permeability measurements (Vladimir B.)
- 5% uncertainty; calibrated by 1.36 sample
- various materials for hardware in the DS
- operating at edge of operability of the device
- 3D printed a holder so that the distances are uniform
- set up almost ready for QA measurements
- Questions
  - Silicon Bronze tested in past
  - how else does 485 come (besides rods)?
    - very accurate, consistent OD on rods
    - can come in bars
sims on fasteners (Kent)
- 1E-3 good for most things
- sim: 4E-3, 6e-3 - good luck that limit of Ferromaster is 1e-3
- most sensitive in TM4 region
- Update SRD: the fasteners in their current positions require susceptibility less than 0.002. If fasteners are added or moved, then the susc. limit would need to be re-evaluated; bulkead items have not yet been completed evaluated
FEA results of the DS belly plates (Kris C.)
lintel study results (Prakash)
