Resumen:
We present the capabilities and bases for a new instrument for neutrino detection using CCDs. Improvements in the CCDs fabrication processes has allowed the development of devices with larger masses (1g to 10g are available nowadays), which together with other good features such as their extremely low energy threshold ( 7eV RMS) and their good spatial resolution (15um), makes them a perfect candidate for neutrinos detection. This new technique opens a new window in neutrino detection because it allows the construction of small size neutrino detectors where the reduction in the expected event rate because of the smaller volume is fully compensated by the detection of additional very low energy events. The poster is intended to cover the mayor features and capabilities of scientific CCDs, the relevant physics involved in the neutrino detection, and a full explanation of the complete neutrino detection system being assembled at Fermilab, which is planned to be tested in a nuclear reactor by the middle of the year (2013). For this test, the instrument will be running at the Angra Nuclear Power Plant in Brazil.
