This proposal is for funding of the UK Node of the European ALMA Regional Centre, which will continue to provide the UK ALMA community with direct user support, training and specialized software for experiment design, scheduling, data analysis and astrophysical interpretation. The Atacama Large Millimetre Array (ALMA) is transformational, and is revolutionising astronomy in the millimetre and sub-millimetre band with angular resolution, sensitivity, imaging quality and spectral coverage orders of magnitude beyond what available only a few years ago. The range of scientific applications is very broad, stretching from comets to cosmology, but ALMA's key strength is the detailed imaging of the processes of star and planet formation in our own galaxy and in the Universe at large, directly addressing many of the key themes of STFC's astronomical vision. ALMA operates at a very dry high (5000m) site in the Atacama Desert of northern Chile, close to the edge of the radio atmospheric window. The telescope has been very successful in automating much of the data processing for standard modes of operation, producing acceptable images approaching publishable quality for astronomers who are not experts in interferometry. However, for full exploitation of science extraction from advanced imaging many users require and appreciate additional support from skilled interferometry experts. In addition, ALMA operations can at times be challenging, especially non-standard modes such as for ultra-high angular resolution imaging with physically extended telescope configurations in the shortest wavelength bands. The operating plan for ALMA devolves all user interaction and support to three regional centres (ARCs) in US, Japan and Europe. The European model is a distributed one, with a central coordinating Node based at ESO in Garching and all face-to-face user support and more advanced data analysis facilities and enhanced imaging provided by a network of individual Nodes funded at the national level. In addition to the ESO Node there a 7 regional Nodes across Europe with UK ALMA user support being provided by the UK Node housed at the University of Manchester. The UK Node provides user support tailored to the requirements of individual UK ALMA users to assist in maximising their scientific return on ALMA programmes. It also provides support to all UK ALMA users for the complete set of elements for their ALMA science programmes from proposal preparation through quality assurance assessment of their data (especially for those programmes involving non-standard operational modes), to advanced imaging and maximisation of science extraction. The Node also provides regular workshops to both enhance science extraction through advanced data processing/imaging, and ensures the distribution of information regarding new ALMA developments and capabilities. The UK Node also provides IT hardware (computing power and data storage) to simultaneously support several UK-led ALMA projects (through both face-to-face and remote support); including the hosting of large ALMA programmes and programmes for international consortia. The UK Node is involved in the development of new and enhanced software tools to assist UK ALMA users in their project planning and execution - for both new programmes and archival access projects. UK Node personnel participate in ALMA development and EOC (Extension and Optimisation of Capabilities) commissioning programmes to utilise existing UK Node skills to deliver such programmes, and in addition provide enhanced support for UK ALMA users with regard to new ALMA developments.The UK ALMA user community has benefitted from the expert support provided by the UK Node and has grown to be a major user of ALMA. In the last 3 years of ALMA operations (Cycles 4-6) successful UK ALMA users have been awarded 26% of all the approved European time.

该建议是为欧洲ALMA地区中心的英国节点提供资金，该中心将继续为英国Alma社区提供直接的用户支持，培训和专业软件，用于实验设计，调度，数据分析和天体物理学解释。 Atacama大毫米阵列（ALMA）是变换的，并且在毫米和亚毫米频带中彻底改变了天文学，其角度分辨率，灵敏度，成像质量和光谱覆盖率范围超出了几年前可用的数量级。科学应用的范围非常广泛，从彗星到宇宙学都延伸，但是Alma的关键优势是对我们自己的银河系中恒星和行星形成过程的详细成像，在整个宇宙中，直接解决了STFC天文学视觉的许多关键主题。 Alma在智利北部Atacama沙漠的一个非常干燥的高（5000m）地点运营，靠近无线电大气窗的边缘。该望远镜在为标准操作模式的大部分数据处理中自动化，为不是干涉率专家的天文学家的可接受图像而自动化的大部分数据处理。但是，要全面利用科学从高级成像中提取，许多用户需要并感谢熟练的干涉法专家的额外支持。此外，ALMA操作有时可能具有挑战性，尤其是非标准模式，例如以最短的波长频段进行物理扩展的望远镜配置，具有超高的角度分辨率成像。 ALMA的运营计划将所有用户互动和支持都推向了美国，日本和欧洲的三个区域中心（ARC）。欧洲模型是分布式模型，其中央协调节点位于ESO的Garching和所有面对面的用户支持以及更高级的数据分析设施以及由国家级别资助的单个节点网络提供的增强成像。除了ESO节点外，欧洲还有7个区域节点，由英国ALMA用户支持由曼彻斯特大学的英国节点提供。英国节点提供了针对单个英国Alma用户要求的用户支持，以帮助他们最大程度地提高其ALMA计划的科学回报。它还为所有英国ALMA用户提供支持，以完成其ALMA科学计划的完整要素，从提案准备到其数据的质量保证评估（尤其是对于那些涉及非标准操作模式的计划），再到对科学提取的高级成像和最大化。该节点还提供定期的研讨会，既可以通过先进的数据处理/成像来增强科学提取，并确保有关新的Alma开发和能力的信息分布。英国节点还提供了IT硬件（计算能力和数据存储），以同时支持英国领导的几个ALMA项目（通过面对面和远程支持）；包括举办大型ALMA计划和国际财团计划。英国节点参与了新的和增强的软件工具的开发，以帮助英国ALMA用户进行项目计划和执行 - 用于新程序和档案访问项目。英国节点人员参与ALMA开发和EOC（功能的扩展和优化）调试计划，以利用现有的英国节点技能来提供此类计划，此外，为英国ALMA用户提供了增强的支持。在新的ALMA开发方面，英国ALMA用户社区也从英国节点提供的专家支持中受益，并且已经成长为Alma的主要用户。在过去的三年中，ALMA运营（周期4-6）成功的英国Alma用户被授予了所有批准的欧洲时间的26％。
