Abstract:
Beam Intercepting Devices (BIDs) play a vital role in any accelerator complex. They are responsible for producing secondary particles – such as neutrons, electrons, pions, anti-protons and kaons – protecting sensitive equipment, and safely handling the disposal of powerful, high-intensity beams. Designing and operating these components requires expertise across multiple physics and engineering disciplines. Their lifespan can vary dramatically, lasting anywhere from a few weeks to several decades, depending on factors like material degradation, structural wear, and accelerator upgrades.
In this contribution, we invite you on a journey through the lifecycle of BIDs – from initial concept to decommissioning. We will explore the design principles and technical choices that shape these components, emphasizing the multidisciplinary collaboration necessary to push technological boundaries. Drawing on past experiences, we will discuss key lessons learned in developing devices that can withstand ever-increasing beam intensities and energies, ensuring the success of both current and future accelerator systems.
From CERN’s perspective, we will highlight the importance of fostering diverse and inclusive teams to tackle these complex challenges. Several critical components at the heart of approved flagship projects – such as the High-Luminosity LHC upgrade and the upcoming High Intensity ECN3 / Beam Dump Facility – will be examined. Examples will also be given for specific CERN’s programs relevant for the audience, such as n_TOF and antiproton physics at AD/ELENA.
Looking ahead, we will also consider the challenges of beam interception for future initiatives, such as the Future Circular Collider and the Muon Collider.
