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
