SOVIET RESEARCR ON TRAVELING-WAV. TUBES
Information from overt Soviet periodical literature indicates that at pres-
''nt at least three groups in the USSR are conducting research on traveling-wave
tubes.
The most active of these groups, judged from the number of papers published,
is located at the Physics Institute of the Moscow State University. This group
is apparently led by V. M. Lopukhin, since he is author or coauthor of each paper,
and is apparently under the over-all supervision of Professor S. D. Gvozdover,
since he is thanked in each case by the authors. The Moscow State University
scientists have been concerned primarily with the type of structure used to ob-
tain reduced phase velocity .f the electromagnetic waves in the traveling-wave
tube. They have also annlv,o.l th- eff_ctc cf the ^^lc^'t;- di:trlh tlon
trons in the stream. tapers published by scientists in this group are listedein
the appended bibliography under Group I.
A second group, apparently headed by A. I. Akhiyezer, since he is coauthor
of each paper, is conducting research on traveling-wave tubes at the Physicotech-
nical Institute of the Academy of Sciences Ukrainian SSR. These scientists have
been analyzing the operation of a traveling-wave tube, the feature of their
analysis being the assumption that the actual delaying device can be replaced by
some medium with an effective dielectric constant greater than unity. Papers
published by scientists in this group are listed in the appended bibliography
under Group II.
Research on traveling-wave tubes is also being conducted by a group consist-
ing of L. N. Loshakov and Ye. B. 01'derogge. These men have been studying the
effectiveness of a coaxial spiral line as a device for slowing down electromag-
netic waves. No indication of the present location of this group has been found,
but Soviet Men of Science (CIA/CD 1) lists Loshakov as a member, in 1945, of the
Scientific Research Laboratory of Artillery Apparatus Construction of the Red
Army. Papers published by Loshakov and 01'derogge are listed in the appended
bibliography under Group III.
