abstract="The ultrafast mechanisms of radiation detection in granular YBaCuO films are studied in the wide wavelength range from millimeter to near infrared. With the rise of radiation frequency the Josephson detection at the grain boundary weak links is replaced by electron heating into the grains. This change occurs in the submillimeter wavelength range. Electron-phonon relaxation time $\tau$eph is determined by direct measurements and analyses quasistationary electron heating. Temperature dependence of $\tau$eph at T <= 40 K was found to be $\tau$eph \~{} T-1. The results show that detectors with the response time of few picoseconds at nitrogen temperature are attainable.",
