The quest to unravel the deepest mysteries of the universe often requires pushing the boundaries of technology. This is exemplified perfectly at the Large Hadron Collider (LHC), a monumental scientific instrument situated along the border between Switzerland and France. The LHC’s 17-mile tunnel accelerates particles to near the speed of light, creating extreme conditions during collisions that produce significant radiation challenges for electronic components.
Traditional electronics cannot withstand the high-energy radiation generated in these environments, complicating efforts by CERN’s physicists to explore phenomena such as the Higgs boson. The niche requirement for radiation-resistant circuits typically doesn’t attract interest from major manufacturers. This gap has prompted academia to step up with innovative solutions.
At Columbia University, a team led by Peter Kinget has risen to this challenge. Their work resulted in the development of custom silicon chips specifically designed to withstand the LHC’s demanding environment. Known as analog-to-digital converters (ADCs), these chips play a crucial role in transforming the electrical signals from particle collisions into digital data. By leveraging commercially-available semiconductor processes validated by CERN for radiation resistance, the team introduced advanced circuit techniques that detect and correct errors in real-time.
Two notable chips have emerged from this project. The first chip, the trigger ADC, is designed to sift through vast amounts of collision data and identify events of scientific interest. Validated in 2022, it has been operational since. The second chip, the data acquisition ADC, is set to integrate into the upgraded LHC electronics, enabling even more precise measurements of collision signals.
These achievements are a product of collaboration between engineers and physicists from Columbia University and beyond, paving the way for new explorations of fundamental questions about the universe. As John Parsons from Columbia University emphasizes, cutting-edge instrumentation development is essential for scientific breakthroughs.
