Operation and Development of Gravitational Wave Detectors at LSU

一个由三个引力波探测器组成的国际网络目前正在运行。 每个探测器在引力应变中有一个大约6 x 10-19的单独噪声水平，并且探测器在协调操作中寻找引力波的同步探测。 路易斯安那州立大学小组计划与意大利小组和澳大利亚小组的探测器一起继续运行其探测器。 将研究信噪比对引力波脉冲到达时间估计的影响。 与其他探测器同时进行的持续操作将寻找振幅为10-18或更小的引力波脉冲。 如果没有观测到，引力通量的下限将被扩大到更低的值。 研发将继续开发谐振器-换能器-放大器，该放大器是路易斯安那州立大学天线出色性能的保证。 这将包括继续与马里兰州大学合作，为谐振换能器开发坚固而灵敏的SQUID放大器。 此外，将继续发展该小组开发的TIGA先进探测器概念。

An international network of three gravitational wave detectors is now in operation. Each detector has an individual noise level of approximately 6 x 10-19 in gravitational strain, and the detectors are in coordinated operation to look for coincident detection of gravitational waves. The LSU group plans continued operation of its detector in conjunction with the detectors from the Italian groups and the Australian group. Studies will be performed on the effects of signal-to-noise ratio on the estimates of time of arrival of a gravitational wave pulse. Continued operation in coincidence with these other detectors will look for gravitational wave pulses of amplitudes 10-18 or smaller. If none are seen, the lower limit of gravitational flux will be extended to lower values. R&D will be done on the continued development of the resonator-transducer-amplifier that has been responsible for the outstanding performance of the LSU antenna. This will involve continuation of the collaboration with the University of Maryland to develop robust and sensitive SQUID amplifiers for resonant transducers. In addition, there will be continued development of the TIGA advanced detector concept developed by this group.
