C7246 SERIES

PATENT

The C7246 series is a DA type socket assembly designed for 28 mm (1-1/8 inch) diameter side-on and head-on

photomultiplier tubes. The C7246 series socket assembly incorporates a voltage-divider circuit and a current-to-voltage

conversion circuit along with an amplifier that has a narrow but practical bandwidth (0 kHz to 20 kHz) to improve the

effective S/N ratio.

The C7246 series converts the low-level, high-impedance current of a photomultiplier tube into a low-impedance

voltage output by a factor of 0.3 V/ µA.

Since the C7246 series employs an active voltage-divider circuit, it ensures an excellent DC linearity at low power

consumption and a gain adjustment function that does not affect the frequency bandwidth of the amplifier.

FEATURES

aTo be also practicable even with ±5 V of input supply voltage except for narrow output range (2 V max).

bUse more than 600 V at negative high voltage input from view-points of output linearity, when giving more than 10 µA at signal input (anode out).

c"VR = MIN." means that the PMT gain is set to minimum gain.
