Our equipment upgrade proposed here is designed to maintain Glasgow and the UK's ability to stay at the forefront of the R&D critical in delivering future science goals at a time when the field is in a period of rapid growth.Much of the experimental work funded by our consolidate grant is in the areas of developing cryogenic silicon suspensions for the next generation of detectors and in designing and measuring improved mirror coatings for the next stages of current detectors as well as for the next generation. To this end we believe that our international competitiveness and overall impact in the field will be significantly enhanced by the purchase and development of state of the art measurement, diagnostic and material preparation equipment. Thus for our bonding and coating research we are requesting funding for an infra-red camera which can enable inspection of bonded silicon interfaces which are otherwise visually inaccessible and support characterisation of scattering properties of coatings at wavelengths where the coatings for future detectors will be required to operate. For our suspension research we are requesting funding for a portable plasma source which can operate in the open laboratory to allow development of activation techniques for the surfaces of the suspension elements which have to be bonded together. This should allow bonds of higher quality and lower loss and lead to the reduction of one of the most important noise sources in gravitational wave detectors - thermal noise from the suspensions themselves and from the mirror substrates. For all quasi-monolithic construction to have ultra low mechanical loss, allowing low thermal noise, surface quality is of the utmost importance both in terms of roughness and figure. Thus we are requesting funding for a Microview interferometric surface profiler from Polytec which should allow us much improved surface diagnostics.We should note that none of our proposed purchases raises any issues with respect to the UKRI Framework for Responsible Innovation

我们在此提议的设备升级旨在维持格拉斯哥和英国保持在领域快速增长的时期实现未来科学目标至关重要的R＆D的最前沿的能力。我们合成赠款资助的实验性工作的实验性工作是在探测下来的近距离型号和衡量标准的领域，用于设计和衡量的领域。下一代。为此，我们认为，通过购买和开发最先进的测量，诊断和材料准备设备，我们的国际竞争力和整体影响将大大增强。因此，对于我们的粘合和涂料研究，我们要求为红外摄像机提供资金，该摄像头可以检查粘合的硅接口，否则这些硅接口在视觉上是无法访问的，并支持在波长处涂层的散射特性，在这些散射特性中，将需要未来探测器的涂料才能操作。对于我们的暂停研究，我们要求为可以在开放实验室中运行的便携式等离子体来源提供资金，以允许开发必须将悬架元件表面的激活技术开发。这将允许更高质量和较低损失的键，并导致重力波检测器中最重要的噪声源之一 - 悬架本身和镜子基板的热噪声。对于所有准石器时代的结构，都具有极低的机械损失，从而使热噪声较低，因此在粗糙度和数字方面，表面质量至关重要。因此，我们要求提供Polytec的微型视图干涉表面剖面材料的资金，这应该使我们大大改进了表面诊断。我们应该注意，我们提议的购买都没有提出有关负责任创新的UKRI框架的任何问题
