TL;DR: The X-ray Imaging Polarimetry Explorer (XIPE) as mentioned in this paper was proposed in 2012 to the first ESA call for a small mission with a launch in 2017, but the proposal was, unfortunately, not selected.

TL;DR: The X-ray Imaging Polarimetry Explorer (XIPE) as mentioned in this paper is composed of two out of the three existing JET-X telescopes with two Gas Pixel Detectors (GPDs) filled with a He-DME mixture at their focus, and two additional GPDs filled with pressurized Ar DME facing the sun.

TL;DR: The Ultra-Fast Flash Observatory (UFFO) as discussed by the authors uses a fast-response Slewing Mirror Telescope (SMT) that uses a rapidly moving mirror or mirror array to redirect the optical beam rather than slewing the entire spacecraft to aim the optical instrument at the GRB position.

TL;DR: In this article, a general description of the SPI Coded Mask design together with its main features is presented and results obtained for Mask calibration at different energies and incident angles are presented.

TL;DR: The Ultra-Fast Flash Observatory (UFFO) Burst Alert and Trigger Telescope (UBAT) was designed and built for the localization of transient X-ray sources such as Gamma Ray Bursts (GRBs) as discussed by the authors.
