Descriptive text: This photograph shows three men in long-sleeved blue jackets, blue gloves, and red hard hats. They’re standing around a thermal vacuum chamber, which has a square silver base and a conical white top. On the left, a man hands a wrench to another man, who is standing on the base of the chamber. On the right, the third man looks up at the top of the chamber. They are in a lab with a high ceiling and lots of electrical equipment. An American flag hangs from the ceiling.
