Эктон — лавина электронов из металла


Физический институт им. П.Н. Лебедева РАН, Ленинский проспект 53, Москва, 119991, Российская Федерация

Показано, что при микроскопических взрывах на поверхности катода возникает эмиссия электронов в виде отдельных порций или лавин электронов, названных нами эктонами. Возникновение электронов в эктоне обусловлено перегревом металла при микровзрыве за счет большой плотности энергии (104 Дж г-1), а прекращение — охлаждением зоны эмиссии. Эктоны имеют место в электрических разрядах в вакууме и в катодном пятне вакуумных дуг, в объемных газовых разрядах, в псевдоискровых и коронных разрядах и т.д.
