摘要:
Three metal carbide spheres located approximately equidistant on a support with a V‐shaped circular groove allow easy horizontal rotation of a heavy mass in UHV via a turntable residing on the three spheres with vertical axis in the center of the support.

摘要:
An easily installed modification to an electron gun power supply allows the electron beam to be modulated with an externally applied, audio‐frequency signal. Full on–off chopping is accomplished with an input amplitude of only 10 V rms. The modification does not interfere with normal operation of the electron gun.
