Status Report on Bertan CF4 Measurements and Magnet Performance Analysis

This report provides detailed electrical measurements from the Bertan CF4 apparatus, capturing current readings at various voltages across multiple configurations. Measurement results indicate variations in current between the West, East, North, and South detectors, specifically under conditions such as shorts and dead resistances. Additionally, it addresses issues related to the ramping of central magnets that may cause trips in different detector zones. For further details, all data is compiled on the provided web portal.
