This application seeks an EPSRC Capital Grant of £1,079,600 towards the shortfall of £2,372,600 required to install a world leading aberration-corrected & monochromated dedicated scanning transmission electron microscope (SuperSTEM3) at the EPSRC National Facility for Scanning Transmission Electron-Microscopy (STEM) (EPSRC Reference: RE-10-0005-EPSRC-STEM). The EPSRC award will be matched by contributions from elsewhere totalling £1,293,000. As part of the National Facility, SuperSTEM3 will support many users from the UK and elsewhere and have a high utilisation factor.The National Facility is run by a consortium of five Universities (Leeds, Oxford, Manchester, Glasgow and Liverpool) and is led by Prof Rik Brydson of Leeds. It is based around the SuperSTEM facility at STFC Daresbury Laboratories (www.superstem.org) but also provides access to complementary advanced instrumentation at Consortium University sites and Partner sites (currently Cambridge, Sheffield, Warwick and York). The last EPSRC review panel (2005) rated the SuperSTEM facility 'internationally outstanding'. Highlights of research impact since this review include:- a total of 104 journal publications with users (9 Nature group/PRL)- 32 invited talks and 23 conference contributions since 2007- the first demonstration of atomically resolved EELS mapping - a significant contribution to 2010 Nobel prize winning work on graphene The National Facility was awarded £4.5M by EPSRC in the recent round of tenders for mid-range user facilities. The requirements of the tender for this facility were determined by a Statement of Need from the user community and a subsequent Town Meeting. The combination of equipment at SuperSTEM and the Consortium/Partner Universities is able to meet many, but not all, of the tender requirements. The cap £4.5M on the tender budget combined with the requirements on staffing levels meant that the capital budget was insufficient to purchase SuperSTEM3. As a fall-back position, £1,103,000 of the budget was allocated to upgrading SuperSTEM2, the more modern of the current SuperSTEM instruments. As detailed below, this is far from a satisfactory option. The new instrument, SuperSTEM3, will be housed in a new purpose-built "pod" at the SuperSTEM Lab. and will ensure the National Facility, its users and hence the UK remains at the forefront of aberration corrected STEM research and development. The combined monochromator/Cc corrector in a fully integrated state-of-the-art instrument will open up new areas for study. It will allow the full benefits of improved spatial resolution for STEM imaging and atomic resolution spectroscopy down to the low accelerating voltages necessary to study many nanomaterials. The improved energy resolution for electron spectrometry will open up new areas of study including the potential for vibrational spectroscopy.

本申请寻求1,079,600 GB的EPSRC资本拨款，以弥补在EPSRC国家扫描透射电子显微镜(STEM)设施(EPSRC参考：RE-10-0005-EPSRC-STEM)安装世界领先的象差校正和单色专用扫描透射电子显微镜(SuperSTEM3)所需的2,372,600 GB的缺口。EPSRC的奖励将与来自其他地方的捐款相匹配，总额为1,293,000 GB。作为国家设施的一部分，SuperSTEM3将支持来自英国和其他地方的许多用户，并具有高利用率。国家设施由五所大学(利兹、牛津、曼彻斯特、格拉斯哥和利物浦)组成的财团运营，由利兹的Rik Brydson教授领导。它以STFC达雷斯伯里实验室的SuperSTEM设施(www.Superstem.org)为基础，还提供访问Consortium大学网站和合作伙伴网站(目前是剑桥、谢菲尔德、华威和约克)的补充先进仪器的途径。上一次EPSRC审查小组(2005)将SuperSTEM工厂评为“国际优秀”。自这次审查以来，研究影响的亮点包括：-共有104篇期刊出版物与用户(9个自然组/PRL)-自2007年以来32次受邀的演讲和23篇会议稿件-原子分辨EELS图谱的首次演示-对2010年诺贝尔奖获奖工作的重大贡献石墨烯在最近一轮中端用户设施招标中，国家设施被EPSRC授予450万GB。这一设施的招标要求是由用户社区的需求声明和随后的市政会议确定的。SuperSTEM和联盟/伙伴大学的设备组合能够满足许多但不是所有的投标要求。招标预算的上限为450万GB，再加上对人员配备水平的要求，这意味着资本预算不足以购买SuperSTEM3。作为后备，预算中的1,103,000 GB被分配给升级SuperSTEM2，这是目前SuperSTEM仪器中更现代化的。如下所述，这远不是一个令人满意的选择。这台名为SuperSTEM3的新仪器将被安置在SuperSTEM实验室专门建造的新“吊舱”中。并将确保国家设施、其用户以及英国保持在纠偏STEM研究和开发的前沿。将单色仪/CC校正仪结合在一个完全集成的最先进的仪器中，将为研究开辟新的领域。它将使STEM成像和原子分辨率光谱分析的空间分辨率提高的全部好处降至研究许多纳米材料所需的低加速电压。电子光谱学能量分辨率的提高将开辟新的研究领域，包括振动光谱学的潜力。
