摘要:

LOFT(X射线定时大型天文台)是欧空局考虑作为M3任务(2022-2024年发射)的五个候选者之一,并在广泛的评估阶段进行了研究。它是专门设计来执行快速X射线计时和探测黑洞和中子星附近物质的状态。它的主要仪器是大面积探测器(LAD),这是一种在2- 30 keV范围内工作的10 m2级仪器,它具有在毫秒时间尺度上彻底改变X射线源变异性研究的能力。LAD仪器现已完成评估阶段,但尚未被选定用于发布。然而,在评估过程中,大多数权衡已经结束,导致一个强大的和有据可查的设计,将在未来的欧空局电话重新提出。在这次演讲中,我们将总结LAD设计的特点,并概述对仪器功能的期望。

英文摘要:

LOFT (Large Observatory for X-ray Timing) is one of the five candidates that were considered by ESA as an M3 mission (with launch in 2022-2024) and has been studied during an extensive assessment phase. It is specifically designed to perform fast X-ray timing and probe the status of the matter near black holes and neutron stars. Its pointed instrument is the Large Area Detector (LAD), a 10 m 2 -class instrument operating in the 2-30keV range, which holds the capability to revolutionise studies of variability from X-ray sources on the millisecond time scales. The LAD instrument has now completed the assessment phase but was not down-selected for launch. However, during the assessment, most of the trade-offs have been closed leading to a robust and well documented design that will be re- proposed in future ESA calls. In this talk, we will summarize the characteristics of the LAD design and give an overview of the expectations for the instrument capabilities.
