	The precise knowledge of the transverse beam emittances on the different energy plateaus of the CERN Antiproton Decelerator (AD) ring is important for assessing the machine performance and beam quality. This paper presents a methodology for reconstructing transverse beam profiles from scraper measurements employing the Abel transform. The proposed methodology provides a precise, reproducible and user independent way of computing the beam emittance, as well as a useful tool to qualitatively track machine performance in routine operation. As discussed in this paper, its application has already been proven crucial for the operational setting-up of the stochastic cooling and for determining the proper functioning of the electron cooling in AD. It also opens up the possibility for detailed benchmarking studies of the cooling performance in different machine and beam conditions.

Future high-intensity fixed target experiments aim to advance this field further. This contribution highlights upgraded operational target systems, enhancing CERN’s physics endeavours.
