*1:Vd is the AD bias voltage at the leakage current 1 µA. The voltage of Vb is form 300 V to 500 V.
*2:At the photocathode voltage of -8 kV and the AD bias voltage of Vb (breakdown voltage)-10 V.
*3:At the single photon state and the full illumination on photocathode, specifed as FWHM(Full Widh at Half Maximum).
These valves include the jitter of the electronics about 30ps.
*4:At 500 nm
The C12929 is a high voltage power supply unit for Hamamatsu R10467U/R11322U/H13223, Hybrid Photo-detector (HPD) series and its family products. The C12929 provides both photocathode high voltage and target avalanche diode reverse bias voltage which are required to operate HPDs. For the photocathode high voltage, the C12929 can supply up to -8500 V and ±500 V for the avalanche diode reverse bias voltage. User can control these voltages by using switches on the front panel of C12929 ,and inputting control voltages to the remote control connector on the backside of the C12929.
The C13265 is a high voltage power supply for HPD. This is the original equipment manufacturing version. The C13265 provides both photocathode high voltage and target avalanche diode reverse bias voltage which are required to operate HPDs. For the photocathode high voltage, the C13265 can supply up to -8500 V and +500 V for the avalanche diode reverse bias voltage. C13265 can not switch polarity of the output voltage for reverse bias voltage. User can control these voltages by inputting control voltages to the connector on the front panel of the C13265.
