© 2020 SPIE This document presents the preliminary results and discussion of the feasibility study of the 2nd generation of the X-ray Multi-Foil Optical (MFO) system for rocket experiment, namely an advanced Lobster Eye (LE) wide field X-ray telescope based on Multi-Foil Optics and designed for use in rocket flights

X-ray testing of the multifoil optical system REX II for rocket experiment

This paper presents the 2nd generation of the optical system for Rocket Experiment (REX2). This optical device is based on successful mission REX1. The purpose of REX2 is to verify X-ray optical system consisting of wide-field 2D X-ray Lobster-Eye (LE) optics with an uncooled Quad Timepix3 detector (512x512 px @ 55 um and spectrometer (active area 7 mm2, 145 eV @ 5.9 keV). The 2D X-ray Lobster-Eye (LE) optics is a combination of two one-dimension LE modules with a focal length of up to 1 m and a FOV better than 4.0 x 4.0 deg. The proposed optical system has imaging capabilities (2.5 to 30 keV) and spectroscopy capabilities (0.2 to 10 keV). The optical system was recently tested in the X-ray vacuum chamber. The preliminary test results are presented and discussed in this paper

GRBs and Lobster Eye X-Ray Telescopes

A large majority of GRBs exhibit X-ray emission. In addition, a dedicated separate group of GRB, the XRFs, exists which emission dominates in the X-ray spectral range. And the third group of GRB related objects (yet hypothetical) are the group of off-axis observed GRBs (orphan afterglows). These facts justify the consideration of an independent experiment for monitoring, detection and analyses of GRBs and others fast X-ray transients in X-rays. We will present and discuss such experiment based on wide-field X-ray telescopes of Lobster Eye type. We show that the wide field and fine sensitivity of Lobster Eye X-ray All-Sky Monitor make such instruments important tools in study of GRBs

X-ray multi-foil optical system for CubeSat demonstrator

Copyright © 2018 SPIE. The paper presents the X-ray Multi-Foil Optical (MFO) system proposed for the CubeSat demonstrator. The Lobster Eye (LE) design represents wide field of view (FOV) X-ray optics. This feature is unique in comparison with classical Wolter types of X-ray optics that reaches a field of view of typically 1 degree or less. LE optics can theoretically achieve an unlimited field of view, but for practical reasons, modules with, for example, 6 deg x 6 deg large FOV can be designed, developed, and constructed. Presented theoretical study of the Multi-Foil wide-field X-ray "Lobster eye" based optics shows effects of focal length, foil spacing and reflective surface (Au versus Ir). The main parameters that have been compared are effective area, gain, FWHM and/or transmission. The system can be used as an all-sky monitor in future projects

The experiment was performed by the PennState University with X-ray spectroscope on board a Water Recovery X-Ray Rocket (WRXR) launched on 4th April, 2018. The secondary payload was the REX LE X-ray Telescope. The REX LE X-ray telescope consists of two X-ray telescopes with one-dimensional (1D) and two-dimensional (2D) optics, a visible-light camera and an IR grid-eye. The primary structure consists of a metal housing for the optics and a carbon fiber baffle with the Timepix sensors mounted at the end. The observation data from the experiment are briefly presented and discussed
