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.

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). EPSRC奖将与其他地方的总计1,293,000英镑的捐款相匹配。作为国家设施的一部分，SuperStem3将为来自英国和其他地方的许多用户提供支持，并具有很高的利用因素。该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）组成的财团经营，并由利兹的里德森教授Rik Brydson教授领导。它基于STFC Daesbury Laboratories（www.superstem.org）的Superstem设施，但也提供了在财团和合作伙伴站点（目前剑桥，谢菲尔德，沃里克和约克）的完整高级仪器的访问权限。最后一部EPSRC评论小组（2005）将超级巨星设施评为“国际杰出”。 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.招标对该设施的要求取决于用户社区的需求声明和随后的城镇会议。超级巨星和财团/合作伙伴大学设备的组合能够满足许多但不是全部招标要求。票价预算的450万英镑以及人员配备水平的要求意味着资本预算不足以购买SuperStem3。作为后备职位，预算的1,103,000英镑分配给了升级Superstem2，这是当前超级巨星仪器中更现代的超级巨星。如下所述，这远非满意度。新乐器Superstem3将在Superstem Lab的新型专用“ Pod”中安装。并将确保国家设施，其用户，因此英国仍然处于畸变纠正的STEM研发的最前沿。完全集成的最新仪器中的单色组合/CC校正器将为研究开放。这将允许改善空间分辨率的茎成像和原子分辨率光谱的全部好处，直到研究许多纳米材料所需的低加速度电压。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。
