摘要:

LOFT任务的科学目标,例如,对中子星状态方程和强引力的研究,需要对SDD探测器的500k通道进行精确的能量、时间和通量校准,以及探测器死区时间和探测器相对于光子入射角的响应的知识。我们在这里报告的评价,以评估LAD仪器的校准问题。包括天体物理观测在内的地面和星上校准战略表明,这些目标在现有技术范围内是可以实现的。

英文摘要:

The Scientific objectives of the LOFT mission, e.g., the study of the Neutron Star equation of state and of the Strong Gravity, require accurate energy, time and flux calibration for the 500k channels of the SDD detectors, as well as the knowledge of the detector dead-time and of the detector response with respect to the incident angle of the photons. We report here the evaluations made to asses the calibration issues for the LAD instrument. The strategies for both ground and on-board calibrations, including astrophysical observations, show that the goals are achievable within the current technologies.
