Aperture cylinder
Today they installed the aperture cylinder. This sits in a hole above me in the neon dewar. This cylinder keeps water vapor that's in the thermal blankets from getting onto the filters. It's about the size of a soda can, and has baffles in it to keep the water from going from the warm outside to the colder inside. The cylinder gets installed first, and in a couple days they'll install the filters inside it.
