Nuclear Physics Equipment 2015

本申请中寻求的设备将加强由核物理综合补助金支持的研究方案。该奖项是去年颁发的。我们为进一步发展该方案选择了两个机会：位于德国美因茨的Mami设施的格拉斯哥光子标签光谱仪的升级焦平面探测器；英国对弗吉尼亚州纽波特纽波特纽斯杰斐逊实验室(JLab)C厅的新实验工作的贡献。焦平面探测器需要升级，因为探测器组件随着时间的推移逐渐退化。这次翻新还将导致速率能力增加5-10倍，这将允许一个更雄心勃勃的强子结构和光谱学测量计划，这些主题在上一轮拨款中得到了高度评价。C厅实验提案得到了国际JLab PAC的高度评价和批准，汉密尔顿博士作为该提案的发言人领导了这项工作。该计划已经从NSF重大研究计划(MRI)赠款中吸引了100万美元的资金，我们的请求是提供电磁量热计的冷却系统，以及消除低能带电粒子背景所需的偏转磁铁的一部分。

The equipment sought in this request will enhance the programme of research that has been supported with the Nuclear Physics Consolidate Grant,. which was awarded last year. We have selected two opportunities for developing the programme further: an upgraded focal plane detector for the Glasgow Photon Tagging spectrometer, located at the MAMI facility in Mainz, Germany; a UK contribution to a new experimental effort in Hall C, Jefferson Lab in Newport News, Virginia (JLab).The focal plane detector is in need of an upgrade, since the detector components are gradually deteriorating over time. This refurbishment will also result in a factor of 5-10 increase in rate capability, which will allow a more ambitious programme of measurements in hadron structure and spectroscopy, themes that were highly rated in the previous grants round.The Hall C experimental proposal has been highly rated and approved by the international JLab PAC, and Dr Hamilton is leading this effort as a spokesperson of the proposal. This programme has already attracted funding of $1million from an NSF Major Research Initiative (MRI) grant, and our request is to provide the cooling system of an electromagnetic calorimeter, as well as part of a deflection magnet that is required to remove low-energy charged particle background.
