The anode timing signal should be furnished to a fast discriminator such as the ORTEC Models 583B, 584, or 935, when using either NaI(Tl), liquid, or plastic scintillators. A Model C-25-12 50-Ω cable assembly is available as an accessory for this purpose.
For single-photon counting insert a fast amplifier, such as the Model VT120, between the anode output and the discriminator input.
The linear output from the ninth dynode is normally processed through an ORTEC Model 113 Scintillation Preamplifier and a shaping amplifier such as the ORTEC Models 460, 570, 572A, or 575A.
An ORTEC Model 218 Magnetic Shield
is recommended to reduce the interference from either the earth's magnetic field or from stray-magnetic fields from other equipment.
High voltage, at the level recommended by the manufacturer of the PMT, can be furnished from a high-voltage power supply such as the ORTEC Model 556. The mating cable, C-36-12, is also available for connecting the Model 265A to the Model 556; C-36-12 consists of 3.66 m (12 ft) of RG-59A/U 75-Ω cable with two SHV connectors assembled and ready to use.
