SGER: Experimental Investigation of Observing Techniques Proposed for the B-Machine

该项目由探索性研究计划的小额拨款支持，旨在测试偏振调制方案，使用安装在白山巴克罗夫特设施的工作原型。这个测试是必要的，因为担心可能的系统偏差和方法的其他缺点。未来的目标是在北半球和南半球的多个地点部署大量望远镜阵列，以测量宇宙微波背景（CMB）偏振各向异性中的B模式，或旋度模式。开发和测试这门重要科学的多种方法是很重要的，这个适度的试验将引导未来在CMB研究方面的大规模努力。该组织在让学生参与实验物理学和观测天体物理学方面有着良好的记录，这对所有人都有好处，并将教育和推广到高中和社区大学，作为他们宇宙学研究的内在组成部分。

AST-0545405LubinThis project, supported under the Small Grant for Exploratory Research program, is intended to test a polarization modulation scheme, using a working prototype installed at the White Mountain Barcroft facility. This test is necessary, because of concerns about possible systematic biases and other shortcomings of the method. The future intent is a large deployment of arrays of telescopes to multiple sites in the northern and southern hemispheres to measure what are called B, or curl, modes in the polarization anisotropy of the Cosmic Microwave Background (CMB). It is important to develop and test multiple approaches to this important science, and this modest trial will steer future large efforts in CMB research.The group has a strong record of involving students with experimental physics and observational astrophysics, to the benefit of all, and includes education and outreach to high schools and community colleges as an intrinsic part of their cosmological research.
