Resumen:

The SciCRT (SciBar for the Cosmic Ray Telescope) is a new project with a multi-purpose cosmic-ray experiment. The main aim of it is the measurement of solar neutrons to investigate ion acceleration process during the solar flare. It is important to investigate ion acceleration measuring the energy, the arrival time and direction of neutrons simultaneously because the propagation time of neutrons is determined by its energy. The SciCRT consists of 14,848 plastic scintillator bars (2.5 cm × 1.3 cm × 3 m) piled up to be used as a particle tracker. The detector is sensitive to the direction and the energy of neutrons recording the energy deposited inside each one of the bars crossed in its trajectory. The detector was used in an accelerator experiment (SciBooNE experiment) at Fermi National Accelerator Laboratory in USA. It was packed in February 2011 and sent to INAOE (Instituto Nacional de Astrofisica, Óptica y Electrónica) in Mexico. In INAOE the SciCRT with 5/8 of the total bars and anti counters recorded cosmic-ray data in November 2012 and February 2013. The detector was transferred to the top of Mt. Sierra Negra, 4,600 m above sea level, in April 2013. The first results of the operation of the experiment at the mountain are presented here. The current status and performance of the SciCRT will be discussed in detail. © 2013 Sociedade Brasileira de Fisica. All Rights Reserved.
