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.
