Abstract
In this work, we have explored a practical extension of the conventional light-shining-through-walls technique by making direct use of the high-intensity -ray beam available at a – collider. The energetic and highly collimated photon flux produced via inverse Compton scattering naturally provides an efficient axion-like particles production stage, while the addition of a regeneration region downstream enables a complete LSW configuration without introducing new experimental complexities. This approach, therefore, represents an experimentally simple and infrastructure-compatible method for enhancing laboratory sensitivity to axion-like particles (ALPs). Under conservative assumptions, we find that 1 year of operation can probe ALP–photon coupling down to 
for 
when an additional magnetic region is included upstream of the beam dump, improving upon previous laboratory LSW sensitivity by up to a factor of 4.
