The key high-speed characteristics of specialty ITT streak-tubes, photomultiplier tubes (PMTs), gated image tubes, and vacuum photodiodes are discussed. Type #F4157 and #F4157U streak-tubes are operable in the extraction mode with 20 ps FWHM resolution and in the normal swept-imaging mode with 100 ps FWHM resolution, and their spectral sensitivities are above 10 mA/W for the 435-870 nm and 325-830 nm wavelength ranges, respectively. Microchannel plate (MCP) photomultiplier tubes (MPMTs) are being made with single anodes, multiple anodes, and resistive anodes, and they have speeds-of-response which range from 460 ps FWHM for the #F4129 in an #F4545 coaxial output holder, to 0.5-1.0 MHz maximum pulserate for the #F4146M photon-counting position sensing PMT (PSP). Gated MCP image tubes (CITs) have shutter periods down to 1 ns or less for specially designed versions. The 18 mm and 25 mm active diameter MPMTs and CITs are available with either conventional or GaAs photocathodes. The vacuum photodiodes are capable of producing output rise-and-fall times less than 100 ps.
