High Speed Camera up to 1000000 fps

[Henning]

There’s a new high-speed camera available:
http://www.visionresearch.com/Products/High-Speed-Cameras/v1610/
For 18100 fps the resolution is 1280 x 720, but for 1000000 fps the resolution is only 128 x 16.

I don’t know the price, though.

Rumors say it’s something between 50000 and 150000 USD, plus optional gear.

Maybe still better than the Framing Camera on the LPPX wishlist: https://focusfusion.org/index.php/site/article/lppx_wishlist_-_donate_equipment

Is it my imagination? I have watched the animated snapshots of fofu1 plasmoid formation hundreds of times now and wonder why the bright spot in the middle(plasmoid) seems to jump up by at least its diameter. is this a magnetic reaction with the center electrode? hot gas pressure? if the geometry was changed would that keep all of those hot ions in one spot? it seems to me that if it has heated the gas in that area enough to glow that energy is lost during the shift away from the electrode.

willit, you need to know how those animations were produced. It is not a single shot, but multiple shots in different phases combined in a single animation.

Yes, the plasmoids do move away from the anode( which is actually donw, but up in these images). The energy of thier translational motion is actually quite small compared with their internal energy. They expand as they move, so the period of fusion energy production is early in their lifetime, when the are closest to the anode.

By the way, it’s possible to rent those Phantom cameras:

For TV or motion picture there are rental partners:

For example at $2750 per day (for a TV shot):

Maybe you’ll need more equipment, like lenses.
And you’ll need to hire an technician for these cameras:

But it’s not the High-Speed Phantom v1610, only lower speed (125,000 fps at 256 x 64 pixels) Phantom v640:

Other thing I found for the Phantom v1610/v1210, the spectral curve:

yes i understand that the images were from multiple shots. I guess the crux of my thoughts was that the shift seemed to move away from the anode and I was interested to know if during the travel it was heating new gas as it went or if it was movement of the gas that was already in a plasma state. if the plasmoid was stationary in free space would yield be higher? if the fusion reactions happen sooner than it appears to shift would more reactions take place if it didn’t shift. of course i know that magnetic interactions occur and force things in different directions but it occurred to me that if the anode were another set of rods that had less magnetic interaction results could be different.

remember that the internal combustion engine was refined from steam engine theory and that it came before turbine engines. it seems logical that an intermittent pulse power system would come before a continually powered system. focus fusion vs tokomak.
