I had an idea for a low cost way to quickly bake-out (dry out) a vacuum chamber.
At one point I read that the fastest way to bake-out a vacuum chamber was with x-rays (I can’t find the link). But assume for a second this is true.
Now. Consider the fact that we can make x-rays very cheaply with scotch tape in a vacuum. And in our case, we are already operating inside a vacuum!
Cheap,fast, high quality vacuum chamber bake-out.
It would look something like this:
