| The determination of neutron induced cross sections demands a precise knowledge
of the neutron beam profile. Different experiments have adopted different detectors.
At the n_TOF facility [1] the neutron beam profile is determined with a MicroMegas
detector equipped with a neutron to charged particles converter, allowing
to exploit ionization for detection purposes.
This report summarizes the results obtained in 4 years of operation of the “XYmicromegas”
detector, as well as in the test of the “PXMG-micromegas” detector at
the n_TOF facility at CERN.
A brief introduction about micromegas detectors and the differences between
bulk and microbulk technology is first reported, followed by simulations allowing
to draw considerations to establish the best image reconstruction method. The description
of the two detectors and the data analysis succeed in chronological order. |
