The “Photomultiplier Tubes Catalogue” from Photonis Imaging Sensors includes a tube-type list and selection guide that details applications and characteristics. A section devoted to tube basics covers such areas as timing, linearity, stability, collection efficiency, the photocathode, the electron multiplier, and anode dark current and noise. Organized by tube diameter, the product range and data segment begins with a guide to choosing a tube, which includes information on gain, number of stages, response speed, and photocathode spectral sensitivity and size. Accessories such as sockets, Mumetal shields and voltage dividers are itemized, and numerous chart and diagrams are provided.
