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.

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.

GEM Detector Readout System for Transmission Measurements on the Vesuvio Instrument at ISIS
Nuclear Instruments designed the readout system for a novel 2D detector used for neutron transmission measurements on the VESUVIO experiment at the ISIS Facility (UK). The detector is based on a thick GEM and features 384 readout pads (channels). The readout architecture consists of a series of distributed boards, each equipped with a Kintex-7 FPGA implementing 64 TDCs with a resolution of 0.5 ns, double-hit resolution of 4 ns, and 64-bit timestamping. Each FPGA interfaces with four GEMINI ASICs, which provide the analog front-end processing.
