NOTES

C:

F:

The light source is a tungsten filament lamp operated at a distribution temperature of 2856 K. Supply voltage is 150 volts between the cathode and
all other electrodes connected together as anode.
The value is cathode output current when a blue filter(corning CS 5-58 polished to 1/2 stock thickness) is interposed between the light source and
the tube under the same condition as Note A.
Measured with the same light source as Note A and with the anode-to-cathode supply voltage and voltage distribution ratio shown in Table 1 below.
Measured with the same supply voltage and voltage distribution ratio as Note C after 30 minute storage in darkness.
Those are test date when a signal from a central channel of 64 anodes is used, while all photocathode are illuminated by pulsed light source.
The rise time is the time for the output pulse to rise from 10 % to 90 % of the peak amplitude when the whole photocathode is illuminated by a delta
function light pulse.
The electron transit time is the interval between the arrival of delta function light pulse at the entrance window of the tube and the time when the
anode output reaches the peak amplitude. In measurement, the whole photocathode is illuminated.
Also called transit time jitter. This is the fluctuation in electron transit time between individual pulses in the single photoelectron event, and defined
as the FWHM of the frequency distribution of electron transit time.

REVISED POINTS
<From Ver.1 to Ver.2>
1) The length of assembly was changed from 31.7 mm

± 1.0 mm to 33.0 mm ± 1.0 mm.

2) The terminal connectors were changed from 32-pin type to 36-pin type.
3) The coaxial dynode output connector was removed.
4) Numbering of anode was changes from 1-1...8-8 to P1...P64.
5) The position of HV cable was moved to other side.

<From Ver.2 to Ver.3>
1) PMT length was changed from 14.7 mm

± 0.5 mm to 14.9 mm ± 0.5 mm.

2) The length of assembly was changed from 33.0 mm

± 1.0 mm to 33.2 mm ± 1.0 mm.

3) Other dimensional outline of assembly was changed accordingly.
4) The thickness of metal package was changed from 0.25 mmt to 0.5 mmt, then "

µ-METAL SHIELD" was removed.
