Examples of the ET Enterprises range of Voltage Dividers
Voltage dividers provide the voltage distribution required tooperate a photomultiplier.
C637 voltage dividers are supplied mounted on a B14B socket,either unflanged or flanged. It is soldered to the circuit boardfor direct connection to the photomultiplier. Conformal coatingis available on request.
Terminal posts T1 to T4 are provided for solder connection tohigh voltage power supply and signal cables. Cables with or without connectors, are available at additional cost. It is recommended that any electromagnetic screening around the photomultiplier tube is connected to photocathode potential via terminal post T5.
The C637 series of voltage dividers is designed for 30 mmdiameter, 11 stage photomultiplier tubes. Built onto an epoxy glass circuit board using a combination of surface mount and conventional components, the C637 series covers a range of applications with the following variants:
