| Abstract | Due to the rapid progress of the LHC performance, it is essential to monitor the damage potential of the circulating beams. For this purpose, loss maps are done regularly during beam operation by intentionally inducing controlled beam losses. Loss map analysis is a fundamental tool to assess the performance of the LHC collimation system. Here, we further develop the available analysis tools by integrating new features in the existing framework, such as the possibility to normalize beam loss signals to the flux of lost particles or to the total power lost during the loss map. These methods were tested on measurements performed during Run 3 and used to evaluate and compare the performance between crystal and standard collimation, as well as to calibrate the BLM beam dump thresholds for a more efficient operation. We present a theoretical overview of the features, as well as some practical code examples. |
