Not really. https://home.cern/news/news/experiments/base-experiment-takes-big-step-towards-portable-antimatter https://home.cern/news/news/experiments/base-exp

  That’s because it’s not really a hazardous material. 70 antiprotons annihilating with 70 protons releases a grand total of 2×10⁻⁸ Joules.

    That exponent is still a lot larger than I would've expected for something measured in three digits of atoms. I thought it would've been in the double negative digits.

      Yea, c² is pretty big.

    Yeah. I bet in practice the liquid helium used to cool the trap is more dangerous than the actual antimater. It can cause cryogenic burns similar to frostbite, and if it suddenly boils off in a confined space (like inside a container or the back of a truck) it can displace oxygen and cause inert gas asphyxiation. Of course both of these can be managed easily with appropriate procedures. It is a bit like getting injured by pinching your hand in the hinge of the Velociraptor container in Jurrassic park. Not the first danger you would think of, but still present.

  This thing? I think it looks super cool. An 80-20 rectangle stuffed with science stuff. https://home.cern/sites/default/files/2024-10/1st-moving-crane-base-step.jpg https://home.cern/sites/default/files/2024-10/1st-moving-cra...

    Missed opportunity to slap on a big warning label saying "ANTIMATTER CONTAINMENT"

  Apparently there is no UN number for antimatter, disappointing. We could use UN 2910 or maybe UN 0357
