Resumen:

We installed a very sensitive solar neutron telescope at Mt. Sierra Negra (4,600 m above sea level) in Mexico in April, 2013. This new solar neutron telescope is four times more sensitive than the current solar neutron telescope at Mt. Sierra Negra, due to its high detection efficiency of neutrons. This project is called SciCRT (SciBar for the Cosmic Ray Telescope) . The data taking speed of the current system is limited to 1 kHz, although the expected count rate of background neutrons is 20 kHz. To reduce the data taking dead time, we started to develop a new system using SiTCP to replace the current system which uses traditional VME. SiTCP enables us to transfer high speed data from Field Programmable Gate Array to DAQ PC with Transmission Control Protocol. We could achieve the readout speed of 48 kHz in some specific condition, and we are continuing several tests to apply this new system to a more realistic experimental situation. In this paper, we will present details of the design of the new data taking system and several tests performed to achieve a fast readout. © 2013 Sociedade Brasileira de Fisica. All Rights Reserved.
