The Large Area Detector onboard the eXTP mission

(Additional authors not shown) The Large Area Detector (LAD) is the high-throughput, spectral-timing instrument onboard the eXTP mission, a major project of CAS and CNSA with a large European participation. The eXTP mission is currently completing its phase B study, with a target launch at the end-2029. The eXTP scientific payload includes four instruments (SFA, PFA, LAD and WFM) offering unprecedented simultaneous wide-band X-ray timing and polarimetry sensitivity. The LAD instrument design envisages a deployed 3 m2 effective area in the 2-30 keV energy range, achieved through the technology of the large-area Silicon Drift Detectors - offering a spectral resolution of up to 200 eV FWHM at 6 keV - and of capillary plate collimators - limiting the field of view to about 1 degree. In this paper we will provide an overview of the LAD instrument design, its current status of development and anticipated performance.
