Post-dispersed FTS Spectroscopy on SPICA-Safari

Willem Jellema, David A. Naylor, and Peter Roelfsema

Open Access Open Access

Abstract

The SPICA-Safari instrument, currently being proposed as an ESA M5 mission, requires line sensitivities of order 10–19 W/m2 (5σ-1hr) between 34–230 μm. In this paper we will give an overview of the mission and instrument. In particular we will present a cryogenic post-dispersed Martin-Puplett Interferometer scheme, utilizing extremely sensitive TES detector arrays, to implement a high-resolution mode (R ≈ 103–104), offering unprecedented spectroscopic observing capabilities in the far-IR.
