DESCRIPTION:Muography is an imaging technique used to study large structur
 es such as buildings\, volcanoes\, and pyramids. This thesis was conducted
  as part of the LouMu collaboration\, which seeks to test muography for th
 e first time in Portugal by applying it to the well-known environment of t
 he Lousal mine and evaluating its potential and sensitivity for future app
 lications.Transmission muography\, as the name suggests\, analyzes the tra
 nsmission of the flux of cosmic ray muons through an object to study it. T
 his is a promising technique as it utilizes a natural and non-perturbative
  flux.This thesis aims to provide a systematic account of the knowledge ga
 ined through muography in the Lousal mine. We collected data using a muon 
 telescope\, an apparatus designed to detect muons and determine their traj
 ectories. Our muon telescope recorded data from two different positions wi
 thin an old Explosive Storehouse in the mine\, intersected by a geological
  fault\, which was our target for muography. We produced 2D muography imag
 es\, and our ultimate goal is to combine these results from the two positi
 ons to create a 3D reconstruction of the mine.In this work\, we present th
 e images obtained so far and explain how we developed a function to descri
 be the muon telescope’s efficiencies.The function showed promise with si
 mulation\, but the results obtained with data still need improvement. We g
 ained valuable insights from this work\, and in the future\, we intend to 
 explore further the function&#x27\;s applications.
