Wrapping the aluminized-mylar MLI onto the G10 shell insert. The
approach was to lay down about 10 layers, then cut the MLI, tape it
down, and start again. This reduced the thermal conduction along the
MLI while achieving good thermal insulation. The final layer count
was 120. Or was it 121? Dang.. |

Domenic peeking in to see how we were doing on wrapping the MLI
onto the G10 shell. I seem to recall his comment was "Hmmm."

Alex Grabau taping the ends down after 10 more layers of MLI had
been added. The latex gloves were used to keep skin oils out of the
MLI wrap. Unfortunately, latex gloves and adhesive tape are a complex
combination to master together. |
 |
Alex did get pretty good at it, though... |
 |
In the end, it worked! The G10 insert supports the 120 MLI layers
so they just don't quite touch the stainless steel cryostat shell
and the G10 insert nests over the aluminum active cold shield that
encompasses the filter box and cold bulkhead volume. |
