Raytheon QK-329 Beam Deflection Squaring Tube
				  Tube utilisé dans le domaine du calcul analogique (loi quadratique)
				  Röhre entwickelt für Anwendungen im Bereich der elektronischen Rechenschaltungen (square-law detector)
			  Introduced in 1958, this beam-deflection tube was used in early analog computers.
              The principle employed to produce a square-law characteristic in this tube
			  is that of deflecting a flat sheet of electrons across a target electrode
			  containing parabolic apertures.

              Early tubes had the internal elements arranged horizontally.
