Research at the Kellogg Radiation Laboratory of the California Institute of Technology includes both experimental research and theoretical research addressing key issues in nuclear physics and related areas of particle physics and high-energy astrophysics. Research topics include neutrino oscillation studies, ultra-cold neutron research, and ultra-high energy cosmic ray studies. Participation by postdoctoral scholars, graduate students and undergraduate students is integrated throughout the program, affording young researchers exceptional opportunities to advance their training and education in these frontier areas of nuclear physics and astrophysics .Neutrino oscillations will be addressed by a new experimental project to study the remaining unknown mixing angle q13 by measuring the disappearance of antineutrinos from a nuclear power plant. During this grant period this new project should begin construction.We will also embark on a new experimental program utilizing novel techniques to produce and study ultra-cold neutrons. These neutrons are converted to very cold temperatures where they can be trapped for long periods of time, enabling very precise measurements of their properties. The first experiment will study the violation of mirror symmetry in the decay of ultra-cold neutrons. We will also perform research and development towards a new experiment to determine the electric dipole moment of the neutron, which should begin construction during this grant period.Theoretical studies related to these experimental efforts are also part of this program.We will continue to maintain operation of the California HIgh school Cosmic ray ObServatory (CHICOS) as a facility to obtain a sample of ultra-high energy cosmic rays and as an outreach program for K-12 teachers and students in the Los Angeles area.

加州理工学院凯洛格辐射实验室的研究包括实验研究和理论研究，解决核物理和粒子物理和高能天体物理相关领域的关键问题。研究课题包括中微子振荡研究、超冷中子研究和超高能宇宙射线研究。博士后学者、研究生和本科生的参与贯穿于整个项目，为年轻的研究人员提供了在核物理和天体物理这些前沿领域推进他们的培训和教育的绝佳机会。中微子振荡将由一个新的实验项目来解决，该项目通过测量核电站中反中微子的消失来研究剩余的未知混合角q13。在拨款期间，这个新项目将开始建设。我们还将开始一个新的实验项目，利用新技术来产生和研究超冷中子。这些中子被转换到非常冷的温度，在那里它们可以被捕获很长一段时间，从而可以非常精确地测量它们的性质。第一个实验将研究超冷中子衰变中镜像对称的破坏。我们还将研究和开发一项新的实验，以确定中子的电偶极矩，该实验将在此拨款期间开始建设。与这些实验工作相关的理论研究也是本计划的一部分。我们将继续维持加州高中宇宙射线天文台（CHICOS）的运作，作为获取超高能量宇宙射线样本的设施，并作为洛杉矶地区K-12教师和学生的外展计划。
