Environmental scanning electron microscopy enables observation of samples in environment with elevated pressure. Ionization detector is one of several types of detectors used at conditions of higher pressure in the specimen chamber. It detects signal of secondary and backscattered electrons. Its circular electrode is placed above the specimen and creates an electrostatic field in the space between specimen and detector. Signal of electrons is amplified in this field in the process of impact ionization and is detected by this electrode.
