用CCD相机测量中性束的空间密度分布

MEASUREMENT OF DENSITY PROFILES OF NEUTRAL BEAMS WITH A CCD CAMERA

利用CCD(电荷耦合装置)相机所成象的光强度峰值拟合中性束中三种能量成分的空间密度分布。本文给出象光强度的峰值坐标,滤光片中心波长与束能量和束的观察方向夹角的关系,束能量与束的观察方向夹角的关系及实验结果。

The density profiles of three energy components in neutral beams are derived from the image peaks in the CCD (Charge Coupled Device) camera pictures. This paper gives the image peak coordinates, the relation of the central wavelengths of filters with the beam energies and the beam-observation angles, the relation between the beam energies and the beam observation angles, and experimental results.
