The ionization chamber has two flat electrodes with an area of 300 cm2, the distance between them is 2 cm. The chamber is filled with air under normal conditions. At a voltage of 200 V, the current is far from saturation and is equal to 1.8 μA. Find the concentration of ions and the ionization coefficient of the gas. Ion mobility: m+==1.37·10-4 m2/(V·s), m-==1.89·10-4 m2/(V·s).
