Abstract
Summary High pressure discharges are defined to be similar, when the temperature at homologous points of the discharge is the same. It is found that discharges in tubes of different diameters d, filled with different quantities of mercury m pro cm of length and operated at different energy inputs L pro cm of length, are similar when L is proportional to (A+Bm) A is interpreted as energyloss of the discharge independent of m (conduction of heat), Bm as the loss proportional to m (radiation). It is calculated, neglecting the small dependency of the gradient G on L, that the gradient should obey the relation G=m¼(A+Bm)½/d-1½ which is found to be in agreement with the experiments. From these measurements of the gradient the quantities A and B are determined to be 8,5 104 resp. 5,75 104 (G in Volts/cm, m in mg/cm and d in mm). The efficiency of the radiation may be calculated in similar discharges. With increasing m and L, L always being proportional to (A+Bm), the efficiency will increase and approach a limit which is in agreement with the measurements. The slow variation of the gradient as a function of L is made plausible and may be derived from the measured intensity of the radiation as a function of L.
