Abstract

B-MINE is a concept for a balloon mission designed to probe the deepest regions of a supernova explosion by detecting ⁴⁴Ti emission at 68 keV with spatial and spectral resolutions that are sufficient to determine the extent and velocity distribution of the ⁴⁴Ti emitting region. The payload introduces the concept of focusing optics and microcalorimeter spectroscopy to nuclear line emission astrophysics. B-MINE has a thin, plastic foil telescope multilayered to maximize the reflectivity in a 20 keV band centered at 68 keV and a microcalorimeter array optimized for the same energy band. This combination provides a reduced background, an energy resolution of 50 eV and a 3F sensitivity in 10⁶ s of 3.3 10^-7 ph cm^-2 s^-1 at 68 keV. During the course of a long duration balloon flight, B-MINE could carry out a detailed study of the 44Ti emission line centroid and width in CAS A.
