摘要:

For direct measurements of electron intensities in the image plane of the RCA electron microscope a scanning electrometer device has been designed. It consists of a probe and preamplifier, a mechanical drive, an amplifier, and a recording unit. A linear resolution of 0.06 to 0.92 &mgr; is achieved. Sensitivity range is 10−12−10−11amp.
