Thermoelectric Cloud Chamber [1080p]

Demonstration of the "Cloudylabs" cloud chamber with some low activity radioactive sources. It works with 8 thermoelectric modules with a closed loop liquid cooler, so it can display the first particles within 1 min.
A magnet is put inside the machine, under the interaction surface, so during the whole video, a magnetic field is present and deflect the lightly charged particles (electrons).

These particles travel at or near the speed of light, so you wouldn't really see anything special. You won't see the trails being formed from one end to the other, if that's what you're hoping for.

[@GMCLabs]

@@weblure they might move that fast, but the condensations does not happen that fast, it lags behind as the particle moves past the molecules. Look up slow motion of lightning, you can see the acr trails as they form. The electricity moves through the air at near light speed, but the ionization of the airs lag behind too

[@weblure]

​@@GMCLabs Once a path is formed from cloud to ground, the lightning strike itself is nearly light-speed. You can't see the path it travels no matter how fast your camera records, because you can't record at light-speed. The trailing effect you see before that is seperate from the actual lightning strike. The particles passing through this chamber do not have any such effect. The particles move in one, continuous path at near the speed of light. Obviously, the condensation does not move at the same speed, or else we wouldn't be able to see the effect at all. The point is, all you'd see is the cloud expanding linearly in slow motion, which isn't really that interesting. The vapor cloud already expands slow enough to see with the naked eye -- what'd be the point of slowing that down? You won't see anything special that you can't already see.

[@weblure]

I gave you the benefit of the doubt and looked for a slow motion recording of lightning. Sure enough, once the trailing/branching effect ends, the lightning strike itself appears instantaneously. There's no traceable path from top to bottom, or vice versa. kzbin.info/www/bejne/p4KumXyBadWpj9E

[@GMCLabs]

@@weblure i understand that. Though there is videos of light moving in slow motion, its kinda "faked". They fire a laser pulse and record a picture, then fire another pulse and take a pic 1 femtosecond later. As for lighting how do explain this? kzbin.info/www/bejne/p4KumXyBadWpj9E You can clearly see the lighting traveling. I agreed the electricity has already reached the ground, but the plasma takes more time to reach temperature and become visible. Would think we would see the same thing in the cloud chamber. Might look cool to see the trails appearing in slow motion. You really can't say it would be "boring" untill someone actually does it. I know the slow mo guys get surprised by their own videos, and thats what they do for a living.

Incredible work & dedication, and what fruits! I've had partial success in building a cloud chamber myself using small Peltier tiles, got temp down to -50°c on surface.

[@pirobot668beta]

Some chambers use a charged grid above the viewing plate to make a electrostatic 'compression' field. The grid is about 20-80 mm above the plate. Any ion trails* formed between the gird and the viewing plate were 'squashed' into the vapor layer. I ran the cloud chamber at Pacific Science Center a while back. Cooling was by a 'refrigerator compressor' set at -20C, plate was 620mm x 750mm. Vapor layer was around 3-5mm thick. 20 minutes to cool down. Recirculating pump kept a film of isopropanol on the viewing plate. Grid was around 15 Kv. No magnetic field. *The electrostatic grid can play favorites! The grid polarity determines if the chamber is showing negative or positive ion trails. Positive grid = positive ions on display. Negative grid = negative ions are putting on a show. Most ion trails are negative, BTW. Higher voltages make for sharper tracks and faster response, but they vanish quickly. Lower volts = thicker tracks, last a little longer. No volts = only ion trails formed in the vapor layers are visible, but they can persist for a long time.

Well, it likely will, but not from the fact of its electrical nature. These are high-energy particles - MeV range of energy per particle - while the energies of anything emitted by its electric circuits will be far smaller. Any emission from the phone will be due to radioactive trace impurities within its structure, just as here, but events will be rare because the amounts of such unstable nuclides within it are going to be very small - likely not much different from any other ordinary object.

Great video ... quite a bit more involved than the usual DiY setup using dry ice, alcohol vapor, and a flashlight, but the greatly enhanced visual clarity is totally worth it.

I also liked the historical easter egg at 4:22 using radium watch hands, which was an obvious callout to the late great Madam Curie who discovered it, and which for many decades was used to create a glowing paint used on the tips of analog watch hands ... like the ones used in this vid.
