Abstract:
Photomultiplier tubes with a suitable electrode structure were investigated for use in a superheterodyne-type signal receiver for the Doppler shift laser velocimeter LV. An oscillator signal impressed upon specially constructed electrodes within the photomultiplier tube produced a signal at a frequency which was the difference between the oscillator and the LV signal frequencies. The high gain of the photomultiplier tube then amplified the difference frequency signal to a usable level. Two different tubes were investigated and found to be useful as heterodyne photomultiplier tube amplifiers. The circuit design, experimental results, and applications are discussed.
