Pulse Dilation Photomultiplier Tube (PD-PMT)
Extreme Temporal Precision. Extended Diagnostic Range.
This device uses a custom circumferential photocathode pulser coupled to an expanded PMT tube to magnify the time resolution of our fastest 100 ps PMT to under 10 ps. This expanded time resolution is maintained even when using a relatively slow and less expensive oscilloscope readout system with only 2 to 6 GHz capability. The PD- PMT Tube offers extreme performance, but with the ease of simple and robust operation.
Key Benefits
- Unprecedented Temporal Precision
Allows users to have increased temporal response by applying unity temporal magnification. - Radiation‑Hardened Design
All-vacuum tube with magnetic confinement. Rugged alternative to CCD-based detectors.
Mission-Ready Configuration
Includes photocathode, mesh drift tube, 52 cm magnetically confined drift region, MCP detector, and high-speed ramp pulser. Fiber-optic trigger input ensures safe, remote operation. Accessory kits include vacuum interface hardware, mounts, shields, cabling, and alignment tools.
