The dynamical Casimir effect is the only way to observe the electromagnetic wave from the vacuum by oscillating the boundary wall of the RF cavity.However the existing technology such as piezo electric device to obtain the ultrasonic wave is much less than the required power In this research, the electron driven high power ultrasonic source was developed to oscillate the wall of the superconducting cavity. The RF output from the vacuum was measured using ultra low noise amplifier.

动态卡西米尔效应是观测真空中电磁波的唯一途径，它通过振荡射频腔的边界壁来实现。然而，现有的压电器件等技术获取超声波的功率远远小于所需的功率，本研究开发了电子驱动的高功率超声源，用于超导腔壁的振荡。利用超低噪声放大器测量真空的射频输出。
