The Oregon experimental relativity group plans to continue its vigorous efforts within the LIGO Scientific Collaboration (LSC) to search for burst sources of gravitational radiation (GWBs). The Oregon experimental relativity group will continue to focus a significant fraction of its effort on the identification and amelioration of noise sources in the LIGO interferometers, as a prerequisite to the realization of a scientific discovery. The program involves two complementary areas of activity in GWB science within the LSC: (1) data analysis and (2) detector characterization and improvement. In the area of data analysis, the search for GWBs produced in association with gamma-ray bursts (GRBs) in the initial LIGO science runs S2, S3, and S4 will be completed. Then the analysis will be refined for the long science run S5, and beyond. A search for gravitational radiation emission from supernovae, initially based on a template matching technique, will also be advanced. The detector characterization and improvement effort will continue to focus on environmental influences. Work will continue on identifying and reducing environmental influences in order to improveinterferometer sensitivity, and to decrease false detection rates. Efforts will extend beyond these two primary areas, and have important contributions to all LIGO searches and the success of Advanced LIGO.This research contributes significantly to society, due to its profound, fundamental nature, and the opportunities which are associated to enable broad participation in the scientific enterprise. The discovery of gravitational radiation would be a major achievement in advancing the applications of Einstein's General Theory of Relativity, and initiate a new age of discovery and understanding. Publications of the scientific results would mark a great moment of human enlightenment regarding the nature of the universe. The Oregon group makes a special effort to broaden the impact of this work by integrating the most advanced, technical aspects with outreach activities. These include undergraduate participation in the group's research, summer research programs for talented high school students, work with Oregon high school teachers to bring the research experience into thehigh school (part of the Quark Net program), and speaking engagements to community groups.

俄勒冈州实验相对性小组计划在Ligo Scientific Collaporation（LSC）中继续努力，以寻找引力辐射的爆发来源（GWBS）。 俄勒冈实验相对性组将继续将其努力的很大一部分集中在LIGO干涉仪中噪声源的识别和改善上，这是实现科学发现的先决条件。该计划涉及LSC中GWB科学活动中的两个互补领域：（1）数据分析和（2）检测器的表征和改进。在数据分析领域，将完成与伽马射线爆发（GRB）相关的GWB的搜索，将完成S2，S3和S4。 然后，将对长期的科学运行S5及以后进行分析。最初基于模板匹配技术的超新星的重力辐射发射的搜索也将是先进的。 探测器的表征和改进工作将继续关注环境影响。为了提高未介入仪的敏感性并降低错误检测率，工作将继续识别和减少环境影响。 努力将超越这两个主要领域，并为所有Ligo搜索和先进的Ligo的成功做出重要贡献。这项研究对社会产生了很大的贡献，这是由于其深刻的，基本的性质，以及与能够广泛参与科学企业相关的机会。 引力辐射的发现将是推进爱因斯坦一般相对论的应用，并启动新的发现和理解时代的主要成就。 科学成果的出版物将标志着人类关于宇宙本质的伟大时刻。 俄勒冈集团通过将最先进的技术方面与外展活动相结合，以特别努力扩大这项工作的影响。其中包括本科生的研究，为才华横溢的高中学生提供的夏季研究计划，与俄勒冈州高中教师合作，将研究经验带入高校（Quark Net计划的一部分）以及向社区团体进行演讲。
