THESEUS is a space mission concept, currently under Phase A study by ESA as candidate M5 mission, aiming at exploiting Gamma-Ray Bursts for investigating the early Universe and at providing a substantial advancement of multi-messenger and time-domain astrophysics. In addition to fully exploiting high-redshift GRBs for cosmology (pop-III stars, cosmic re-ionization, SFR and metallicity evolution up to the "cosmic dawn"), THESEUS will allow the identification and study of the electromagnetic counterparts to sources of gravitational waves which will be routinely detected in the late '20s / early '30s by next generation facilities like aLIGO/aVirgo, LISA, KAGRA, and Einstein Telescope (ET), as well as of most classes of X/gamma-ray transient sources, thus providing an ideal synergy with the large e.m. facilities of the near future like, e.g., LSST, ELT, TMT, SKA, CTA, ATHENA. These breakthrough scientific objectives will be achieved by an unprecedented combination of X/gamma-ray monitors, providing the capabilities of detecting and accurately localize and kind of GRBs and may classes of transient in an energy band as large as 0.1 keV - 10 MeV, with an on-board NIR telescope providing detection, localization (arcsec) and redshift measurement of the NIR counterpart. A Guest Observer programme, further improving the scientific return and community involvement is also envisaged. We summarize the main scientific requirements of the mission and provide an overview of the updated concept, design (instruments and spacecraft) and mission profile.
The XGIS instrument on-board THESEUS: Monte Carlo simulations for response, background, and sensitivity
瞬态高能天空和早期宇宙勘测者(THESEUS)飞行任务中的X和伽马成像光谱仪仪器的响应是欧空局在宇宙视野M5发射机会的框架内选定的评估阶段,已经用基于Monte Carlo Geant-4的软件进行了广泛的建模。本文描述了THESEUS计划中预计的近地轨道背景源(如漫射光子背景、宇宙射线粒子数、地球辐射),并给出了模拟的星上背景环境及其对仪器性能的影响。

The XGIS instrument on-board THESEUS: the detection plane and on-board electronics
THESEUS飞行任务(由欧空局在目前处于A阶段的宇宙视野M5发射机会框架内选定)上的X和伽马成像光谱仪仪器是以由数千个单个有源元件组成的探测平面为基础的。每个元件包括一个4.5x4.5x30 mm 3 CsI(Tl)闪烁体棒,两端与硅漂移探测器(SDD)光学耦合。SDD既充当闪烁光的光电探测器,又充当直接X射线传感器。本文回顾了XGIS探测飞机的设计,概述了系统模块化和冗余方面的战略选择。还描述了检测器电子原型的结果。此外,低噪声前端电子的设计和开发,强调创新的架构设计的基础上定制设计的专用集成电路(ASIC)。
