Changes of the electron work-function of a superconductor proportional to the square of the current density $\Delta \varphi =-\beta j^2$ are known as Bernoulli effect in superconductors or current induced Contact Potential Difference (CPD). The temperature dependent coefficient β(T; m*) is parametrized by the effective mass of Cooper pairs m*. In such a way the study of the Bernoulli effect leads to creation of Cooper pair mass-spectroscopy. In this paper a short review on the Bernoulli effect in superconductors is given and a proposed experimental set-up for its measurement is described in detail. The experiment requires standard electronic equipment and can be implemented in every laboratory related to physics of superconductivity. This experimental set-up for observation of current induced CPD requires nano-technological hybrid superconductor structures with atomically clean interfaces and measurement of nano-volt signals with capacitive coupling to the sample. As the quality of the superconductor surface is crucial for the proposed experiment the research is better to start with crystals used for angle-resolved photo-emission spectroscopy (ARPES); all those samples have excellent quality guarantying success even for the first experiment.

超导体的电子功函数的变化与电流密度的平方成正比 $\Delta \varphi =-\beta {Ĵ}^2$在超导体中被称为伯努利效应或在电流中引起的接触电势差（CPD）。温度相关系数β（T; m *）由库珀对m的有效质量参数化*。这样，对伯努利效应的研究导致了库珀对质谱的创建。在本文中，对超导体中的伯努利效应进行了简短回顾，并详细描述了用于测量其的提议实验装置。该实验需要标准的电子设备，并且可以在每个与超导物理学有关的实验室中实施。这种用于观察电流感应CPD的实验装置需要具有原子清洁界面的纳米技术混合超导体结构，并需要通过电容耦合到样品来测量纳伏信号。由于超导体表面的质量对于拟议的实验至关重要，因此最好从用于角度分辨光发射光谱（ARPES）的晶体开始进行研究。
