This proposal requests funds to support a research team of graduate students and undergraduates to work on several of challenging measurements.  My philosophy is to identify open questions that can be answered with improved and innovative measurement techniques.  For example by setting up ultra low temperature specific heat measurements we have identified previously undetected phase transitions in frustrated magnetic materials.  Another example is developing a new photon detector that can be multiplexed to large number of pixel arrays and can be optimized for a large range of energy (from sub-mm to x-ray). These detectors (Kinetic inductance detectors) are now being developed for state-of-the-art telescope cameras but can be adapted to other applications such as x-ray detectors for medical research.  My group works on superconducting quantum interference devices (SQUIDS). These are the most sensitive magnetic field sensors, with this we customize measurements to detect subtle magnetic properties of novel materials. We are studying the magnetic properties of a fascinating and complex systems of frustrated magnetic materials that can be candidates for new classes of magnetic state (quantum spin liquids). In all these projects we collaborate with experts, either theorists that specialize in magnetic materials, crystal growers and neutron scatterers that have complimentary measurements and interests, or astrophysicists that have a different and complimentary background.

该提案要求资金支持一个由研究生和本科生组成的研究团队进行几项具有挑战性的测量。 我的哲学是找出可以通过改进和创新的测量技术来回答的开放性问题。例如，通过建立超低温比热测量，我们发现了以前未检测到的受挫折磁性材料的相变。另一个例子是开发一种新的光子探测器，可以多路复用到大量的像素阵列，并可以针对大范围的能量进行优化（从亚毫米到X射线）。这些探测器（动态电感探测器）目前正在为最先进的望远镜相机开发，但也可以适用于其他应用，如医学研究的X射线探测器。 我的团队致力于超导量子干涉设备（SQUIDS）。这些都是最敏感的磁场传感器，我们定制测量，以检测新材料的微妙磁特性。我们正在研究一个迷人的和复杂的受挫折的磁性材料系统的磁特性，可以成为新类别的磁状态（量子自旋液体）的候选者。在所有这些项目中，我们与专家合作，无论是专门研究磁性材料的理论家，晶体生长者和中子散射者，都有互补的测量和兴趣，或者是具有不同和互补背景的天体物理学家。
