From CERN Courier, March 23, 2020: A quadrupole magnet for the High-Luminosity LHC has been tested successfully in the U.S., attaining a conductor peak field of 11.4 tesla — a record for a focusing magnet ready for installation in an accelerator. The device is based on the superconductor niobium-tin and is one of several quadrupoles being built by U.S. labs and CERN for the HL-LHC, where they will squeeze the proton beams more tightly within the ATLAS and CMS experiments to produce a higher luminosity.
Fermilab, Brookhaven National Laboratory and Lawrence Berkeley National Laboratory have achieved a milestone in magnet technology. Earlier this year, their new magnet reached the highest field strength ever recorded for an accelerator focusing magnet. It will also be the first niobium-tin quadrupole magnet to operate in a particle accelerator — in this case, the future High-Luminosity Large Hadron Collider at CERN.
What if you want to capture an image of a process so fast that it looks blurry if the shutter is open for even a billionth of a second? This is the type of challenge scientists on experiments like CMS and ATLAS face as they study particle collisions at CERN’s Large Hadron Collider. An extremely fast new detector inside the CMS detector will allow physicists to get a sharper image of particle collisions.
The USCMS collaboration has received approval from the Department of Energy to move forward with final planning for upgrades to the giant CMS particle detector at the Large Hadron Collider. The upgrades will enable it to take clearer, more precise images of particle events emerging from the upcoming High-Luminosity LHC, whose collision rate will get a 10-fold boost compared to the collider’s design value when it comes online in 2027.
The Large Hadron Collider is the world’s largest particle accelerator, known mostly for its discovery of the Higgs boson. The LHC will run for another two decades and will collect an enormous amount of data. In this 11-minute video, Fermilab scientist Don Lincoln explains how Fermilab is heavily involved in the upgrades required to make both the accelerator and the CMS detector a physics discovery powerhouse for the foreseeable future.
In his doctoral thesis, Todd details a method for data analysis in a way that minimizes a source of bias in some particle physics experiments. By analyzing information from two distant detectors simultaneously rather than sequentially, he incorporated the lack of precision knowledge in both detectors. A University of Cincinnati graduate, Todd used data from Fermilab’s MINOS and MINOS+ experiments, and his analysis can be applied in other neutrino research as well.
The year 2018 will be remembered as a very eventful year for CMS as a whole and especially for the Fermilab group. Thanks to excellent accelerator performance, the LHC delivered much more proton-proton collision data than anticipated, making the LHC Run 2 a very successful data-taking period. Being at the very core of the detector operations and computing, the Fermilab group was key in ensuring that a large and high quality data set was collected for searches and precision measurements.
