25 mm (1”) photomultiplier
9111B series data sheet
The 9111B is a compact 25 mm (1") diameter, end window
photomultiplier with plano-concave window, blue-green
sensitive bialkali photocathode and 10 high gain, high stability,
SbCs dynodes of circular focused design for fast timing. The
9111WB is a variant for applications requiring UV sensitivity.

The 9111B is the parent type. It meets the specification
contained in this datasheet. Variants are listed below with the
convention for deriving the type number that includes your
selection. Also we can select to different specification limits to
suit your particular application. For one-off requirements the
selection will change the B suffix to A, or for ongoing
requirements Electron Tubes will advise a 2 digit suffix after the
letter B that maintains the customers specific requirements.
