R5560SE

128-channel 14-bit 125 MS/s digitizer with single-ended inputs and open FPGA architecture for customizable data acquisition.

R5560

128-channel 14-bit 125 MS/s digitizer with open FPGA and multi-detector support for large-scale experiments.

LEM - Low Energy Module

The Low Energy Module (LEM) is a compact, high-precision particle spectrometer developed for the NUSES satellite to detect low-energy protons and electrons in low Earth orbit. The detector employs a hybrid readout system combining silicon PIPS sensors and plastic scintillators with SiPMs, supported by a powerful onboard DAQ and FPGA firmware, enabling high-rate histogram and list mode acquisition.

ISIS HiFi muon spectromenter DAQ upgrade

As part of the ongoing enhancement of the HiFi spectrometer at ISIS, Nuclear Instruments integrated the DAQ121—our high-speed, 1 Gsps, 12-bit digitizer—into the data acquisition chain alongside the legacy TDC system. This hybrid configuration enables advanced digital discrimination of PMT signals and real-time pile-up deconvolution, increasing temporal resolution and system flexibility for high-rate muon experiments.

20-bit Interleaved ADC for Direct Sampling in X-ray Spectroscopy

A novel 20-bit interleaved SAR ADC architecture enables direct digitization of preamplifier signals in high-rate X-ray spectroscopy applications. It eliminates analog reshaping stages while achieving sub-150 eV resolution at MHz-level event rates. Designed around a Zynq SoC and tested with the ARDESIA detector, the system demonstrates a robust, low-noise digital pipeline tailored for synchrotron environments and pixelated SDDs.

SuperMuSR

As part of the Super-MuSR upgrade at the ISIS Muon Pulsed Facility, Nuclear Instruments developed advanced front-end electronics, including custom sensors and preamplifiers, and integrated our DAQ-121 digitizer—an 8-channel, 1 Gsps, 12-bit simultaneous sampling system—enhancing time resolution and data throughput for next-generation muon spectroscopy.

ASTRI

ASTRI Mini-Array is an INAF project to build a network of nine dual-mirror Cherenkov telescopes for gamma-ray astronomy. Located at 2400 m altitude in Tenerife, it will detect high-energy photons (1–300 TeV) from cosmic sources and enable precision measurements in stellar interferometry and cosmic ray physics.

FAMU Experiment @ RIKEN RAL

The FAMU experiment at the RIKEN-RAL muon facility aims to precisely measure the proton Zemach radius through detection of characteristic X-rays from muonic hydrogen. Nuclear Instruments developed custom electronics for the LaBr₃:Ce detectors, including innovative preamplifier circuits and a unique “4-1” SiPM readout architecture. These improvements significantly enhanced time resolution—critical for separating prompt and delayed signals—while maintaining excellent energy resolution in the 100–130 keV range.

i-Spector

PMT replacement based on a SiPM array with integrated power supply and Ethernet Remote Control

Pignoletto

Pignoletto aims to create a multiscale analysis system of the characteristics of the soils and the environment, based on the combination of geophysical field measurements with measurements obtained from airborne sensors, satellite information and proximity surveys.

R5560 Readout System for ESS-LoKI SANS

LoKI is a SANS instrument that will enable scientists to answer the challenging materials science questions of tomorrow in fields from health and aging, to sustainability and energy security. One of the first instrument concepts to be proposed and moved into construction, LoKI will be part of the early science programme at ESS.

Compact SiPM Detector upgrade for DIII-D

In collaboration with the Department of Physics at the University of Milano-Bicocca and the Institute for Plasma Science and Technology (CNR), Nuclear Instruments developed the electronics for a compact spectrometer optimized for the detection of hard X-rays generated by runaway electrons. Designed for integration with the Gamma-Ray Imager diagnostic on the DIII-D tokamak, the spectrometer features a high dynamic range (above 10 MeV), fast timing (≈70 ns FWHM), and real-time gain monitoring via an embedded LED. Stable performance under high counting rates (>1 MCps) makes this instrument well-suited for advanced plasma diagnostics.
