CMS

On June 19, scientists at the CMS experiment at CERN’s Large Hadron Collider published their 1,000th paper. The monumental achievement reflects an incomparable contribution to humanity’s understanding of the universe — and it’s just the beginning.

CMS has reached a momentous milestone by submitting its 1,000th paper for publication. In doing so, CMS became the first experiment in the history of HEP to reach this outstanding total of papers.

At the core of the mammoth detector assemblies and snugly surrounding the beam pipes are arrays of silicon sensors, which provide detailed patterns of interactions to micron-level precision, with subnanosecond timing and low mass. Research and development to improve the characteristics and develop better silicon detectors with the use of new technologies continue as we upgrade the existing detectors for better performance and develop designs for experiments at future generations of accelerators.

At Fermilab we mentor postdocs to become full-fledged scientists, supporting both the scientific development and the career advancement of postdocs so they can lead our field into the future. The postdoc mentoring program in the CMS Department has served as a model for similar programs throughout the lab. It relies on three basic elements to guide the postdoc to success: a balanced and ambitious research plan, a personal team of supporting scientists, and regularly scheduled mentoring events.

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.

For Reham Aly from Egypt, now a graduate student on CMS at the University of Bari, Italy, this was the first visit to the United States and Fermilab. She had been invited to come to work at the Fermilab LHC Physics Center for two months. Another student, Angela Taliercio, an Italian working on her Ph.D. at the University of Louvain, Belgium, had visited the LPC in 2018. The rewarding experience she had, she says, made her want to come back. Reham and Angela spent staggered two-month periods at Fermilab, from October to December 2019.

Those who study particle physics will find that every step of the journey offers a new perspective and new set of responsibilities. Symmetry chats with scientists working at the Large Hadron Collider to hear about differences between seven different rungs on the academic career ladder.

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.
