Microcalorimeter Magnetic Sensor Geometries Using Superconducting Elements

摘要

We describe a numerical code developed to estimate performance of magnetic microcalorimeter configurations, including superconducting elements and SQUID characteristics. We present results of a preliminary design analysis showing that composite sensors with both superconducting and paramagnetic elements should realize substantial gains in magnetic flux signal per magnetization change of the paramagnet, compared to sensors containing only paramagnet.
