Blasting A Cloud Chamber With Electrons

[@Sannypowa]

It amazes me how electrons are displayed as multiple rings of particles

[@dontworry4945]

All of a sudden all those electron orbital positioning numbers make sense. They're really out here in clouds of waves. Electromagnetism is an otherworldly force.

[@AllanChen-c2c]

actually the electrons might be driving a neutral wind that is causing the movement in the gas.

[@wayneschmidt490]

You're correct. The blast of electrons ionizes a low percentage of the alcohol atoms in the active layer, which act as nucleation sites for other atoms to condense on to create a cloud, then air put in motion by the flow of electrons creates a puff of air that blows the cloud around.

Thank you!

What if the sharpened copper wire tip is connected to a positive potential (positive Van De Graaff generator ) ?

[@wayneschmidt490]

the positive potential would draw electrons upward from the aluminum base plate. It would be the same as attaching a negative VDG to the base. I haven't done it but would expect the upward shower of electrons to form a uniform cloud in the active layer of the chamber. Thanks for commenting!

[@ucilkrucil4106]

Have you try to shoot laser pointer to the chamber?

[@wayneschmidt490]

I never thought off that! Interesting idea. Thank you!

[@AZsTopConnection]

@@wayneschmidt490definitely would like to see an updated video of a new experiment with this addition added to it

[@МихаилПетров-е8ш]

Old school nuclear physics :-)

[@wayneschmidt490]

You're right! But in their day, cloud chambers were ground-breaking devices. Thanks for commenting!

[@odal6770]

What would happen if you could stir inside the cloud chamber, say with a non-conductive stick. Would we get to see the tracks of the stirring?

[@wayneschmidt490]

That would be interesting to try. Unfortunately, I no longer have the cloud chamber. Thanks for writing!

[@odal6770]

@@wayneschmidt490 Too bad. Thank you for replying so swiftly.

[@Furos222]

the static-like noise generated after the cloud is made intrigues me. do you know what makes this sound? i would think its the electrons hitting the camera but im not sure

[@wayneschmidt490]

The buzzes and pops are sparks from the Van der Graaff generator and can be heard anytime it's in use. But you've raised an interesting point. The generator used puts out over 400,000 volts and can cause camera problems. To prevent the very thing you mentioned, the camera is located quite far away and a telephoto lens is used to get close ups. Thanks for commenting!

Why am I obsessed with particle physics, I’ll never be smart enough to understand anything!

[@wayneschmidt490]

I know what you mean. The best videos on the subject are from Fermi Lab, but no matter how many times I watch them I always come away confused. Here's a good one: kzbin.info/www/bejne/jorGqGuki8R6itU You can skip the first minute and a half without missing anything. It's just an introduction that doesn't really say anything. You're a race car driver?! Wow! I get nervous taking my minivan out on the freeway. Then again, the way people drive in my area of Southern California maybe I'd be safer on a track. I checked out your channel and enjoyed watching some of your videos. Is that your car (roadster?) or do you drive for someone else? Thanks for writing!

[@sara_7595]

@@wayneschmidt490 lol thanks. That’s what we call classics in Tennessee. It’s a metric chassis with a 305 engine and 350 turbo transmission. I have been listening to Daniel and Jorge explain the universe for years. I’m obsessed with particle physics and radioactive elements and nuclear power. But I’ve accepted I’ll never be that smart but it’s a fun hobby. Especially neutrinos!! I’ve always wondered if that could be a cause of cancer. One neutrino interacting on a rare occasion with a cell.. anyway have a good evening!

[@wayneschmidt490]

@@sara_7595 Okay. Let me apologize up front for the questions I'm about to ask. But, through no fault of your own, you've had the misfortune of mentioning things to an engineer that he's never heard of before. As a species, we are unable to resist asking questions about things we don't know. 🙂 First up: what's a "metric chassis?" A car made in meters instead of feet? Next: I've heard of turbo engines, but never a turbo transmission. I have an insane image of an exhaust-driven turbo charger pumping air and fuel a transmission, which is just wrong. What is a turbo transmission really?

[@YourAgentSarah]

Lol it’s ok. A metric chassis is the frame of a car like a Monte Carlo or a Buick. I’m actually not sure why it’s called metric! The 350 turbo transmission is/can be air cooled. They’d possible why it’s named that also

[@madshorn5826]

@@sara_7595 Don't sell yourself short :-) Studying something like particle physics takes grit more than smarts. Only when you want to contribute new _theoretical_ stuff smarts may be a factor. But having a hobby is fine too, and some amateurs have even contributed to science :-) If you don't know the site go have a look at the citizen science organization Zooniverse. They currently seeks help interpreting the ATLAS data from the LHC and would be grateful if you could donate some time. As for neutrinos causing cancer: It is possible as a neutrino can interact with a proton and result in a neutron and an electron. The resulting particles may harm DNA in rare cases,so with an estimated 100 billion humans throughout history it is plausible this have happened at some time. Compared to regular background radiation this is absolutely negligible though: We will never be able to ascribe a cancer case to a single neutrino. A nearby supernova could _maybe_ send out enough neutrinos to cause a blip in cancer rates, but I highly doubt it. The reason I ended up in this comment section is because I am building a tiny Peltier cooled cloud chamber for fun. It isn't that hard if you know your way around a workshop. If there is a hack space near you I'm sure you can get help there, if you need it.

да ведь это же взрыв в микро и макро вселенной!!!!

[@wayneschmidt490]

Я как-то об этом не подумал, но ты прав. Я просто рад, что это был небольшой взрыв, потому что я сделал это дома. :-)

[@djordjek3916]

To me it looks like ionized plasma cloud due to all cloud shapes indicative of plasma, in this case dusty plasma.

Surprised the government never shut this video down, lol - fantastic video, thank you.
