secondary emission


secondary emission
 Secondary Emission
 Вторичная эмиссия
  Испускание элементарных частиц веществом, например, газом или металлической поверхностью, при бомбардировке его первичным (только что порожденным) излучением или частицами. Так, вторичные космические лучи испускаются при бомбардировке атмосферы первичными космическими лучами, а анод электронной трубки испускает вторичные электроны при его бомбардировке первичными электронами из катода. Этот принцип применяется в фотоэлектронных умножителях, например, в усилителе изображения.
