Critical Parameters
| Parameter | Description | Typical Value (Fast PTM) |
|---|---|---|
| Rise Time (TR) | The time interval between the arrival of photon at the cathode and the arrival of the amplified pulse at the anode | 0,05 (MCP) to 3 ns |
| Transit Time (TT) | The time interval between the arrival of photon at the cathode and the arrival of the amplified pulse at the anode | MCP:0,5 ns. PMT: 5-30 ns |
| Transit Time Spread (TTS) | Considered as the most important specification for time-resolved measurements; the timing variation due to the different geometric paths that the electrons can take from the cathode to the anode | MCP: 0,025 ns. PMT: 0,2-1,5 ns |
