Experimental Setup for 21Na Measurements with BGO and Ge Detectors

This document outlines the schematic setup for measuring 21Na using advanced detection techniques. It includes Time-of-Flight (TDC) and Analog-to-Digital Conversion (ADC) components, configured to capture data from various detectors such as BGO and Ge. Key elements of the setup involve T-Si planes, dead-time measurements, and scaling modules for accurate timing and signal processing. The system also features triggers, clock management, and facilities for common dead time analysis, all aimed at enhancing the precision in particle detection and timing.
