The Large Hadron Collider is shutting down but when it comes back it will become more powerful than you can possibly imagine! 💥
Looking forward to the High-Luminosity LHC (technically more *luminous,* in the sense of having way more proton collisions, rather than necessarily more powerful) in 2030!

The #LHC at #CERN concludes its Run 3 today and is shutting down for Long Shutdown 3 (LS3). ⚛️
It's preparing for the upgrade to the High-Luminosity LHC (HiLumi LHC), which from 2030 will be much more “luminous”.🧪 🔭
(“Luminous” means many more proton collisions per second — not visible light).

To endure the increased beam intensities and stored energies of CERN's next hadron collider, the High-Luminosity #LHC, the beam dump system - an essential part of the accelerator's machine protection systems - must be upgraded.

And it should be ready to go by 2030.

look to the data flow of the high luminosity LHC for guidance imo
if you're making any sort of agent harness thing and you want it to still be useful in like, five years, you need to be thinking about dealing w/ like megatokens/sec
