265A Photomultiplier Tube (PMT) Base
- For use with 12-stage PMTs that fit standard 21-pin sockets
- Designed for fast-timing applications
- Excellent pulse fidelity for a wide range of signal currents
- High-impedance linear signal from dynode, and dc-coupled anode signal at 50-Ω impedance for timing
- Excellent for single-photon counting
- Magnetic shield available
The ORTEC Model 265A Photomultiplier Base is a mechanical assembly and a resistive voltage divider network, with appropriate capacitive decoupling, for operation of 12-stage photomultiplier tubes (PMTs). It is particularly suited to applications requiring fast timing or single photon counting.
