Abstract
A device includes a plurality of evaporators coupled to a payload bay with a multiplicity of coolant tubes in each evaporator, wherein each tube enters and then exits the payload bay, further comprising one or more cryogenic valves coupled to the coolant tubes; a pump to force coolant flowing through the evaporators; and a thermal box immediately outside the evaporators and payload bay to thermally seal the payload bay from the outside environment and reduce heat gain, the thermal box including high strength open cell panels and a vacuum or Vacuum Insulated Panels (VIPs) with polyurethane foam to fill the voids.
