空间科学研究所的30米x射线铅笔束线已经升级。真空室已被直径1.8米、长11.3米的新圆柱形室所取代。安装了望远镜和探测器的台阶也被更换了。同时，介绍了一种新型的由两种尺寸组成的电荷耦合装置。探测器级可以沿着真空室中的x射线束移动，这使我们能够改变样品与探测器之间的距离，从0.7到9 m。这两个阶段可以在与x射线光束垂直的平面上的一个正方形区域内移动。样品和探测器级的Y方向运动轴（水平和垂直于光束）的俯仰有些大，但不超过60弧秒。其他轴的俯仰和所有轴的偏航都小于30弧秒。对于滚动，由于测量困难，我们只能得到上限。探测器级移动轴的Z方向（垂直于光束）的上限较大，约为60弧秒，其他轴的上限均小于30弧秒，并对光束线性能进行了总结。升级后不久，ASTRO-H软x射线望远镜在这条光束线上进行了校准。
The 30-m x-ray pencil beam line at the Institute of Space and Astronautical Science has been upgraded. The vacuum chamber has been replaced by a new cylindrical chamber of diameter 1.8 m and length 11.3 m. Stages on which a telescope and detectors had been mounted were also replaced. At the same time, a new charge-coupled device consisting ofof sizewas introduced. The detector stage can be moved along the x-ray beam in the vacuum chamber, which enables us to vary the distance between the sample and the detectors from 0.7 to 9 m. The two stages can be moved in a square regionin the plane normal to the x-ray beam. The pitching of moving axes of Y direction (horizontal and normal to the beam) of the sample and the detector stages is somewhat large, but does not exceed 60 arc sec. The pitching of the other axes and the yawing of all the axes are less than 30 arc sec. As for rolling, we could obtain only the upper limits because of the difficulty in measuring them. The upper limit of the Z direction (vertical and normal to the beam) of the detector stage moving axis is somewhat large and is about 60 arc sec, and those of the other axes are less than 30 arc sec. A summary of the beam line performance is presented. Soon after the upgrade, the ASTRO-H Soft X-ray telescopes were calibrated in this beam line.
