1. Status of the engineering work
   1. Update from Jason on support structure
      1. green and blue are Al strongbacks; pink blocks are Al with coil
      2. slide 7 doesn't include bolted connections
      3. Slide 9 Questions:
         1. Could top piece be an I-beam? - Needs strength in both directions.
         2. Is this assembly made and then assembled? - yes - coil is pre-assembled with carrier.
      4. Slide 10 Questions:
         1. Isn't ~1mm too big? Comparison is between clamped vs. 6 strut. But aren't they both too big? Small perturbation and sensitivity study (not completed yet) seems to indicate that this would be okay. Also doesn't include the other braces - just has carrier and coil.
         2. Why strut - why not another support structure? Takes more alignment...
   2. Update from Jim on vacuum vessel
2. Update on the physics/optics work
   1. Update from Juliette on iron simulations
