題目：The Imaging X-ray Polarimetry Explorer (IXPE)

摘要：The next NASA Small Explorer (SMEX) mission, IXPE ( Imaging X-ray Polarimetry Explorer) , will be launched in 2021, with three identical X-ray mirror module assemblies and Gas Pixel Detectors (GPD). IXPE introduces the capability for X-ray polarimetric imaging, uniquely enabling the measurement of X-ray polarisation with scientifically meaningful spatial, spectral, and temporal resolution. During its baseline two-year operation, IXPE will have polarisation measurements on a few dozen sources, including various types of neutron stars, blackhole systems, active galactic nuclei, and supernova remnants, help to probe the origin and destiny of our universe. A series of simulation activities together with the calibration for flight units are in progress. The polarimeter design and expected performance will be discussed.

個人簡歷：2016年于中國科學院高能物理研究所獲得博士學位，博士期間的課題是關于HXMT和SVOM的在軌工作性能和本底研究。之后兩年在瑞典皇家理工學院從事博士后研究，主要參與的項目有由歐空局ESA主導的氣體偏振探測器XIPE和瑞典空間局主導的伽馬暴偏振探測器SPHiNX。目前工作于意大利國家天體物理研究所INAF，參與NASA即將于2021年發(fā)射的X射線偏振成像望遠鏡IXPE的研制，在合作組內(nèi)負責標定數(shù)據(jù)分析和模擬以及本底研究。
