Cosmic plasma conditions created in an Electron Beam Ion Trap (EBIT) make it possible to simulate the dependencies of key diagnostic x-ray lines on density, temperature, and excitation conditions that exist in astrophysical sources. We used a microcalorimeter to measure broad band spectra obtained from the NIST EBIT with an energy resolution approaching that of a Bragg crystal spectrometer. Spectra are presented for nitrogen, oxygen, neon, argon , and iron in various stages of ionization.
