摘要

eXTP(增强x射线计时和偏振测量)任务是中国科学院(CAS)的一个重大项目,欧洲有很大的参与。eXTP的科学载荷包括四种仪器:由中国主导的SFA(光谱聚焦阵列)和PFA(偏振聚焦阵列)- LAD(大面积探测器)和由欧洲(意大利和西班牙)主导的WFM(宽视场监测仪)。他们提供了一个独特的同时宽频带x射线定时和偏振灵敏度。WFM是一种2-50 keV能量范围内的宽视场x射线监测仪器,由6台视场为180°x90°、角分辨率为5角分的编码掩模相机阵列和4台硅漂移探测器组成。它前所未有的大视场和低至2kev的成像组合将使eXTP能够对可变和瞬变x射线天空做出重要发现,并且对于探测瞬变黑洞至关重要,这是eXTP主要科学目标的一部分,因此可以迅速与eXTP上和其他地方的其他仪器进行跟踪。

The wide field monitor onboard the Chinese-European x-ray mission eXTP
The eXTP (enhanced x-ray timing and polarimetry) mission is a major project of the Chinese Academy of Sciences (CAS), with a large involvement of Europe. The scientific payload of eXTP includes four instruments: the SFA (spectroscopy focusing array) and the PFA (polarimetry focusing array)—led by China —the LAD (large area detector) and the WFM (wide field monitor)—led by Europe (Italy and Spain). They offer a unique simultaneous wide-band x-ray timing and polarimetry sensitivity. The WFM is a wide field x-ray monitor instrument in the 2-50 keV energy range, consisting of an array of six coded mask cameras with a field of view of 180°x90° at an angular resolution of 5 arcmin and four silicon drift detectors in each camera. Its unprecedented combination of large field of view and imaging down to 2 keV will allow eXTP to make important discoveries of the variable and transient x-ray sky and is essential in detecting transient black holes, that are part of the primary science goals of eXTP, so that they can be promptly followed up with other instruments on eXTP and elsewhere.
