Figure 2: Drawing of the C--cage structural unit. Silicon wafers are glued to the faces of the cage. This drawing also shows the location of the various widths, radial distances and lengths that were measured in the lab tests.

Figure 3: Results of robustness on Parylene coated Rohacell strips. Graph is showing Thickness of Parylene vs. Number of flakes that have detached from the Rohacell strip.

  
Figure 4: Average change in mass vs. thickness of parylene coating.

  
Figure 5: A partially populated (4 silicon wafers) C--cage assembly with corresponding electronics. The silicon wafers are attached to the electronics via a kapton cable and the electronics are housed in a Rohacell air cooling plenum. A fully populated (6 silicon wafers) has all six faces populated with silicon and two more electronic boards in the plenum.

  
Figure 6: Shows the changes in the widths, radial distances, and length for bare (no silicon wafers) coated and uncoated cages. (a)Shows the average change in widths for bare uncoated and coated cages, (b) for radial distances and (c) for length. All errors are statistical.

  
Figure 7: Shows (a)the avenge change in width for a six-silicon cage without Parylene, (b) the changes in length for an uncoated and coated six-silicon cage. All errors are statistical.

  
Figure 8: Shows (a) changes in width with and without silicon for a four-silicon cage, (b) shows the change in length for a four and a six-silicon cage. All errors are statistical.
