Socket Power Supply for Photomultiplier Tube (PMT)
The HPMA series is a reliable, high-performance power supply featuring a socket designed for 1-1/8 inch (28 mm) diameter side-on photomultiplier tubes (PMTs). The series includes two models, the HPMA-1NS-L2B and the HPMA-1N-L2B, both compatible with the Hamamatsu R928 PMT. The socket integrates a high-voltage power supply and voltage divider circuit, resulting in low noise and high linearity.
Additionally, the compact design incorporates a conventional bleeder circuit to enhance technological precision.
Technological precision is also achieved in this compact power supply with a conventional bleeder circuit.
FEATURES
- Designed for 1-1/8 inch (28 mm) side-on photomultiplier tubes (PMTs)
