Image-converter tubes and image intensifiers in CCD readout devices intended for picosecond recording systems

In the optical channel of picosecond recording system a set of cross-over image tubes and microchannel intensifiers were used together with either light sensitive cooled CCD-image sensor (520. JC pixels) or electron-bombarded CCD installed inside cross-over type image tube, or SIT-vidicon sensor. 4.5±0.5 Ps light pulses from YA1O3 :Nd laser at l.O8jum wavelength, and 2 Ps light pulses from AlGaAs/GaAs semiconductor laser at 850 nm wavelength were employed for comparative measurements of the recording system. It is shown that the electron-bombarded CCD matrix placed inside cross-over type image tube and matched through fibre optics window directly to pv-oo1 temporal-analysing image converter tube, provides the overall system spatial resolution of 25 line pairs/mm at 30% MTF, dynamic range of not less than 50 and input photocathode sensitivity about 2E-1O J/cm**2.
