The results from studying the time characteristics (counting, amplitude distributions of single-electron pulses, spread of the signal propagation time (jitter) when exposed to radiation from picosecond diode lasers in the spectral range 405–780 nm) of high-speed photomultipliers FEU-175 and FEU-186 manufactured by AO Central Research Institute Electron (St. Petersburg). FEU-175 and FEU-186, respectively, are equipped with bialkali and multialkali photocathodes; their operating spectral range is 250–650 and 250–800 nm, respectively. Signal amplification is provided by a 14-dynode multiplication system, while the rise time of the PMT impulse response does not exceed 1.5 ns and the jitter is approximately 0.4 ns. PMT data can be used as photodetectors in single-quantum kinetic spectrometers with subnanosecond resolution and in other high-speed optoelectronic recorders.
