From January 1, 1949, to March 18, 1949, I was stationed at the R.C.A. tube plant in Harrison, New Jersey, to work with the Advance Development Section. This period constituted the winter term of the third year in the course in engineering electronics at the U.S. Naval Post Graduate School, Annapolis, Maryland. Because I was interested in working with vacuum tubes in the microwave region, I was assigned by G.M. Rose, in charge of the Advance Development Section, to work with W.A. Harris on a project to measure the input admittance of the pencil tube triode at ultra high frequencies. I became interested in the problems encountered in the operation of the space charge control vacuum tube triode at ultra high frequencies during this time and started research for this thesis in the excellent library at the plant. It is an important subject in the light of present-day trends in television, UHF communication, and radar.
