    • A gas discharge lamp, photoionization sensor employing the gas discharge lamp, and method of manufacture. The lamp (10) includes a housing (20) containing a working gas sealed within the housing, an ultra-violet transparent window (30) through a first longitudinal end of the housing, and a longitudinally extending strip of getter (40) within the housing.
      The method of manufacture includes the steps of (i) obtaining a glass tube, (ii) constricting the tube intermediate the longitudinal ends to divide the bore into first and second chambers in fluid communication with one another through a passageway in the constriction, (iii) attaching an ultraviolet transparent window over the open end of the first chamber, (iv) inserting a strip of getter into the first chamber through the passageway in the constriction, (v) purging the first chamber with a noble gas, and (vi) heating the tube at the constriction to detach the first chamber from the second chamber and seal the constricted end of the first chamber.
    • 一种气体放电灯,光致电离传感器用人气体放电灯,和制造方法。 所述灯(10)包括穿过所述壳体的第一纵向端部内的一个壳体(20)包含在外壳内封入工作气体,于紫外透明窗口(30),和吸气剂(40)的纵向延伸的条 住房。 该制造方法包括(i)获得的玻璃管的步骤,(ⅱ)收缩所述管的中间的纵向端部通过通道在收缩来划分钻入彼此流体连通的第一室和第二室,(ⅲ )附接在所述第一腔室的开口端于紫外透明窗口,(ⅳ)将吸气剂的一个条到第一腔室通过在收缩的通道,(ⅴ)用惰性气体吹扫所述第一腔室,和(vi) 在所述收缩加热该管以分离从所述第二腔室中的第一室和密封所述第一腔室的收缩端。
