The proposed AMRR system will enable NASA to carry out future space astronomy missions that use cryogenic infrared, gamma ray, and X ray detectors. These detectors need to operate at temperatures in the range of 4 K to below 1 K to reduce the thermal emission of the detectors themselves and to achieve high sensitivity and resolution. The vibration-free, lightweight AMRR can provide efficient cooling for these missions at the required temperature ranges. The fabrication technologies developed for the lightweight superconducting magnets can also be applied to the fabrication of advanced magnets for multistage active demagnetization refrigerators (ADRs), particle accelerators, and portable MRIs.
Military applications for the proposed magnetic cooler include cooling systems on space-based surveillance, missile detection, and missile tracking systems. Scientific applications include cooling systems for material microanalysis using X ray microcalorimeter spectrometers, superconducting radio frequency cavities, superconducting cavities, and superconducting digital electronics.
