N2 - We introduce focusing optics and microcalorimeter spectroscopy to nuclear line emissionastrophysics with a balloon payload concept called, B-MINE. It is designed to probe the deepestregions of a supernova explosion by detecting 44Ti emission at 68 keV with spatial and spectralresolutions that are sufficient to determine the velocity distribution of the 44Ti emitting region. BMINEhas a thin plastic foil telescope multilayered to maximize the reflectivity in a 20 keV bandcentered at 68 keV and a microcalorimeter array optimized for the same energy band. Thiscombination provides a reduced background, an energy resolution of 50 eV and a 3F sensitivity in106 s of 6 × 10-8 ph cm-2 s-1 at 68 keV. During the course of a long duration balloon flight, B-MINEcould carry out a detailed study of the 44Ti emission line centroids and width in CAS A. Details ofthe spectrometer and simulated results are presented.
