The R6427 is a head-on photomultiplier tube with a bialkali photocathode, designed for scintillation counting and high energy physics applications. It features a 25 mm minimum effective area, a borosilicate glass window, and a 14-pin glass base with a supplied E678-14C socket. The tube has 10 dynode stages, an anode-cathode supply voltage maximum of 2000 V, and an average anode current limit of 0.1 mA. Spectral response ranges from 300 nm to 650 nm, with maximum response at 420 nm. Anode sensitivity is 500 A/lm at 2856 K, and the gain is 5.0 × 10^6. Anode dark current is up to 200 nA after 30 minutes in darkness. Pulse rise time is 1.7 ns, electron transit time is 16 ns, and transit time spread is 500 ps FWHM. Operating ambient temperature is from -30 °C to +50 °C, and storage temperature is from -80 °C to +50 °C.
