Paralleled Thyratrons Structure Used in Metal Vapor Laser Power Supplies

In this study, the design and operational performances of a double thyratron, model TGI1 1000/25, connected in paralled to be applied in metal vapor lasers (MVLs) and their effects on heat dissipation and other limiting factors such as average current ; plate breakdown and anode heating factors; are presented. The sharing frequency between the used thyratrons is the main factor which is used in the applied design. Our measurements for the ohmic and capacitive loads, and also the laser tube with the use of anode tank water temperature measurements to obtain the heat dissipation in two different designs consist of single and double thyratrons configurations show that in the latter design, the average current and the heat dissipation are reduced to their half values compared to those of the former design. With the obtained experimental results, it is possible to apply a number of low power thyratrons in high power MVL lasers, where their input electric powers are higher than 2.5kW.
