many physics experiments look like this. I've always been bothered by the use of aluminum foil for insulation but it works. a lot of the parts would have been precision cut using CNC, etc.
I spent years using the Department of Energy's giant X-ray generators, and foil wrappings are extremely common at the experimental endstations. My favorite however was the scientist who custom-built a robotic arm that for many years used wooden pencils as part of the gripping hand. (I'm still not sure why he used pencils, except they were exactly the right size and physical properties. The robot worked, anyway.)
Aluminum foil is used on a bunch of spacecraft as well. The Voyager spacecrafts use aluminum foil bought at grocery stores (and then laid out in sheets and thorough scrubbed with bleach).
Yessir. A lab I worked in had what had to be a $10M MBE, half covered in aluminium foil.
Just to clarify, the aluminum foil is for thermal insulation used for keeping the microscope warm?
Al-foil is ubiquitous in ultra-high vacuum labs because part of the process of reaching this vacuum level involves baking the whole chamber at 120-150dC for 24+ hours. The chambers are typically made of stainless steel which has a pretty mediocre thermal conductivity. Hence the Al-foil, to ensure even heating during the bake. Since you have to bake every time the chamber is opened, it’s easier to just leave the foil on.
