Development of Improved Gravitational-Wave Transducers

目前共振质量引力波探测器的灵敏度受到较低的电质量因子和有限的换能器带宽的限制。为了达到第三代超低温引力波探测器的潜在灵敏度，必须对换能器进行重大改进。Paik教授将在斯坦福大学和路易斯安那州立大学构建、测试和交付新的传感器，以配合最灵敏的条形探测器。这种合作将使这些接收器在未来三年内达到新的灵敏度水平。

The sensitivity of the present resonant-mass gravitational-wave detector is limited by the relatively low electrical quality factor and the restricted bandwidth of the transducers. In order to reach the potential sensitivity of third-generation, ultralow-temperature gravitational-wave detectors, significant improvement must be made in the transducers. Prof. Paik will construct, test, and deliver new transducers to work with the most sensitive bar detectors at Stanford and Louisiana State Universities. This collaboration will enable those receivers to reach new levels of sensitivity within the next three years.
