Research Abstract |
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.
