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.

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.
