A getter assembly (38) includes a porous getter element (40) having an outer periphery (44), and a porous, thermally conductive, annular getter support (42) overlying the getter element (40) and contacting the outer surface (44) of the getter element (40). The getter assembly (38) further includes a wall (24) sized so that the annular getter support (42) is received within the wall (24) with a friction fit between an outer periphery (50) of the annular getter support (42) and an inner periphery of the wall (24). The getter support (42) supports the getter element (40) from the wall (24) and provides a thermally conductive pathway from the wall (24) to the getter element (40). The annular getter support (42) is typically a screen, a mesh, a felt, or a foam, which is deformable to conform to the inner wall (24) and to slide into the wall (24) with a friction fit that ensures good thermal contact.
