摘　　要：测角仪是X荧光光谱仪的核心部件，由南京地质矿产研究所研制的HYY-G1／1000型高精度测角仪，采用θ轴和2θ轴独立控制的设计方式，其定位精度优于万分之五度，可实现双轴联动、单动，连续和步进扫描。本文采用MillimarC1245型电感测微仪对HYY-G1／1000的性能进行检测，结果表明：测角仪运行过程中涡轮盘平行度0．03mm、双轴同心度0．02mm、角度重复性优于0．001°、真空度小于1Pa，完全满足设计要求，并通过X荧光光谱仪捡定规程的检定。HYY-G1/1000 High Precision Goniometer, which is designed by Nanjing Center, China Geological Survey, is an important component of X-ray fluorescence spectrometer. The goniometer has two independent axles with 5/10000°positioning-precision, which can achieve single or union action,continue or step scan. In this paper, the performance of HYY-G 1 / 1000 is tested by MillimarC 1245 inductance micrometer, its parallelism of turbinedisk is0.03mm, concentricity is 0.02mm, angle- repeatability is better than0.001°, and vacuum degree is little than 1Pa.The working- parameters of HYY-G1/1000 Goniometer meet design-requirement and succeedin detection of X-ray fluorescence spectrometer verification regulation
