Machine learning methods for spectroscopic information recovery under ultrafast photon pileup
Jayson R. Vavrek, Thomas D. MacDonald, Yue Shi Lai
We present methods for recovering spectroscopic information from multiple concurrent photon interactions that would normally be lost due to pulse pileup. In particular, we focus on…

Transferability of data-driven optimization results across multiple pixelated CdZnTe spectrometers
Thomas D. MacDonald, Hannah S. Parrilla, Jayson R. Vavrek
Recent work by Vavrek et al. (2025) showed that machine learning methods can be used to exploit spatial patterns of performance variations within the highly-segmented H3D M400 gamm…

Data-driven optimization of pixelated CdZnTe spectrometers for uranium enrichment assay
Jayson R. Vavrek, Thomas D. MacDonald, Hannah S. Parrilla +3
In recent work [Vavrek et al. (2025)], we developed the performance optimization framework spectre-ml for gamma spectrometers with variable performance across many readout channels…
