Problems solved by technology

Therefore, in order to improve F / DCl / HI / HN 3 The small signal gain and output power of the all-gas-phase iodine laser system must increase the yield of F atoms, because the number of fluorine atoms directly affects and limits the efficiency of the system
Although the above reports all mentioned the generation of fluorine atoms by DC discharge, they did not mention the discharge mode and electrode structure of DC discharge.

Embodiment 1

[0021] Please refer to Fig. 1, the inventive device consists of an anode, a quartz discharge tube, and a double cathode structure. The anode 1 is a cylindrical cavity structure, cooled by circulating water inside, connected to the quartz tube 2 through a plexiglass sealing sleeve, the first cathode 3 is an annular cavity structure, and internally circulated for cooling, and is also connected to the quartz tube 2 through a plexiglass sealing sleeve. Connected, the second cathode 4 is a spiral coil structure, placed vertically in the downstream transition section of the air flow, and internally circulated for cooling. 5 is an air inlet for flowing gas. The gas flows through the discharge tube, flows out from the center of the cathode 3 ring, and collides with the cathode 4 to increase disturbance and strengthen mixing.

[0022] The above electrode structure can be applied to the stable discharge of flowing gas, increasing the concentration of active particles and improving the u...

Embodiment 2

[0024] The following uses the application of the F / DCl / HI / HN3 all-gas-phase iodine laser system as an example to illustrate the method of using the electrode structure of the present invention.

[0025] The applicant used the electrode structure of the mixed reaction gas discharge system to generate active particle fluorine atoms, and applied the invention to the F / DCl / HI / HN3 all-gas-phase iodine laser system for the first time, and studied the discharge characteristics and injection power of the gas Condition.

[0026] Please refer to Figure 2. Since the F / DCl / HI / HN3 all-gas-phase iodine laser system is a mixed reaction of four gas streams to generate excited iodine atoms, it is possible to perform gain measurement and light demonstration. In this embodiment, the electrode structure of the mixed reactive gas flow discharge system of the present invention is used to perform DC discharge on the mixed gas of NF3 / He to generate active particle fluorine atoms, and the main gas flo...

Description

technical field [0001] The invention relates to an electrode structure for flowing gas discharge, which improves the stability of gas flow discharge and strengthens the mixing between gas flows. The gas flow through this electrode structure not only increases the concentration of active particles, improves the stability of discharge, but also improves the utilization efficiency of active particles, thereby promoting the development of flowing gas discharge. Background technique [0002] The development of oxygen iodine chemical laser has a history of 20 years, and it also has a certain scale. Because the oxygen generator is a gas-liquid reaction, it is difficult to increase the volume specific power of the oxygen-iodine chemical laser. Therefore, reducing the volume and weight of the oxygen-iodine laser is limited. In 1990, Bower and Yang reported that NCl(a 1 The energy transfer of Δ)+I has attracted great attention from people all over the world. By NCl(a 1 Δ) Whether ...
