So this tube not only has fine resolution as a result of fast electron scanning, but also has features of slow electron scanning, Thus it is a good mode of operation as high clarity camera tube.

This paper proposes a learning control based high-speed scanning mode for an AFM system.

By means of stereomicroscopy and scanning electronic microscopy (SEM), the fracture mode and mechanism of the broken K18 superalloy cast blade in a supercharger turbo were investigated.
