By compare arc
performances, it was determined that thorium tungsten cathode pressure is small
than cerium tungsten, 2% Tn-W13.0V, 2% Ce-W12.0V. The service life is related
with cathode spot. In xenon stroke light compared these two electrodes found,
cerium tungsten end face has slight cathode spot and has smaller loss, and the
service life is longer than thorium tungsten. In emission current density,
cerium tungsten arc column euphotic belt is bright and long and emission
current density is higher than thorium tungsten. When the diameter is large,
the minimum arc stability of various electrodes is similar, with the reduction
of diameter, the cerium tungsten electrode arc performance is good than other
electrodes. The lowest arc voltage of cerium tungsten is 12V, thorium tungsten
arc voltage is 30V, so cerium tungsten arcing is more simple.
