This award supports research in Elementary Particle Physics by Dr. Peter T. Timbie, a Presidential Young Investigator, Brown University. The aim of the research is to develop and employ new types of sensitive cryogenic detectors of infrared and microwave background radiation, the relic from the Big Bang. This radiation tells us the temperature and distribution of matter in the early phase of the universe. Both bolometer detectors cooled at very low temperature and superconducting tunnel junction will be used to build a small array for the observation of this microwave background radiation. These detectors will also be used to detect particles that interact only weakly with matter, such as the particle which may form the "dark matter" of the universe or neutrinos.

该奖项支持布朗大学总统青年研究员彼得·T·蒂姆比博士在基本粒子物理学方面的研究。这项研究的目的是开发和应用新型灵敏的红外和微波背景辐射低温探测器，这是大爆炸的遗迹。这种辐射告诉我们宇宙早期的温度和物质的分布。在极低温度下冷却的测辐射热计探测器和超导隧道结将被用来建造一个小阵列来观测这种微波背景辐射。这些探测器还将用于探测仅与物质弱相互作用的粒子，例如可能形成宇宙或中微子的“暗物质”的粒子。
