| Abstract | Monitoring the intensity of protons extracted from the CERN Super Proton Synchrotron )SPS) ring towards the North Area (NA) facility at a high rate is of utmost importance, with increasing challenges, for the the current facility operation, the ongoing NA consolidation, and the future Physics Beyond Colliders (PBC) projects. Various instruments are being developed to measure beam current fluctuations across a broad range of frequencies, from a few hundred Hz to several hundred MHz. This note is dedicated to discussing the design and initial implementation of a new Optical Trans-ition Radiation - Fast Spill Monitor (OTR-FSM). It outlines the constraints identified during the early design phase, the first upgrades performed during the 22-23 YETS, and the results obtained during the 2023 operational period. Finally, it offers an improvement proposal for the YETS 23-24 to address the obstacles encountered so far. |
