Microwave apparatus for the measurement of the refraction, dispersion and absorption of gases at relatively high pressure

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

An apparatus of high sensitivity is described using a single frequency modulated klystron oscillator. The resonance curve of a sample cavity is compared to the one of a reference cavity by means of an electronic device using microsecond pulse technique. Without special precautions the sensitivity for measurements of the power absorption coefficient is 10-5 m-1 and 10-8 for the refractive index.

Riassunto

In questa nota viene descritto un apparecchio per misure del coefiiciente di assorbimento e dell’indice di rifrazione di gas a pressioni relativamente elevate, costruito nell’Istituto di Fisica dell’Università di Pisa. Confrontando mediante una tecnica ad impulsi due cavità risonanti opportunamente aecordate, viene ottenuta una sensibilità di 10-8 nelle misure dell’indice di rifrazione e di 10-5 m-1 nelle misure del coefflciente di assorbimento.
