The radiant intensity of VUV emission lines of a high-current hollow-cathode source has been determined for the 40-125-nm spectral range. The source is operated at a constant current of 1 A with an aluminum cathode. Different rare gases are alternatively used as the buffer gas at pressures of ~100 Pa. The radiant intensity has been determined by comparison with the calculable spectral radiant flux of the electron storage ring BESSY. Radiant intensities of the emission lines are in the 7-1400-µW/sr range. The long-term reproducibility of the radiant intensity of the source is within ±10% (2σ value). The systematic uncertainty of the radiometric calibration is better than 9% (√32σ value).
已测定了高电流空心阴极源在40 - 125纳米光谱范围内真空紫外发射线的辐射强度。该源使用铝阴极，以1安的恒定电流运行。在约100帕的压力下，交替使用不同的稀有气体作为缓冲气体。通过与电子储存环BESSY的可计算光谱辐射通量进行比较来确定辐射强度。发射线的辐射强度在7 - 1400微瓦/球面度范围内。该源辐射强度的长期再现性在±10%（2σ值）以内。辐射校准的系统不确定度优于9%（√3σ值）。
