Abstract

A pulse-periodic cesium discharge is studied in a wide range of its parameters in two lamps with burners of the same diameter (5 mm), but with different interelectrode spacings (55 and 22 mm). It is found that such a decrease in the length of the plasma column leads to a significant change in the properties of the discharge. In the longer burner, contraction of the discharge column occurs as the pressure increases with the localization of the plasma column at the wall of the discharge tube, and a significant increase in lamp efficacy is observed with a further increase in pressure. In the shorter burner, contraction occurs at lower pressures (specific powers) with the localization of the plasma column along the tube axis, and there is no increase in lamp efficacy with a subsequent increase in pressure.

高电流脉冲周期性铯放电作为可见辐射源的特征

摘要

在两个具有相同直径（5 毫米）但具有不同电极间距（55 和 22 毫米）的燃烧器的灯中，研究了在其广泛参数范围内的脉冲周期铯放电。发现等离子柱长度的这种减小导致放电特性的显着变化。在较长的燃烧器中，随着等离子柱在放电管壁上的定位，随着压力的增加，放电柱会发生收缩，随着压力的进一步增加，观察到灯效率显着增加。在较短的燃烧器中，随着等离子体柱沿管轴的定位，在较低压力（比功率）下发生收缩，并且随着压力的随后增加，灯效率没有增加。
