Sydor’s Pulse Dilation PMT (PD-PMT) allows users to expand a signal, and essentially magnify time to enabled improved temporal resolution.
The 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. This PD-PMT offers extreme performance, but with the ease of simple and robust operation. The resulting expansion enables the use of inexpensive readout electronics for applications that otherwise would require expensive high-performance electronics. The PD-PMT brings new capabilities to Cherenkov measurements, gamma reaction history, time of flight, luminescence, and other experiments where a high temporal resolution window is required.
