Network Time Synchronization of the Readout Electronics for a New Radioactive Gas Detection System
In systems with multiple radiation detectors, time synchronization of the data collected from different detectors is essential to reconstruct multidetector events such as scattering and coincidences. In cases where the number of detectors exceeds the readout channels...
Electronics Upgrades to the Green Is Clean Phoswich Detector Systems and Programmatic Implementation at LANL – Phase II Completion – 18403
Los Alamos National Laboratory (LANL) radiological facilities produce low-density room trash that, in many cases, is not contaminated with radioactivity. It has been estimated that 50 to 90% of low-density room trash is free of radioactive contamination and eligible...
New Algorithms for Improved Digital Pulse Arrival Timing With Sub-GSps ADCs
The ability to measure pulse times of arrival with resolutions at or below 100 ps is becoming increasingly desirable in various fields, typically for signals originating from photon detectors such as photomultiplier tubes (PMTs) or silicon photo-multipliers. Achieving...
Network Time Synchronization for Detector Data Acquisition Electronics
Large scale nuclear physics experiments often use arrays of radiation detectors, which can be physically separated, for example in separate rooms or along a beamline. Time synchronization of the detector readout electronics, which is essential to detect related...
Status of Electronics Upgrades to the LANL Green Is Clean Phoswich Detector Systems – 16419
Los Alamos National Laboratory radiological facilities produce low-density room trash that, in many cases, is not contaminated with radioactivity. It has been estimated that 50 to 90% of low-density room trash is free of radioactive contamination and eligible for...
General Purpose Pulse Shape Analysis for Fast Scintillators Implemented in Digital Readout Electronics
Pulse shape discrimination applied to certain fast scintillators is usually performed offline. In sufficiently high-event rate environments data transfer and storage become problematic, which suggests a different analysis approach. In response, we have implemented a...
Development of a Phoswich Detector for Radioxenon Field Measurements
The Comprehensive Nuclear-Test-Ban Treaty Organization deploys a variety of radioxenon detection systems as part of its International Monitoring System to detect nuclear explosions. To achieve the high sensitivity required, the systems extract xenon from several cubic...
A Method to Correct Differential Nonlinearities in Subranging Analog-to-digital Converters Used for Digital γ-ray Spectroscopy
The influence on gamma-ray spectra of differential nonlinearities (DNL) in subranging, pipelined analog-to- digital converters (ADCs) used for digital gamma-ray spectroscopy was investigated. The influence of the DNL error on the gamma-ray spectra, depending on the...
Sources of Variability in Alpha Emissivity Measurements at LA and ULA Levels, a Multicenter Study
Alpha emissivity measurements are important in the semiconductor industry for assessing the suitability of materials for use in production processes. A recently published round-robin study that circulated the same samples to several alpha counting centers showed wide...
