Engineers from the UK Atomic Energy Authority (UKAEA) have introduced a groundbreaking robotic device designed to inspect the intricate infrastructure of the Large Hadron Collider (LHC) at CERN. Named PipelNEER, this mouse-shaped robot aims to enhance the efficiency and safety of inspections across the collider’s extensive 17-mile (27 km) pipeline system.
The PipelNEER is a pioneering solution that utilizes artificial intelligence and specialized sensors to detect faults within the beamline pipes, which are crucial for the operation of the world’s most powerful particle accelerator. Operating under extreme conditions—temperatures nearing -455.8 °F (-271 °C) and ultra-high vacuum—the LHC’s infrastructure is complex and requires meticulous maintenance. Traditionally, accessing these pipes has necessitated extensive dismantling, a process that is both time-consuming and costly.
Addressing the Challenge
Within the LHC, the beamline pipes experience significant thermal cycling, causing them to expand and contract. This fluctuation can lead to slight bending in components, particularly the thin Radio Frequency (RF) elements responsible for maintaining electrical contact. Such distortions can jeopardize the reliability of the system, making regular inspections vital for safe and effective operations.
PipelNEER, measuring approximately 20 centimeters in length, is engineered to navigate through beamline spaces as narrow as 3.7 cm. Unlike conventional inspection tools, this innovative robot can travel up to 6 km on a single battery charge. As it traverses the beamline, PipelNEER captures high-resolution images of each plug-in module (PIM) and utilizes AI algorithms trained on actual LHC imagery to detect potential issues.
The robot is equipped with energy-efficient components and multiple safety systems to ensure reliable performance during its autonomous missions. Upon detecting a fault, PipelNEER can autonomously return to its starting point and report the exact location of the issue. This targeted approach allows engineers to concentrate on specific sections of the collider, significantly reducing the need for labor-intensive manual inspections.
Recognition and Future Testing
The collaborative efforts of UKAEA and CERN in developing the PipelNEER have been recognized with a ‘Highly Commended’ accolade at The Engineer’s Collaborate to Innovate (C2I) Awards. Ricky Sykes, Director of RACE at UKAEA, expressed pride in applying their robotics expertise to support CERN’s leading-edge experiments. “By combining our remote handling experience with CERN’s scientific excellence, we’re helping ensure the Large Hadron Collider operates safely and efficiently for years to come,” he stated.
Dr. Giuseppe Bregliozzi, a Beam Vacuum Operation Section Leader at CERN, added, “PipelNEER will transform how we inspect and maintain the LHC. It marks a major step forward in keeping our experiments running smoothly.”
Looking ahead, the PipelNEER robot is set to undergo performance trials spanning 37 miles (60 kilometers) in 2026. The final production units are anticipated to be manufactured by late 2026, with training for CERN operators scheduled for early 2027, preparing them for the robot’s deployment in critical inspection tasks.
The deployment of PipelNEER represents a significant advancement in the field of robotics and inspection technology, promising to enhance the operational integrity of one of the most ambitious scientific undertakings in modern history.
