Structure of the partitioned target (a) and the electronics system (b).

Caption

Part (a) shows the partitioned target for simultaneous measurement of 235U and 238U: an 80 µm-thick aluminum substrate (32 mm diameter) divided into four quarter-circle regions (15 mm radius), with 235U and 238U deposited diagonally (99.9% purity, 8% thickness uniformity) and polyethylene on the back for recoil proton detection. Part (b) depicts the electronics system, consisting of a front-end data acquisition module (6U chassis, 128-channel differential inputs) and a back-end control system. The LabVIEW-based software enables real-time monitoring and data decoding, with a low noise level (0.6 mV) and dynamic range of 3000:1, supporting 50 MS/s sampling with 14 bits
