Abstract

This paper presents (1) new laboratory data on the x-ray spectra of He-like Ar XVII over a broad spectral range (300-3500 eV) at high resolution (2) the results of new measurements of K-shell x- ray reference lines in carbon, oxygen, iron, copper, and aluminum which were then used to obtain an absolute calibration of our x-ray microcalorimeter efficiency function, and (3) a review of our laboratory astrophysics research program. The data will be used to improve our laboratory measurements of Ne-like Fe XVII which, together with the new argon data presented here are useful for interpreting observations from NASA's orbiting Chandra X-ray Observatory.
