Advances in Electronics and Electron Physics, Volume XIV

Abstract

Edited by L. Marton New York and London: Academic Press Inc. Pp. x + 341. Price $ 11.00 This latest edition of Advances in Electronics includes six survey papers entitled The Electron as a Chemical Entity, Problems of Photoconductivity, Strong-Focusing Lenses, Hydrogen Thyratrons, Cerenkov Radiation at Microwave Frequencies, and High-Power Axial-Beam Tubes. More than one-third of the book is given to Strong-Focusing Lenses, by which is meant electron lenses consisting of 4 poles (or electrodes) arranged like the 4 poles of the stator of a d.c. machine and providing a magnetic (or electric) field which has constant radial gradient ∂H/∂r (or ∂E/∂r).
