130 mm (5") photomultiplier
9823B series data sheet
1 description

6 characteristics

The 9823B is a 130mm (5”) diameter end-window
photomultiplier with blue-green sensitive bialkali photocathodeon a plano-concave window. It has 14 BeCu dynodes of linear
focused design for good linearity and timing. The 9823QB is avariant for applications requiring uv sensitivity.

Characteristics contained in this data sheet refer to divider B
unless stated otherwise.

The 9823B meets the specification given in this data sheet.
You may order variants by adding a suffix to the type number.
You may also order options by adding a suffix to the typenumber. You may order product with specification options
by discussing your requirements with us. If your selection
option is for one-off order, then the product will be referred toas 9823A. For a repeat order, ET Enterprises will give theproduct a two digit suffix after the letter B, for example B21.
This identifies your specific requirement.
