- Abstract
The world’s first X-ray pulsar experiment satellite (XPNAV-1) was launched by China on November 10th, 2016. The main payload of XPNAV-1 is a grazing incidence focusing X-ray pulsar detector (iFoXPD) which was developed by the Beijing Institute of Control Engineering of China Academy of Space Technology (CAST). The scientific objectives of XPNAV-1 were to: detect the Crab pulsar and research its radiation characteristics; obtain the profile of Crab according to the in-orbit observed data; verify the feasibility of pulsar detecting technical proposal and the performance of payload. The iFoXPD is composed of multi-layer nested Wolter-I X-ray optics, silicon drifted detector, magnetic diverter, electronics, stable structure, micro star sensor, etc. Based on the full reflection theory, the Wolter-I optics reflect and focus the X-ray photons radiated by pulsar onto the silicon drifted detector. Both the time of arrival and energy of each photon can be recorded accurately through the read-out electronics. Finally, the profile of pulsar is obtained based on the time transformation model, period searching and profile folding algorithms. This paper mainly introduces scientific exploration mission, the scientific payload’s design, operational principle, design principles, performance indexes and construction. The preliminary observation results are also described in detail.
