Vacuum acquisition systems and methods

A system for acquiring a vacuum level in a space of a container comprising:

• at least one roughing pump;
• a turbo pump;
• a cryogenic pump;
• a vacuum manifold, wherein the at least one roughing pump, the turbo pump, and the cryogenic pump are fluidly coupled by, conduits to the vacuum manifold, and wherein the vacuum manifold is fluidly coupled to the space of the container;
• and
• a controller configured to control operations of the at least one roughing pump, the turbo pump, and the cryogenic pump, wherein
• the controller is configured to:
• control the at least one roughing pump to evacuate the space;
• initiate supplying a gas into the space to purge the space;
• control the turbo pump to further evacuate the space;
• and
• control the cryogenic pump to condense air in the space and remove water vapor from the air, wherein
• the controller is further configured to operate each pump for a predetermined period of time and to determine a vacuum level of the space after each predetermined period of time for each of the roughing pump, the turbo pump, and the cryogenic pump,
• wherein the controller is further configured to:
• operate the roughing pump for a first predetermined period of time and until a first predetermined vacuum level is reached in the space;
• operate the turbo pump for a second predetermined period of time and until a second predetermined vacuum level is reached in the space;
• and
• operate the cryogenic pump for a third predetermined period of time and until a third predetermined vacuum level is reached in the space,
• wherein the first, second, and third predetermined periods of time are different amounts of time;
• an oven in which the container is placed during a vacuum acquisition process.
