Emulator-based Bayesian inference on non-proportional scintillation models by compton-edge probing.

Scintillator detector response modeling has become an essential tool in various research fields such as particle and nuclear physics, astronomy or geophysics. Yet, due to the system complexity and the requirement for accurate electron response measurements, model inference and calibration remains a challenge. Here, we propose Compton edge probing to perform non-proportional scintillation model (NPSM) inference for inorganic scintillators.

Recent developments at the Calibration Laboratory for radiation protection instruments and dosemeters of the Paul Scherrer Institute.

The Calibration Laboratory of the Paul Scherrer Institute is responsible for the calibration and verification of radiation protection instruments and dosemeters for internal as well as external customers, such as nuclear power plants and hospitals. The Laboratory is authorised by the Federal Institute of Metrology METAS to perform legal verifications and is accredited as an inspection body, according to ISO 17020, and as a calibration laboratory, according to ISO 17025 by the Swiss Accreditation Service. In addition to routine activities (e.

Comparison of optimization techniques for the Monte Carlo simulation of clearance monitors.

In this work, simulations of the clearance monitor HWM-1800 (Ludlum GmbH, Hamburg) with the Monte Carlo (MC) code FLUKA were performed and optimized. Nowadays, clearance monitors are being widely implemented for decommissioning activities in nuclear reactors and particle accelerator facilities. For every situation, a different calibration is typically needed, depending on the material composition of the samples to be released, their volume and the expected radionuclides.
