The Preamplifiers – Detectors family provides a comprehensive set of front-end solutions for reading out a wide range of radiation and particle detectors, including silicon and diamond sensors, photodiodes, scintillators, neutron tubes, and large segmented arrays. These modules convert detector charge or current signals into low-noise voltage outputs while preserving timing and energy information, ensuring optimal coupling with shaping amplifiers, discriminators, and digitizers.
The family spans single-channel to high-density multi-channel systems, with architectures optimized for applications such as spectroscopy, fast timing, position-sensitive neutron detection, and large-area detector arrays. Solutions include charge-sensitive, transimpedance, and wideband preamplifiers with configurable gain, bandwidth, and biasing options. Many units integrate programmable parameters, differential signaling for noise immunity, and support for remote control and long-distance detector cabling. Designed for demanding environments—including high radiation, vacuum systems, and high counting rates. These preamplifiers deliver stable operation, low equivalent noise, and flexible integration into modern DAQ chains.
