Abstract

The Microchannel X-Ray Telescope (MXT) is part of the Sino French SVOM mission mainly dedicated to Gamma-Ray Bursts (GRBs). MXT combines a “lobster-eye” focusing X-ray micro-pore optic with a pnCCD detector operating from 0.1 to 10 keV. A stable structure made of carbon fiber reinforced polymer (CFRP) and titanium connects the two parts and provides the interfaces with the satellite. After a short description of the instrument, this paper first presents the alignment process and the measurement of the line of sight (LOS) at MPEs PANTER facility in Germany. Then we focus on the prediction of the in-orbit LOS stability combining thermos-elastic simulations and dedicated measurements.
