我们给出了属于第三次剑桥修订星表(3CR)的9个射电源的分析，其中$Chandra$在第20周期红移1.5至2.5范围内被观测到。这项研究完成了3CR$Chandra$Snapshot调查，从而保证了迄今为止确定的所有3CR来源的X射线覆盖范围。这个样本列出了两个紧凑的陡谱来源，四个射电星系和三个类星体。我们探测到了所有核的X射线辐射，只有3C 326.1和3C 454.1例外，9个源中有6个射电叶的X射线辐射置信度大于$\sim$5$\sigma$。我们测量了软(0.5-1keV)、中(1-2keV)和硬(2-7keV)X射线带中所有核和叶的X射线通量和光度。由于所发现的X射线扩展发射在所有情况下都与射电结构在空间上一致，其起源可能是由于射电叶中发生的宇宙微波背景(IC/CMB)的逆康普顿散射。
We present the analysis of nine radio sources belonging to the Third Cambridge Revised catalog (3CR) observed with $Chandra$ during Cycle 20 in the redshift range between 1.5 and 2.5. This study completes the 3CR $Chandra$ Snapshot Survey thus guaranteeing the X-ray coverage of all 3CR sources identified to date. This sample lists two compact steep spectrum sources, four radio galaxies and three quasars. We detected X-ray emission from all nuclei, with the only exception of 3C 326.1 and 3C 454.1 and from radio lobes in 6 out of 9 sources at level of confidence larger than $\sim$5$\sigma$. We measured X-ray fluxes and luminosities for all nuclei and lobes in the soft (0.5 - 1 keV), medium (1 - 2 keV) and hard (2 - 7 keV) X-ray bands. Since the discovered X-ray extended emission is spatially coincident with the radio structure in all cases, its origin could be due to Inverse Compton scattering of the Cosmic Microwave Background (IC/CMB) occurring in radio lobes.
