Description:
he MUon RAdiography of VESuvius (MURAVES) project aims at the study of the
summital cone of Mt. Vesuvius, an active volcano near Naples (Italy), by measuring its density
profile through muon flux attenuation. Its data, combined with those from gravimetric and seismic
measurement campaigns, will be used for better defining the volcanic plug at the bottom of the
crater. We report on the development of an end-to-end simulation framework, in order to perform
accurate investigations of the effects of the experimental constraints and to compare simulations,
under various model hypotheses, with the actual observations. The detector simulation setup is
developed using GEANT4 and a study of cosmic particle generators has been conducted to identify
the most suitable one for our simulation framework. To mimic the real data, GEANT4 raw hits
are converted to clusters through a simulated digitization: energy deposits are first summed per
scintillator bar, and then converted to number of photoelectrons with a data-driven procedure.
This is followed by the same clustering algorithm and same tracking code as in real data. We
also report on the study of muon transport through rock using PUMAS and GEANT4. In this
paper we elaborate on the rationale for our technical choices, including trade-off between speed
and accuracy. The developments reported here are of general interest in muon radiography and
can be applied in similar cases.
