Since the difference between the film and the quartz, there are problems in metallization process such as low bonding
strength, poor wettability and the film stress; combined with the actual situation, carried out a series of exploration of the
above problems, take different measures to solve the practical problems.
With method of fixing wire in the high power pulsed xenon lamp tube, an experimental device of double lamp series
was established to simulate the actual working environment of the xenon lamp. The experimental results show that the
thermal damage with the pre delay time of 150μs is much more serious compared with the pre delay time of 250μs. The
reason could be that the metastable particles formed by pre discharge are uneven with the former. The tube pale first
appears near the left lamp anode and the right lamp cathode. The possible reason is that bifurcates and shifts of the
plasma discharge channel are affected by the wire. The test results show that the main reason of thermal damage is that
the temperature of discharge plasma is uneven inside the tube. By improving the structure of the lamp box and
optimizing the pre delay time, the discharge plasma temperature can be decreased for the avoidance of the thermal
damage.
