标题： The Chandra High Energy Transmission Grating: Design, Fabrication, Ground Calibration and Five Years in Flight

摘要： 文章介绍了在钱德拉X射线天文台上的高能传输光栅 (HETG) 的设计、制造、地面及飞行校准的细节，这是在飞行五年后得到的经验。具体内容包括应用于 HETG 的相位传输光栅理论、光谱仪的罗兰设计、光栅制造技术的细节以及 HETG 的地面测试和校准结果。在将近六年的运行中，HETG 基本上按照设计运行，尽管它带来了一些微妙的飞行校准效应。 显示英文摘要

摘要： Details of the design, fabrication, ground and flight calibration of the High Energy Transmission Grating, HETG, on the Chandra X-ray Observatory are presented after five years of flight experience. Specifics include the theory of phased transmission gratings as applied to the HETG, the Rowland design of the spectrometer, details of the grating fabrication techniques, and the results of ground testing and calibration of the HETG. For nearly six years the HETG has operated essentially as designed, although it has presented some subtle flight calibration effects.
