The UK Operations program allows continued involvement in the Advanced LIGO gravitational wave detectors, and related data analysis. Continuation of this work enables UK scientists to participate in the rich and exciting science produced by the global network of gravitational wave detectors. The proposal has three work packages (WP) as follows: WP1 - support for LIGO Scientific Collaboration (LSC) detector operations. This provides for continuing UK involvement in the activities of commissioning, operation, detector characterisation and data analysis for the Advanced LIGO detectors. WP2 - support for operation of UK-provided hardware (Advanced LIGO detector components). This provides for the required on-site UK effort to prepare and optimise suspension fibres for newly installed mirrors and to weld mirrors to their suspensions, together with related on-site and off-site support. This work package also provides for optimisation and characterisation of related detector components. WP3 - computational infrastructure and data storage. This provides for the maintenance and operation of the UK's major gravitational wave data analysiscompute resource at Cardiff. The current facility, recently upgraded, shall provide the UK share of compute resources until completion of O4 data analysis. The richness of science from GW observation is manifest with discoveries now made at a rate of about one per week, so continued participation in computing for data analysis (DA) is critical for the UK contribution.

英国运营计划允许继续参与高级LIGO引力波探测器和相关数据分析。这项工作的继续使英国科学家能够参与全球引力波探测器网络产生的丰富和令人兴奋的科学。该提案有三个工作包（WP）：WP 1-支持LIGO科学合作（LSC）探测器操作。这将使联合王国继续参与高级LIGO探测器的调试、运行、探测器表征和数据分析等活动。WP 2-支持英国提供的硬件（高级LIGO探测器组件）的操作。这提供了所需的现场英国努力，准备和优化新安装的镜子的悬挂纤维，并将镜子焊接到其悬架上，以及相关的现场和非现场支持。该工作包还提供了相关探测器组件的优化和表征。 WP 3-计算基础设施和数据存储。这为英国在卡迪夫的主要引力波数据分析计算资源的维护和运行提供了资金。目前的设施，最近升级，应提供计算资源的英国份额，直到完成O 4数据分析。GW观测的科学丰富性是显而易见的，现在发现的速度约为每周一次，因此继续参与数据分析计算（DA）对英国的贡献至关重要。
