Ionisation chambers
WebThe problem of electron adnesion to electro-negative admixtures during the operation of an ionization chamber with a grid is discussed. It is shown that the addition of gas mixtures reduces electron adnesion to a minimum. A formula was derived for determining the number of electrons lost in the adhesion.
