The test stand for the #HiLumiLHC, the IT String, just hit its operating temperature: 1.9 Kelvin – only two degrees above the absolute zero, the coldest temperature possible.

Today, she shares insights into the future plans for the world’s largest machine as we prepare to transform the LHC into the #HiLumiLHC, a groundbreaking accelerator that will usher in a new era for high-energy physics.
With proton collisions at 13.6 TeV, this season is special not only because it begins earlier than usual, but also because it will be the last time the LHC operates in its current form. After this run, the LHC will be shut down for four years, returning in 2030 as the #HiLumiLHC.
The CMS Inner Tracker team has tested the new silicon pixel detector modules at the CERN’s #HiRadMat (High Radiation to Materials) facility, in order to evaluate any potential damage to the detector in case of beam loss at #HiLumiLHC!

#HiLumiLHC : full-scale tests start 💫
Listen to Marta Bajko, Head of the High-Luminosity LHC Inner-Triplet (IT) String project, as she explains what will happen in the next weeks.

Here we see engineers at CERN assembling a beam screen for the #HiLumiLHC.
The beam screen is a device that surrounds the beam to protect neighbouring equipment from heat loads and potential damage caused by the circulating beams.
The #HiLumiLHC, expected to be operational from 2030, will significantly increase the collision rate, aiming for a total data collection (integrated luminosity) ten times higher than the original LHC design.
In the meantime, ATLAS physicists have been developing upgrades for the detector, incorporating cutting-edge technologies for the #HiLumiLHC era, which will provide more data than ever before.
Scientists #AtCERN have triggered the complex cooldown of a 95-m-long test stand that reproduces the underground configuration of innovative technologies for the LHC’s high-luminosity upgrade. #HiLumiLHC

Currently, these magnets deflect 160 MeV hydrogen ions, and were upgraded during long shutdown two to support the #LHC's transition to #HiLumiLHC.

Comment below if you would like to see a new #HiLumiLHC key being handed over after Long-Shutdown 3, when most of the high-luminosity upgrades will take place, scheduled to begin in July this year.
This test was a collective effort of robotics, vacuum, survey and transport teams, together with the #HiLumiLHC vacuum and collider-experiment interface teams.
These technological capabilities are crucial for the #HiLumiLHC upgrade for efficiency of the circulating beam, especially as it prepares to create more collisions at higher precision than ever before.
Here we see the gold and copper coating of beam position monitors (BPMs) for the #HiLumiLHC upgrade.
Each BPM undergoes a multi-step electroplating process, beginning with a thin gold strike to ensure proper adhesion of the 100-micron-thick copper layer.

Precision measurements are crucial for accelerator laboratories. For collisions to occur in the #LHC, the accelerator components must be aligned with a margin of error equivalent to the thickness of a single sheet of paper. The #HiLumiLHC will require even greater precision.
Groundbreaking calorimeter for the #HiLumiLHC
