FY17 Safeguards Factsheet for LL16-MagMicro-PD1La
- Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
Magnetic Microcalorimeters (MMCs) are gamma-ray detectors with an energy resolution 10x higher than high-purity germanium detectors. They can improve nuclear data, enable the detection of new isotopes (e.g. Pu-242 of U-236), and increase the accuracy of non-destructive analysis of nuclear materials in cases where Ge detectors are limited by line overlap. MMCs consist of a magnetic sensor operated at temperatures below 50 mK, and they infer gamma-ray energies from the change in magnetization due to the temperature increase after gamma-ray absorption. The goal of this project is to further increase the energy resolution and sensitivity of MMC gamma detectors.
