| Category | Parameter | Specification / Description |
|---|---|---|
| General Information | Product Code | C14019-01 |
| Product Type | Voltage Divider Circuit (Bleeder Board) for Photomultiplier Tubes | |
| Description | A printed circuit board (PCB) with a pre-configured network of resistors to provide the correct graded voltage to each dynode of a PMT from a single high-voltage input. The -01 indicates a specific resistor ratio or connector type. | |
| Compatibility | Intended PMT Series | Likely designed for a specific PMT series (e.g., 2-inch diameter head-on tubes like R11256, R1250, or similar). The base PMT is NOT included. |
| Socket Compatibility | May be designed to integrate with a specific PMT socket (e.g., Hamamatsu E1198-XX series). | |
| Electrical | Divider Type | Standard (Linear) Divider or Zener-regulated Divider (for improved stability at high count rates). The -01 specifies the type. |
| Resistor Values | Precisely calculated values to achieve the recommended inter-dynode voltages for the target PMT. | |
| Ratio | Defined by the specific resistor network (e.g., optimized for 10-stage or 12-stage PMTs). | |
| Input Voltage | Designed for a specific HV range (e.g., -1000 V to -1500 V DC). | |
| Connectors | HV Input | SHV connector or solder terminal. |
| Anode Output | BNC connector (standard) or solder terminal. | |
| Intermediate Dynode Taps | May include taps for focusing electrode (F) or dynodes (Dy8, Dy9) for fast timing applications. | |
| Key Feature | Pre-assembled and tested, eliminating soldering errors and ensuring optimal PMT performance. | |
| Performance | Stability | Provides stable gain for the PMT when used with a stable HV power supply. |
| Current Handling | Designed to handle the average anode current of the compatible PMT without resistor drift. | |
| Mechanical | Form Factor | PCB board with mounting holes. Dimensions specific to the compatible PMT/socket assembly. |
| Material | FR-4 or other high-quality PCB substrate. | |
| Applications | Replacing homemade dividers, OEM instrument manufacturing, repair, and ensuring manufacturer-recommended performance from a PMT. |
