University of Leeds-Equipment Account

该申请寻求EPSRC资本补助金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奖将与其他地方的捐款相匹配，总额为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，并具有很高的利用率。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）组成的联盟运营，由利兹的Rik Brydson教授领导。它基于STFC达雷斯伯里实验室（www.example.com）的SuperSTEM设施，但也提供了在联盟大学站点和合作伙伴站点（目前剑桥，谢菲尔德，沃里克和约克）的补充先进仪器的访问。上一次EPSRC审查小组（2005年）将SuperSTEM设施评为“国际杰出”。自这次审查以来，研究影响的亮点包括：-共有104个期刊出版物与用户（9个自然组/PRL）-自2007年以来的32个邀请演讲和23个会议贡献-原子分辨EELS映射的首次演示-对2010年诺贝尔奖获奖石墨烯工作的重大贡献国家设施在最近一轮的中档用户设施招标中获得EPSRC 450万英镑。该设施的招标要求是由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但不是全部的投标要求。450万英镑的投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。作为后备，预算中的1，103，000英镑用于升级SuperSTEM 2，这是当前SuperSTEM仪器中更现代的一种。如下文所述，这远远不是一个令人满意的选择。新仪器SuperSTEM 3将被安置在SuperSTEM实验室的一个新的专用“吊舱”中。并将确保国家设施，其用户，因此英国仍然处于畸变校正STEM研究和开发的最前沿。在一个完全集成的国家的最先进的仪器组合单色器/Cc校正器将开辟新的研究领域。它将使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。改进的电子光谱能量分辨率将开辟新的研究领域，包括振动光谱的潜力。

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.
