This document outlines the innovative setup of the Beam Shower Counters (L1 Trigger with E/W gap and minimum bias) and the Roman Pot Spectrometer used for beam loss measurements. Featuring three stations located 57 meters from the interaction point, the system includes three trigger counters and 240 channels for MIPs, achieving over 1000 counts. Additionally, the MiniPlug Calorimeter Tower geometry consists of 18+18 SumTowers and 84+84 Towers, and has been validated with cosmic-ray tests, demonstrating a performance of 120 pe/MIP.
