A new type of picosecond streak image tube has been developed. The electron optical system of this tube consists of a curved photocathode, a curved mesh, a spherecal focous electrode and an anode cone. The deflector with ultroshort parallel plate construction is adopted. S20 photocathode is made on the Cu-Ni mesh substrate having surface resistivity Qf 300*Cland with transmissivity of 30% for white light. The measured photosensitivity is up to,140,11A/1m. The curved mesh of 50 lines/mm is fabricated by using special technique. P11 phosphor screen is deposited on a fibre faceplate having working area of P50 mm. The obtained static optimum spatial resolution is 40 1μm. The deflection sensitivity of the deflector is 4.2 cm/kv. The magnification of the tube is 2 and it is spatial distortion free. The dynamic measurements show that at present the temporal resolution reaches 2 ps and the useful dynamic range is greater than 256 for the temporal resolution of 10 ps. The slit streak image curvature phenomena has been eliminated.
