Abstract: A dewar for storing a cryogenic fluid features an inner vessel configured to store the cryogenic fluid and an outer vessel having an outer upper head and an outer lower head. The outer upper and lower heads are joined so as to define an interior chamber of the dewar. The inner vessel is positioned within the interior chamber of the outer vessel so that an insulation space, which is evacuated of air, is defined between the inner and outer vessels. A neck extends between the inner vessel and a central region of the outer upper head. The outer upper head and neck are configured so that the central region permanently deforms without breaking the neck when excessive shock loads are applied to the dewar.
