Latest FlashLamp
Just a techy photo of the latest flash-lamp design. It seems to be working great, I have not had the inner or outer tube break in a long time.
I originally changed one flash to this design, now it is all three.
The inner tube is about 3./8 inch diameter and the outer is 1.25 inch diameter. The white object running through the center tube is a Delrin support for the copper trigger wire. I am just trying to get the trigger as close to the spark gap as possible so that triggering is better.
In my judgement, the only really important change is the inner quartz tube. It is a commercially prepared tube vs the hand sealed tubes I was using before. For some reason, it seems to be holding up very well.
I actually had a close look at the Pyrex inner tube I was using before I rebuilt it and the surface of the tube was covered with a very fine array of cracks. I assume that the cracks eventually catastrophically fail and cause the flash-lamp to stop working.
Cheers.
