Ph. Bernard, G. Gemme, R. Parodi, E. Picasso

摘要:

本文介绍了一种基于两个耦合微波腔(PACO)的小谐波位移检测器的射频控制和检测系统。该检测器的基本思想是系统的两个谐振模式之间的参数功率转换的原理,由一个系统参数的(小)谐波调制刺激。在这个实验中,我们改变腔的长度施加一个谐波电压到压电晶体。该系统可以实现一个很大的灵敏度,小的谐波位移,可以是一个有趣的候选人,用于检测小,机械耦合,相互作用(例如,高频引力波)。

英文摘要:

In this technical note the rf control and detection system for a detector of small harmonic displacements based on two coupled microwave cavities (PACO) is presented. The basic idea underlying this detector is the principle of parametric power conversion between two resonant modes of the system, stimulated by the (small) harmonic modulation of one system parameter. In this experiment we change the cavity length applying an harmonic voltage to a piezo-electric crystal. The system can achieve a great sensitivity to small harmonic displacements and can be an interesting candidate for the detection of small, mechanically coupled, interactions (e.g. high frequency gravitational waves).
