Meeting November 11-12, 2016
- MIT produce update (drawings and numbers for larger conductor) end of November
- Receive feedback from committee in early December
- Director's Review December 15-16, 2016
- another teleconference in early March 2017 on manufacturing the prototype
- another teleconference several months in advance of CD1 review, present results of prototype testing
- Hopeful for CD1 review in summer 2017
