Abstract
A method for using a shape memory alloy (SMA) with a non-evaporable getter (NEG) employed in a vacuum device is disclosed. The method comprises coupling a NEG component to a SMA component to form an NEG/SMA assembly pair; heating the NEG/SMA assembly pair to activate the NEG component; and packaging the activated NEG component with the SMA component to form an NEG/SMA package having a gas tight seal. The method further comprises installing the NEG/SMA package in the vacuum device; and heating the installed NEG/SMA package such that the SMA component is actuated to expose the activated NEG component to a vacuum chamber in the vacuum device.
