<p>A cathode ray tube (CRT) has a getter attachment wand (13a) with a trough shape along a substantial portion of its length, imparting an increased stiffness to the wand to maintain the wand in close proximity to the inside surface of the CRT envelope, thereby avoiding clipping of the electron beam (20) on its way to the screen. An optimal curvature of the wand (13a) strikes a balance between the desired stiffness and the ease with which the wand can be resistance-welded to the top cup (14a) of the electron gun assembly.</p> |
