Resumo
Neutrons can be detected indirectly through a nuclear reaction where the
products are ionizing radiation. Due to the shortage of 3He, most commonly
used element for such measurements, several studies are searching alternatives,
where the Gas Electron Multiplier (GEM) detector using a layer of 10B
as a neutron converter is a very promising option. The GEM detectors are
a type of Micro-Pattern Gaseous Detectors (MPGD), widely used in particle
tracking systems, as the Time Projection Chamber of the ALICE experiment
in the LHC-CERN, and proposed for many other applications, including neutron
detection. A common strategy to simulate this kind of detector is based
on two frameworks: Geant4 and Garfield++. The first one provides the simulation
of the nuclear interaction between neutrons and the 10B layer, while
the second allows the simulation of the interaction of the reaction products
with the detector gas leading to the ionization and excitation of the gas molecules.
Given the high ionizing power of this nuclear reaction products, a full
simulation is very time consuming and must be optimized to become viable.
We developed a fast simulator by means of parameterization strategy based
on these two frameworks that allowed us to generate enough data to study
an optimized version of this detector aiming for a better position resolution.
