    摘要: A cathode includes a hairpin type filament made of a refractory metal such as W, Mo or Re; a single crystal needle, made of a refractory metal such as W, Mo or Re joined to the filament; and a reservoir formed by applying a slurry of a powder of a metal or metal compound and an organic solvent containing nitrocellulose in the vicinity of a junction between the single crystal needle and the filament. The powder for a reservoir is made of a metal lower than the single crystal needle in a work function or electron affinity, such as Ti, Zr, Hf, Y, Th, Sc or Se, or a compound thereof.

    摘要: A charged particle beam device radiates a primary charged particle beam of pulse form on a surface of a specimen, once in each clock period, in synchronism with a clock signal that determines an operating period of an internal operating signal of the specimen. A secondary electron or a reflected electron is detected after it is emitted from the surface of the specimen when the primary charged particle beam of pulse form is irradiated. Each detected signal pulse which is generated from the detecting means once in each period of said clock is sampled at two or more positions in a range including the peak value, and data which correspond to the sum or the averaged value calculated from the sampling values of a plurality of the positions are formed. An internal operating signal waveform of said specimen is displayed by using the data, and therefore the internal operating signal waveform of the specimen can be observed and measured with high measuring accuracy and with high efficiency.
