ITT F4000 (S50UVG) Ultra-Fast Vacuum Biplanar Phototube
Photodétecteur de rayons gamma
Gamma-Detektor

This is a biplanar phototube for applications that require fast response monitoring of high intensity radiation. With a rise time of less than 500 picoseconds, detailed examination across nine orders of magnitude can be made in the gigahertz range. With an S-5 cathode and associated scintillator, the F4000 is well suited to monitoring short bursts of gamma radiation.
