Updates on MURAVES Project at Mt. Vesuvius

Abstract

The MUon RAdiography of VESuvius (MURAVES) project aims to use muography imaging techniques to study the internal structure of the summit of the Mt. Vesuvius, an active volcano near Naples, Italy. This paper presents recent advancements in both data analysis and simulation tools that enhance the quality and reliability of the experiments results. A new track selection method, termed the Golden Selection, has been introduced to select high quality muon tracks by applying a refined Chi2 based criterion. This selection improves the signal to background ratio and enhances the resolution of muographic images. Additionally, the simulation framework has been upgraded with the integration of the MULDER (MUon simuLation for DEnsity Reconstruction) library, which unifies the functionalities of pervious used libraries within a single platform. MULDER enables efficient and accurate modeling of muon flux variations due to topographical features. An agreement is shown between simulated and experimental flux map.
