Product catalog summary

Specifications:
The document details the specifications of the R14755U-100 photomultiplier tube, which is housed in a metal package (TO-8 type). It features a high-speed response of up to 800 MHz and is compact and lightweight. The spectral response ranges from 300 to 650 nm, with a peak sensitivity wavelength of 400 nm. The photocathode material is SBA, and the window material is borosilicate glass. The effective area is 8 mm, and it includes 6 dynode stages. The gain is 2.5 × 10⁴, with a rise time of 400 ps. The operating and storage temperature ranges are both -30 to +50°C, with no condensation allowed.

Features:
The photomultiplier tube is suitable for optical communication and mass spectrometry applications.

Maximum Ratings:
The supply voltage is 1000 V, with an average anode current of 0.1 mA. The voltage distribution ratio across the electrodes (K, Dy1-Dy6, P) is uniform.

Figures and Diagrams:
Figure 1 illustrates the time response with a full width at half maximum (FWHM) of 680 ps, a rise time of 400 ps, and a fall time of 420 ps. Figure 2 shows the typical spectral response, and Figure 3 depicts the gain as a function of supply voltage. Figure 4 provides the dimensional outline and basing diagram, indicating the internal connections and effective area.
