A Student’s Inspiring Visit to CERN: Exploring Particle Physics and Engineering at the Large Hadron Collider
Written by Bryn.
In the summer, I had the incredible opportunity to visit CERN, the European Organisation for Nuclear Research, in Geneva, Switzerland. This experience not only broadened my understanding of particle physics but also gave me a fascinating insight into the engineering marvels behind one of the world’s most advanced scientific research facilities. The highlight of my visit was a one-on-one interview with a CERN particle physicist, offering a unique glimpse into the cutting-edge research and teamwork that drive discoveries at this iconic institution.
Discovering the Engineering Behind the Large Hadron Collider
Upon arrival, I was immediately struck by the scale and complexity of CERN’s facilities. The sheer size of the Large Hadron Collider (LHC)—the world’s largest and most powerful particle accelerator—is awe-inspiring. During a tour with the physicist, I learned about the high-level engineering required to maintain the collider’s superconducting magnets at temperatures colder than outer space, enabling particles to accelerate to nearly the speed of light.
She explained how engineering and physics come together to achieve the incredible precision needed for experiments at CERN, reinforcing how essential cross-disciplinary collaboration is in modern science.
Behind the Scenes: Data Centres, Control Rooms, and Teamwork
What made the visit even more remarkable was the personal attention I received. The physicist kindly guided me through a one-on-one tour of the facility, explaining in detail the various experiments currently underway. We explored key locations within CERN, including the data centres and control rooms—the nerve centres where scientists and engineers monitor particle collisions and ensure smooth operations.
It was eye-opening to witness the immense amount of teamwork involved. Physicists, engineers, data analysts, and software developers all work together to push the boundaries of our understanding of the universe.
Hands-On Science: Building a Cloud Chamber
A particularly fun part of the day was participating in the “Build Your Own Cloud Chamber” activity. A cloud chamber is a simple yet effective tool for visualising the paths of ionising radiation through a medium such as alcohol vapour. Under the physicist’s guidance, I built my own and watched as tiny streaks revealed the tracks of subatomic particles.
This hands-on experiment made abstract physics concepts feel tangible. Seeing real particle tracks was a thrilling moment that gave me a deeper connection to the otherwise invisible world of quantum phenomena.
Conversations Over Lunch: Life and Research at CERN
The experience was not only educational but also social. I had lunch with the physicist and her colleagues, where I learned more about the diverse range of research projects at CERN—from analysing particle collisions to improving detector technologies.
Their passion for discovery was truly inspiring. I was especially struck by the collaborative, international environment at CERN, where experts from around the world unite to tackle some of the most fundamental questions in physics.
Overall, my visit to CERN was an unforgettable experience. It deepened my appreciation for the engineering and collaboration that underpin modern physics research. I left with a renewed curiosity about the universe and a better understanding of how scientific discovery relies on both technology and teamwork.
Each year, the Cheltonian Endowment Trust (CET) offers Travel Awards designed to foster independence and career preparation.
Applications are open to all Lower Sixth pupils, and awards are made following an interview process with a panel of three CET trustees. Typically, about 30 pupils apply for a grant and about half are successful. Destinations may be as far as India or Tanzania, or applications can also be for UK-based courses and experiences.
