An improved solar neutron telescope installed at a very high altitude in México

The detection of solar neutrons on the Earthʹs surface provides us with important information on the particle acceleration mechanism to high energies at the solar surface. In order to understand the acceleration mechanism of ions at the solar surface, it is essential to measure the energy of solar neutrons. A new detector that can measure the energy and arrival direction of neutrons was constructed on the Sierra Negra Volcano at an altitude of 4580 m a.s.l., in Mexico. In this paper we describe the scientific purpose of the experiment, details of the detector characteristics, numerical simulations carried out to estimate its sensitivity and an electronic novelty used for the DAQ. We also present some of the data obtained at the Sierra Negra station.
