The Preamplifiers – Scintillation Detectors family is designed for the readout of scintillation-based detection systems used in nuclear and high-energy physics experiments. These preamplifiers combine low noise, fast response, and high rate capability to ensure accurate charge integration and precise timing extraction from photodetectors such as PMTs coupled to scintillators.
Based on charge-sensitive architectures, they convert detector current pulses into voltage signals proportional to the collected charge, providing stable energy outputs with wide dynamic range and selectable sensitivity. Dedicated fast outputs preserve the original signal shape for timing measurements, enabling simultaneous energy and timing processing within the same acquisition chain. Calibration inputs and flexible gain settings allow straightforward optimization across different detector types and experimental conditions.
