‘Cesium migration’ may give clue to new family of electronic devices

An accurate means of evaluating new anode and cathode materials for thermionic converters without the problems posed by very high temperatures may be one outgrowth of basic investigations at Martin Company's Research Institute for Advanced Studies (RIAS), Baltimore, Md. The work is being performed under a contract from the U.S. Air Force's Cambridge Research Laboratories, Bedford, Mass.
