Last week I had the chance to visit CERN's Antimatter Factory, and let me tell you I was feeling like a child on Christmas Day. The ridiculously advanced technology required to produce only a few picograms of antimatter is truly impressive. That they are considering sending it hundreds of km away is mind blowing.

I've seen this expressed before, but every picture I've seen of CERN just looks like a massive pile of wiring, magnets and generic electronics. So I'm not sure why people react like you do towards it. Is it different from seeing it in pictures? To me things like tokamak fusion reactors or rockets or even places like the massive piles of pipe work outside of SpaceX's launch site feel way cooler.

Because we are massive science nerds. I have been interested in this kind of stuff since I was a little kid. Which leads to the second point...

I ended up working at another accelerator facility, so even though I am an IT guy, I actually understand what I am looking at, which helps to increase the enjoyment.

That's awesome. My wife and I have been thinking about visiting CERN too. Curious, what part of the visit stood out as especially impressive? Last I checked, there was a pretty long waiting list for tours.

I worked at CERN a few years ago, so assuming they haven't build any new amazing facilities, these would be my top picks: - Any of the experiments really, but especially ATLAS is impressive. - The antimatter factory. I found that the guides there are usually very passionate. - The control centre if you can get a tour (this is the facility I delivered software to).

I work for the control group at another accelerator, so we were visiting and meeting their control guys. Super friendly people all of them, they treated us like kings... and their control centre is bigger than our whole facility xD

Energy. Creating a single anti-hydrogen atom requires an absurd amount of energy to first create a collision in a particle accelerator and then capture that anti-hydrogen before it eliminates against another atom. Only about 0.01% of the energy used to operate the particle collider creates antimatter, the vast majority of which is impossible to capture. All in all, the efficiency of the entire process - if you were t…

Has there been research on more efficient ways to generate antiprotons? (By the way anti-hydrogen isn't how you would store it as anti-hydrogen can't be trapped.)

Anti-hydrogen is routinely trapped in magnetic traps at CERN.

When I look at that pile, I see hundreds or thousands of devices that need to be working in concert to produce a meaningful result. Devices that need to be triggered exactly when the particle bunch travels by at near speed of light. These devices then generate data that needs to be stored somewhere and in a way that is later useful to the scientists.

The complexity hiding within the pile is immense, and that is what makes it impressive to me.

I see about the same thing as you do, only I am basically also picturing Ghostbusters who also had some very specific tooling for trapping, containing, and transporting ghosts, which was all central to the plot of the original film.

I can just foresee a future asshole European mayor who swaggers into the CERN remote antimatter facility and shuts it all down, triggering Armageddon and a new rampage by the Sta-Puft Marshmallow Man.

I designed some of the kit in that building! (Specifically for the alpha G experiment) Super proud of it.

Imagine inventing something like a better coffee carafe and being able to say this about a sizable portion of notable structures.

Not sure why, but I found it amusing when they said that the antimatter "reached speeds of over 40 km/hour." Not sure what the speeds are at the point of its creation (there are knowledgeable folks on here who will know, I'm sure), but that must seem sloooooow in comparison.
