Study of spin structure of hadrons using polarized photons

在2007-2010年期间，我们的研究将集中在光生实验中使用的CLAS探测器系统在杰斐逊实验室的大厅B的偏振观测。作为FROST计划（使用偏振光子束和冻结自旋目标）和CLAS的HD目标计划（与BNL的偏振目标组合作）的领先机构，我们预计运行准备，数据采集，数据校准和重建将是这些年来我们努力的重要组成部分。此外，还将完成对欧米茄电和光产生以及K 0光产生的持续分析。我们将继续为杰斐逊实验室B厅的光子束实验提供必要的服务工作，特别是关于运行标记描迹仪和相干韧致辐射设施。此外，我们的软件支持在CLAS中的带电粒子跟踪仍然是CLAS数据分析的关键。在这段时间结束时，我们在JLab新的D厅的GluEx实验工作将开始，需要更多的时间。我们的责任是建立光子束线设备是与美国分担。康涅狄格州和格拉斯哥大学;我们将继续我们的研发工作，并期望在2010年开始建造标记波迹示波器。通过所有这些工作，我们为研究生和博士后研究助理提供培训和专业经验。

Our research during 2007-2010 will focus on polarization observables from photoproduction experiments using the CLAS detector system in Hall B of Jefferson Lab. As a leading institution in both the FROST program (using polarized photon beams and a frozen-spin target) and the HD-target program at CLAS (in collaboration with the polarized target group at BNL), we expect that run preparation, data taking, data calibration and reconstruction will be a large part of our effort during these years. In addition, ongoing analyses of omega electro- and photoproduction and K0 photoproduction will be completed. We will continue to perform essential service work for photon beam experiments in Hall B at Jefferson Lab, especially with regard to running the tagging hodoscope and the coherent bremsstrahlung facility. Moreover, our software support concerning charged particle tracking in CLAS continues to be crucial for any analysis of CLAS data.Toward the end of this period, our work for the GluEx experiment in the new Hall D at JLab will begin taking more of our time. Our responsibility to build the photon beam line equipment is shared with U. Connecticut and Glasgow U.; we continue our R&D efforts and expect construction of the tagging hodoscope to start in 2010. Through all of this work, we provide training and professional experience to graduate students and a postdoctoral research associate.
