Specifically, it provides high quality FUV spectra covering the diagnostic-rich 500-1050 Angstrom rest-frame of medium redshift objects. We have recently published a series of papers, based on the analysis of data supported by our concluded COS archive program, in which we reported: a) a new population of very high ionization outflows, b) robust cases of two-ionization-phase outflows, which are the missing link between UV AGN outflows and x-ray warm absorbers, and most importantly c) spectral diagnostics that allowed us to determine the distances of 2 such outflows from the central source, and thus their tomography and energetics. These findings demonstrate that quasar outflows have sufficient energy to confirm the theoretical predictions of the significance of AGN feedback processes, and go a long way towards answering some of the fundamental questions in the field of AGN outflows that have been around for more than 20 years. Here we propose a continuation of this very successful archive program. Thus far we've analyzed about 300 COS G130M and G160M orbits of AGN observations. There are roughly 600 additional orbits that satisfy our criteria and will be available by the end of this year, with an additional 300 orbits in the following year. Based on our published survey, we expect that these 900 orbits will yield 20-30 additional very-high ionization outflows and 4-6 cases of distance determinations, all in cosmologically important luminous-quasars.
