The optical radiation caused by electron bombardment of metallic surfaces was tested for its use as a secondary standard source in the VUV. Aluminum of high purity was found to be a suitable target material. The reproducibility of the radiation is of the order of 4% to 2% for 0.11 < lambda < 0.15 microm and 0.15 < lambda < 0.27 microm, respectively. In the spectral region 0.17 microm to 0.27 microm, the source was calibrated absolutely by comparison with a deuterium lamp of known absolute intensity.
对金属表面电子轰击产生的光辐射作为真空紫外区的二级标准源的用途进行了测试。发现高纯度铝是一种合适的靶材。对于0.11＜λ＜0.15微米和0.15＜λ＜0.27微米，辐射的再现性分别为4%至2%。在0.17微米至0.27微米的光谱区域，通过与已知绝对强度的氘灯比较对该源进行了绝对校准。
