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 EPSRC 资本拨款 1,079,600 英镑，以弥补在 EPSRC 国家扫描透射电子显微镜 (STEM) 设施安装世界领先的像差校正和单色专用扫描透射电子显微镜 (SuperSTEM3) 所需的 2,372,600 英镑的缺口（ EPSRC 参考号：RE-10-0005-EPSRC-STEM)。来自其他地方的捐款总计 1,293,000 英镑 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，并且具有很高的利用率。国家设施由五所大学（利兹大学、牛津大学、曼彻斯特大学、格拉斯哥大学）组成的联盟运营。该项目由利兹大学的 Rik Brydson 教授领导，以 STFC Daresbury 实验室的 SuperSTEM 设施为基础。 (www.superstem.org)，同时还提供联盟大学站点和合作伙伴站点（目前为剑桥、谢菲尔德、沃里克和约克）的补充先进仪器。最后的 EPSRC 审查小组（2005 年）将 SuperSTEM 设施评为“国际杰出”。自本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）- 自此以来 32 次受邀演讲和 23 次会议贡献2007 年 - 原子分辨 EELS 测绘的首次演示 - 对 2010 年诺贝尔奖石墨烯工作的重大贡献 在最近一轮中档用户设施招标中，国家设施获得了 EPSRC 450 万英镑的资助。该设施的建设是根据用户社区的需求声明和随后的城镇会议确定的。SuperSTEM 和联盟/合作大学的设备组合能够满足许多需求，但不能满足。招标预算上限为 450 万英镑，加上人员配备水平的要求，意味着资本预算不足以购买 SuperSTEM3。 SuperSTEM2 是当前 SuperSTEM 仪器中更现代的产品，如下所述，这远非令人满意的选择。新仪器 SuperSTEM3 将安装在新的专用“吊舱”中。 SuperSTEM 实验室将确保国家设施、其用户以及英国始终处于像差校正 STEM 研究和开发的前沿。完全集成的最先进仪器中的组合单色仪/Cc 校正器将开辟新的领域。它将充分发挥 STEM 成像和原子分辨率光谱学的空间分辨率提高到研究许多纳米材料所需的低加速电压的优势。电子光谱学的能量分辨率提高将开辟新的领域。研究的重点包括振动光谱学的潜力。
