For anyone interested in doing some very special visits this will be a good timing. Long Shutdowns are the only moments where a lot of usually inaccessible places can be visited.

There should be (not yet officially confirmed) an open days after summer next year, just like there was in 2019. Short time frame but for a few days everything(-ish) is accessible, including going down in the LHC tunnel, but many more crazy places.

In the meantime there are still permanent exhibitions and guided tours for those interested. Come have a look at the cool science (made with your taxes)!

Keep in mind this is for the hardware work. We have been working on the HL-LHC from the physics / beam dynamics / everything else side for close to a decade now.

The other machines in the complex, which we call "injectors" from our mighty tower, have already undergone their own upgrade to be ready for HL-LHC, the LIU (https://home.cern/accelerator-chain-prepares-high-luminosity...).

Nonetheless there are plenty of things to be done and a lot of technologically engaging challenges ahead so this 3-4 years is still ambitious ;)
