The Extreme Physics Explorer (EPE) is a mission concept which has been submitted to the recent NASA RFI for 'Concepts for the Next NASA X-ray Astronomy Mission'.
It utilizes a high TRL foil optic mirror with 1 arcmin PSF and direct heritage to Astro-H, and a micro-calorimeter which can deliver 2eV spectral resolution and 80% throughput at several Crab fluxes, and remains photon limited down to fluxes of 2e-14 ergs/cm2/s. The effective area for the foil mirror is >20x ASTRO-H, and a low-TRL micro-channel plate option could provide 200x the ASTRO-H effective area. EPE can address a significant fraction of the IXO science as outlined in the RFI, at a cost well within the medium category as defined by the RFI. While ASTRO-H will give us the first taste of the 'integral field' spectroscopy possible with a micro-calorimeter, EPE will provide us with the first statistically significant samples within many classes of objects.
We will discuss both the science reach and the technologies of EPE in this poster.
