Obtaining the optimum polarization point in gas detectors with Bayesian optimization

Year: 2025

Type: article

Abstract: Some detectors, particularly gas detectors, have an optimum polarization point at which their efficiency increases, resulting in more stable measurements. Finding an optimal polarization point can be tedious in many cases, specially when it has to be calculated in situ and manually. In addition, this point can vary over time depending on the environmental conditions of the detector. This manuscript proposes the automatic calculation of this polarization point using a method based on Bayesian optimization . The validation of this method has been carried out first using theoretical polarization curves and then using the real polarization of one of the particle detectors that make up the CaLMa neutron monitor.
