This research is on the development of sensors for acoustic detection of low energy deposition in ultra-cold silicon crystals. The investigation will focus on possible methods for the detection of the phonons (sound quanta) produced when energy is absorbed in the crystal. The distribution of these phonons at the crystal surface yields information on the location and amount of energy deposit. If successfully developed, the acoustic sensors and associated silicon crystals could be used to detect neutrinos and other neutral, weakly interacting particles. This would allow sensitive tests of the energetics of the sun, and the possible existence of "dark matter" in the universe.

本研究是关于超冷硅单晶中低能沉积声学检测传感器的研制。这项研究将集中在探测晶体中吸收能量时产生的声子(声量子)的可能方法。这些声子在晶体表面的分布提供了关于能量沉积位置和数量的信息。如果研制成功，声波传感器和相关的硅晶体可以用来探测中微子和其他中性的、弱相互作用的粒子。这将允许对太阳的能量学进行敏感的测试，以及宇宙中可能存在的“暗物质”。
