The resources allowed unprecedented simultaneous solar observations with the 45 and 90 GHz polarimeters, the 0.2 and 0.4 THz solar telescope (SST), and the 30 THz detector (10 micron band), installed and operated at El Leoncito, Argentina Andes. Another 30 THz telescope was installed at Sao Paulo. New discoveries arose from these observations, compared to data at other energy ranges, radio, visible, UV, soft and hard X-rays. Spectral properties were found in GHz to sub-THz frequencies. Discovery of the importance sub-THz pulsations association to a CME launch time long before a very large flare. Similarities between solar flare particle accelerators to laboratory high energy accelerators have been proposed. A plasma oscillating mechanism explained the sub-second pulses repetition rates proportionality to mean fluxes observed in a impulsive sub-THz burst. Discovery of new intense 30 THz impulsive burst correlated to white-light flare, hard X-rays, H-alpha, UV and other radio emissions. The grant provided helpful complementary research and development for the completion of next generation of solar flare THz detectors, including the integration and final tests of the 3 and 7 THz solar flare photometers SOLAR-T space experiment, and the ground-based 0.85 and 1.7 THz telescope.
