Abstract
Apparatus is disclosed for retaining an electrically fired getter inside a ring laser gyroscope. A groove is formed in a plate, which is hermetically sealed to a hole in the ring laser gyroscope block. The cylindrically shaped getter is placed longitudinally in the groove such that the getter contacts the groove along only two lines. A mousetrap shaped spring preloads the getter against the groove so as to prevent acceleration forces and vibrations from causing pieces of the getter, heater coil or wire to break loose.
