Guzgan // Relevanţa şi calitatea formării universitare: competenţe pentru prezent şi viitor : Materialele conf. şt. intern. : consacrată celor 70 de ani de la fondarea univ. bălţene din 8 oct. 2015. – Bălţi, 2016. – Vol. I. – P. 142-144. – ISBN 978-9975-50-177-4.The paper presents results of experimental investigations aimed at the construction of cathodes for thermo-electronic emission. The method of pulsed electrical discharge machining was applied to confer a prescribed micro-geometry of the cathode active surface. Modification of the cathode surface micro-geometry involves the extraction and freezing of the Taylor cone meniscuses that are electric field and heat concentrators applied in order to increase the intensity of the thermo-electronic emission current.roAttribution-NonCommercial-NoDerivatives 4.0 Internaționalelectrical dischargesmicro-geometrythermo-electronsemissionmeniscusemisie termo-electronicădescărcări electricemicro-geometrieArticle
