short-circuit current density

Among them, a better quality beam can be easily obtained from the thermionic cathode, but the emission current density of the electron is relatively low, the cathode is short life due to an easily cathode poisoning, and the cost is expensive.

其中，热阴极获得的电子束的束流品质较好，但发射电流密度相对较低，阴极容易中毒，寿命较短，而且成本高。
