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

Part ID	Type	Driving Voltage	Gain	Spectral Range (nm)	Spectral Peak (nm)	Dark Current (after 30 min)	Rise Time (ns)	Transit Time (TT)(ns)	Transit Time Spread (TTS) (ns)
R1161	PMT - Head On	1000 V	1,0E+06	300 to 650	420	1-6 nA	2,5	27	2,8
R5505	PMT - Head On	1750 V	1,0E+06	300 to 1400	900	10 nA	3	23	1,5
