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.

这项建议是为欧洲阿尔马区域中心的英国节点提供资金，该节点将继续向英国阿尔马社区提供直接的用户支持、培训和用于实验设计、时间安排、数据分析和天体物理解释的专门软件。阿塔卡马大型毫米波阵列（阿尔马）具有变革性，正在彻底改变毫米和亚毫米波段的天文学，其角分辨率、灵敏度、成像质量和光谱覆盖范围超出了几年前的数量级。科学应用的范围非常广泛，从彗星到宇宙学，但阿尔马的主要优势是对我们自己的星系和宇宙中的星星和行星形成过程的详细成像，直接解决了STFC天文学愿景的许多关键主题。阿尔马在智利北方的阿塔卡马沙漠一个非常干燥的高地（5000米）上工作，靠近无线电大气窗口的边缘。该望远镜在标准操作模式下的大部分数据处理自动化方面非常成功，为非干涉测量专家的天文学家提供了可接受的图像，接近可重复的质量。然而，为了充分利用先进成像的科学提取，许多用户需要并感谢熟练的干涉测量专家的额外支持。此外，阿尔马操作有时可能具有挑战性，特别是非标准模式，例如在最短波长带中使用物理扩展望远镜配置的超高角分辨率成像。阿尔马的业务计划将所有用户互动和支持移交给美国、日本和欧洲的三个区域中心。欧洲的模式是分布式的，有一个设在Garching的欧洲南方天文台的中央协调节点，所有面对面的用户支持和更先进的数据分析设施，以及由国家一级资助的单个节点网络提供的增强型成像。除了ESO节点外，还有7个区域节点遍布欧洲，英国阿尔马用户支持由曼彻斯特大学的英国节点提供。联合王国节点根据联合王国阿尔马用户的具体要求提供用户支持，以帮助他们最大限度地提高阿尔马方案的科学回报。它还向所有英国阿尔马用户提供支持，为其阿尔马科学计划提供全套要素，从提案准备到数据质量保证评估（特别是涉及非标准操作模式的计划），再到先进的成像和最大限度地提高科学提取。该节点还定期举办讲习班，通过先进的数据处理/成像来加强科学提取，并确保传播有关阿尔马新发展和能力的信息。联合王国节点还提供信息技术硬件（计算能力和数据存储），以同时支持联合王国领导的几个阿尔马项目（通过面对面和远程支持）;包括主办大型阿尔马方案和国际财团方案。联合王国节点参与开发新的和增强的软件工具，以协助联合王国阿尔马用户进行新方案和档案查阅项目的项目规划和执行。英国节点人员参与阿尔马开发和EOC（扩展和优化能力）调试计划，以利用现有的英国节点技能来交付此类计划，此外，还为英国阿尔马用户提供有关新阿尔马开发的增强支持。英国阿尔马用户社区受益于英国节点提供的专家支持，并已发展成为阿尔马的主要用户。在阿尔马运行的最后3年（周期4-6）中，成功的英国阿尔马用户获得了所有批准的欧洲时间的26%。
