该申请寻求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（EPSRC参考：RE-10-0005-EPSRC-STEM）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的奖金将从其他地方获得总计129.3万英镑的捐款。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、格拉斯哥大学和利物浦大学）组成的联盟管理，由利兹大学的里克·布赖德森教授领导。它以STFC Daresbury实验室的SuperSTEM设施为基础（www.superstem.org），但也可以访问财团大学站点和合作伙伴站点（目前是剑桥，谢菲尔德，华威和约克）的互补先进仪器。上一次EPSRC评审小组（2005年）将SuperSTEM设施评为“国际优秀”。自本次评审以来，研究影响的亮点包括：-共有104篇期刊出版物与用户（9篇自然组/PRL）-自2007年以来32次邀请演讲和23次会议贡献-原子分辨率EELS映射的首次演示-对2010年诺贝尔奖获奖的石墨烯工作的重大贡献国家设施在最近一轮的中期用户设施招标中被EPSRC授予450万英镑。该设施的招标要求由用户社区的需求声明和随后的城镇会议确定。SuperSTEM和联盟/合作大学的设备组合能够满足许多（但不是全部）招标要求。450万英镑的招标预算上限，加上对人员配备水平的要求，意味着资本预算不足以购买SuperSTEM3。作为备选方案，预算中有1,103,000英镑用于升级SuperSTEM2，这是当前SuperSTEM仪器中更现代化的设备。如下所述，这远非一个令人满意的选择。新仪器SuperSTEM3将被安置在超级stem实验室一个专门建造的“吊舱”中。并将确保国家设施、其用户以及英国保持在纠正畸变的STEM研究和开发的前沿。在一个完全集成的最先进的仪器中组合单色/Cc校正器将开辟新的研究领域。它将充分利用STEM成像和原子分辨率光谱的空间分辨率提高的优势，降低研究许多纳米材料所需的低加速电压。电子能谱的能量分辨率的提高将开辟新的研究领域，包括振动能谱的潜力。

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.
