A high color temperature, pulsed axial flashlamp which is very simple to build is described. The radiation is produced in argon or helium gas which is contained in an alumina tube at atmospheric pressureand allowed to flow out into the atmosphere through a hollow anode. At current densities of 40 kA/cm(2) (in a 1.5 cm(2) bore) the helium plasma radiates like a 30,000 K blackbody and can produce about one W/ angstrom of uv radiation in a f/8 solid angle. The voltage vs current relation of the arc discharge is ofthe form upsilon = K(0)|i|((1/2)) which allows one to design an R, L, C series discharge circuit which can produce a critically damped current pulse of arbitrary length.
描述了一种结构非常简单的高色温脉冲轴向闪光灯。辐射是在大气压下氧化铝管内的氩气或氦气中产生的，并通过空心阳极流入大气。在40 kA/cm²的电流密度下（在1.5 cm²的孔径中），氦等离子体的辐射类似于30000 K的黑体，并且在f/8立体角内可以产生约每埃一瓦的紫外线辐射。电弧放电的电压与电流关系为υ = K(0)|i|^(1/2)，这使得人们能够设计一个R、L、C串联放电电路，该电路可以产生任意长度的临界阻尼电流脉冲。
