  1. Thermal Isolation Layer (TIL) Design +Z Counterbored#4 screw +Y DASS Press-fitthreaded insert MLI Blanket Torlon 5030 Standoff E-Box Countersunk #2 screw Countersunk #2 screw Aluminum backstop

  2. Thermal Isolation Layer (TIL) Mechanical Design +Z +Y 6.35mm DASS 2mm 6.07mm 18.57mm MLI Blanket 12.5mm 4.76mm 2mm 3.18mm 9.53mm E-Box 15.88mm 4.76mm 22.23mm

  3. Torlon Standoff Key feature (to prevent rotation on installation) Standoff solid portion Standoff hollow portion for accepting press-fit insert Standoff head (also acts as a washer)

  4. Subassembly View Aluminum backstop (contains recess for head with 0.001” of clearance on all edges) Epoxy backfill would go here Threaded insert Note: E-Box top is transparent

  5. Assembly View TIL screws counterbored into DASS TIL

  6. Changes from PDR • Geometry of standoffs has changed based on Kevin’s calculations and my design work • Standoff bolt pattern has not changed, so FEM should be easy to modify • Instrument would be 6.07mm taller with this design • Aluminum backstop, possibly with epoxy backfill as recommended by MIT Kavli’s Rick Foster • Key feature in Torlonstandoff head to prevent rotation on install • Threaded insert in Torlon standoff • Need to ask Rick why ACIS and Suzaku seemingly did not do this
