XL-Calibur is a balloon-borne Compton polarimeter for X-rays in the 15–80 keV range. Using an X-ray mirror with a 12 m focal length for collecting photons onto a beryllium scattering rod surrounded by CZT detectors, a minimum-detectable polarization as low as 3% is expected during a 24-hour on-target observation of a 1 Crab source at 45° elevation.

X 射线镜焦点处康普顿旋光计的系统效应

XL-Calibur 是一款气球载康普顿旋光计,适用于 15-80 keV 范围内的 X 射线。使用焦距为 12 m 的 X 射线镜将光子收集到由 CZT 探测器包围的铍散射棒上,在对 1 Crab 进行 24 小时的目标观测期间,预计最小可检测偏振低至 3%源位于 45° 仰角。
