Abstract
75308-Fundamental research in nuclear physics, such as the search for the neutron electric dipole moment (EDM), requires advances in detector systems and instrumentation. In particular, advanced detector systems are needed to enable precise experimental measurements of the magnetization of polarized nuclei in noisy environments. This project will develop a novel magnetic detector system, based on ultrasensitive superconducting quantum interference device (SQUID) sensors, that is sensitive to magnetic field gradients and discriminates against uniform magnetic fields and ambient noise sources. In Phase I, the initial designs of the superconducting quantum interference device detectors will be developed and the first prototypes will be fabricated. Suitable packaging for these detectors, which will not compromise intrinsic detector performance, will be designed. The prototype detectors will be characterized and the efficacy of the proposed electronic compensation scheme to improve noise rejection will be demonstrated. Commercial Applications and Other Benefits as described by the awardee: The advanced SQUID magnetic detectors, with novel electronic compensation to improve ambient noise rejection, should be attractive not only for nuclear physics research but also for such commercial biomedical imaging applications as magnetocardiography, which is receiving growing interest as a clinical tool to detect and diagnose heart disease.
