1. A time-of-flight mass spectrometer assembly for installation into a vacuum chamber, the time-of-flight mass spectrometer assembly comprising:
a flange configured to be secured to an opening of the vacuum chamber, the flange comprising a body including a vacuum chamber facing surface and an environment facing surface, wherein the body further defines a cut-out portion that extends between the vacuum chamber facing surface and the environment facing surface;
a plurality of stacked spectrometer components supported by the vacuum chamber facing surface of the flange and configured to be positioned inside the vacuum chamber;
a secondary flange configured to be removably secured within the cut-out portion to close-off the cut-out portion, wherein the secondary flange comprises a vacuum chamber facing surface and an environment facing surface; and
a supported component configured to be coupled to the vacuum chamber facing surface of the secondary flange,
wherein removal of the secondary flange from the flange acts to remove the supported component from the vacuum chamber while keeping the flange secured to the opening of the vacuum chamber.
