Nice bomb shots with the NANOSECOND SHUTTER CAMERA.

Far out! High energy physics. This blows my mind. It all happens in 20 nS, then the stuff is all used up

and no more chain reactions can occur. About 126 total I think. :cool:

Far out indeed. I think I've seen that picture, or one very like it, before. That bizarre bubble. It's beautiful, in a frightening way.

I cannot figure out how they made a camera so fast. Think of how fast the film had to move, if a movie
camera. Maybe it was just a bunch of simple one-shot single cameras, with a fancy nanosec trigger,
but what mechanical thing could move that fast? Baffling. :eek:

The tech and guts in the bomb are pretty interesting. They use "blasting caps" that are extremely fast,
the ultimate in electrical pulse generation. It is a vacuum tube, no solid state device can handle the HV.

Unlike most other gas switch tubes, the krytron uses arc discharge.

An electric arc is an electrical breakdown of a gas which produces an ongoing plasma discharge, resulting from a current flowing through normally nonconductive media such as air. A synonym is arc discharge. The phenomenon was first described by Vasily V. Petrov, a Russian scientist who discovered...

Not exactly the rite depiction, that cannot be described.. :twisted:

Your instincts are correct. A "bunch" of cameras with fancy, non-mechanical shutters.

Thanks Mee_n_Mac

I was wondering about the spikes in those shots and your links lead me this one.

Good new Mac! I have heard of Kerr cells used to optically switch laser beams. Polarizers, hmmm. Clever dudes

back then.
