Abstract:This paper describes a convenient scheme for detecting and measuring vibration as related to the performance of an RCA electron microscope (Type EMU). The procedure involves the use of a Webster Model F5P2 phonograph pick-up arm in conjunction with a cathode-ray oscillograph. The cathode-ray oscillograph signal amplitude which represents the vibration of the location being investigated was calibrated by means of a Brush Development Company Type BL-301 vibration pick-up whose voltage output is proportional to t… Show more
