 .:: Pulsed Filiment ::.
|
Purpose:
The purpose of this experiment is to generate a super intense beam of light by pulsing an ordinary low power filiment causeing it to atomize. This experiment was also caried out to better understand the effects and behavior of wire explosion.
Materials:
- Mirrored parabolic reflector
- Small average 6V light bulb
- Capacitor bank 16uF @ 5kV
Details:
I set up the parabolic reflector facing the camera and attached aligator clips to both leads that came from the light bulb base. I connected the aligator clips to my pulsing module. When the light bulb was inserted into the reflector, I had to identify where the focal point of the parabola was. I used the formula f = (D^2)/(16*c), where f = focal distance; D = diameter of parabola; c = depth of parabola. I placed the bulb inside and was ready to pulse.
Images:
The following series of images were taken from a video recording of the experiment. There is a 33.4mS delay between each frame.
Frame 01 (0mS)
Frame 02 (33.4mS)
Frame 03 (66.8mS)
Frame 04 (100.2mS)
Frame 05 (133.6mS)
Frame 06 (167.0mS)
Frame 07 (200.4mS)
Frame 08 (233.8mS)
Conclusion:
The output beam was very intense but lasted for only a few microseconds. You can observe the destruction of the parabolic reflector and enclosure shortly after the pulse.
