GEO 600引力波探测器采用了先进的技术，包括信号回收和单片熔融二氧化硅悬浮体，以实现接近千米级LIGO和VIRGO探测器的灵敏度。一旦达到GEO 600的设计灵敏度，探测器将作为全球网络的一部分运行，以获取具有科学意义的数据。地球同步轨道站点的基础设施有限，无法对探测器进行重大升级。因此，地球同步轨道协作组决定通过小规模的连续升级来提高地球同步轨道探测器的灵敏度，其中一些将首先在原型中进行测试。这些升级的开发、测试和安装被命名为“GEO-HF项目”。本文介绍了GEO-HF项目中考虑的升级及其科学原因。我们将描述GEO 600基础设施的变化以及计划支持这些升级的原型工作。最后，我们将指出一些实验室研究，确定新的技术或光学配置，可能会经历一个过渡到探测器子系统内的GEO-HF项目。
The GEO 600 gravitational wave detector uses advanced technologies including signal recycling and monolithic fused-silica suspensions to achieve a sensitivity close to the kilometre scale LIGO and VIRGO detectors. As soon as the design sensitivity of GEO 600 is reached, the detector will be operated as part of the worldwide network to acquire data of scientific interest. The limited infrastructure at the GEO site does not allow for a major upgrade of the detector. Hence the GEO collaboration decided to improve the sensitivity of the GEO detector by small sequential upgrades some of which will be tested in prototypes first. The development, test and installation of these upgrades are named ‘The GEO-HF Project.’ This paper describes the upgrades considered in the GEO-HF project as well as their scientific reasons. We will describe the changes in the GEO 600 infrastructure and the prototype work that is planned to support these upgrades. Finally, we will point to some laboratory research that identifies new technologies or optical configurations that might undergo a transition into detector subsystems within the GEO-HF project.
