The LOFT mission concept is one of four candidates selected by ESA for the M3 launch opportunity as Medium Size missions of the Cosmic Vision programme. The launch window is currently planned for between 2022 and 2024. LOFT is designed to exploit the diagnostics of rapid X-ray flux and spectral variability that directly probe the motion of matter down to distances very close to black holes and neutron stars, as well as the physical state of ultra-dense matter. These primary science goals will be addressed by a payload composed of a Large Area Detector (LAD) and a Wide Field Monitor (WFM). The LAD is a collimated (<1 degree field of view) experiment operating in the energy range 2-50 keV, with a 10 m^2 peak effective area and an energy resolution of 260 eV at 6 keV. The WFM will operate in the same energy range as the LAD, enabling simultaneous monitoring of a few-steradian wide field of view, with an angular resolution of <5 arcmin. The LAD and WFM experiments will allow us to investigate variability from submillisecond QPO's to year-long transient outbursts. In this paper we report the current status of the project.
Optimisation of the design for the LOFT Large Area Detector Module
LOFT（X射线定时大型天文台）是一个X射线定时天文台，与其他四个候选者一起，被欧空局视为M3任务（2022-2024年发射），并在广泛的评估阶段进行了研究。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 m 2级仪器，旨在以前所未有的分辨率对紧凑物体进行X射线计时，分辨率低至毫秒时间尺度。虽然LOFT没有被选中发射，但在评估过程中，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中重新提出。LAD仪器的构建块是模块，在本文中，我们总结了模块概念的基本原理，模块的特点和权衡/优化，导致目前的设计。
The digital data processing concepts of the LOFT mission
大型X射线计时天文台（LOFT）是欧空局考虑用于M3任务的五个候选任务之一（发射机会在2022 - 2024年）。LOFT有两种仪器：大面积探测器（LAD）和宽视场监视器（WFM）。LAD是一种10 m 2级仪器，其收集面积约为迄今为止最大定时任务（RXTE）的15倍，首次结合CCD级光谱分辨率。WFM将持续监测天空并识别源状态的变化，检测瞬态和突发现象，并允许任务对此做出响应。使用LAD的有效面积观测最亮的X射线源会导致巨大的数据速率，这些数据速率需要在多个级别上进行处理，并在船上实时进行过滤和压缩。另一方面，WFM数据处理对数据速率的约束相当低，但需要算法来找到探测器上的光子相互作用位置，然后对探测器图像进行去卷积，以获得观测到的瞬态源的天空坐标。在下文中，我们将概述在研究阶段开发的数据处理概念。
