Abstract :
A television pickup tube is described which combines in one device the principles of signal storage, as in the Iconoscope, and of signal multiplication by secondary-electron emission. Calculations indicate that for a given video-frequency signal, this tube will generate a considerably greater electrical signal than any other present pickup device.
