Upgrade of X8 Apex II Diffractometer with Mo IMS Microfocus Source/Optics

此NSERC RTI应用程序请求支持升级布罗克大学已有12年历史的Bruker Apex II单晶X射线衍射仪，该衍射仪最初是在2004年通过CFI新机遇计划购买的。这次升级包括三个组件，一个高压IG250，19英寸发电机，以取代六个月前报废的原始发电机，将原来的钼密封管升级为钼微焦点X射线源，这是加拿大仪器上安装的第一个此类设备，对所有更换的部件提供3年保修，并计划在合同期内进行紧急和/或维护访问，以保持仪器全天候运行。单晶X射线衍射对布罗克的大多数化学教员来说至关重要。这是一种确定分子固体中原子之间连接性的技术。它被不同的研究人员使用，以确认新化合物的成功合成和/或帮助了解材料的化学反应和物理性质。在布罗克，获得工作中的X射线衍射仪对申请者的研究计划是绝对关键的，也是支持其他几个较小用户研究的重要技术。这一升级将为布罗克研究人员提供更高强度的X射线束，使更小、更弱的衍射率晶体能够被测量，并减少收集数据所需的时间，以便可以筛选和测量更多样品，使仪器更高效、更具成本效益。来自几个小组的本科生、研究生和博士后研究人员将接受关于这种仪器的实践培训。这笔资金将确保布罗克的教职员工继续使用最先进的仪器设备，使他们能够维持世界级的研究计划和培训制度，以培训下一代高素质的加拿大研究人员，这些研究人员将对加拿大经济的高科技和传统制造业产生影响。

This NSERC RTI application requests support to upgrade the 12 year old Bruker Apex II single crystal X-ray diffractometer at Brock University, originally purchased through the CFI New Opportunities program in 2004. This upgrade comprises of three components, a high voltage IG250, 19 inch generator to replace the original generator that reached the end of its lifetime six months ago, an upgrade of the original Mo sealed tube to a Mo Microfocus X-ray source, the first of its kind installed on instrumentation within Canada and a 3 year warranty on all replaced parts plus an emergency and/or maintenance visit scheduled for within the contract period to keep the instrumentation running 24/7. Single crystal X-ray diffraction is crucial to the majority of chemistry faculty at Brock. It is THE technique which determines the connectivity between atoms in a molecular solid. It is used by a diverse range of researchers in order to confirm the successful synthesis of a new compound and/or to help understand the chemical reactivity and physical properties of a material. At Brock access to a working X-ray diffractometer is absolutely crucial to the research programs of the applicants and an important technique underpinning the research of several additional minor users. This upgrade will provide Brock researchers with a higher intensity X-ray beam enabling smaller, more weakly diffracting crystals to be measured and reduce the time taken to collect data so that more samples can be screened and measured, making the instrumentation more efficient and cost effective. Undergraduate, graduate and postdoctoral researchers from several groups will receive hands-on training on this instrumentation. This funding will ensure that Brock faculty continue to have access to state-of the-art instrumentation, enabling them to maintain world class research programs and training regimes to train the next generation of high calibre Canadian researchers that will impact both the high technology and traditional manufacturing sectors of the Canadian economy.
