HAMAMATSU R1464

PHOTOMULTIPLIER TUBE
R1464
High Anode Sensitivity at Low Supply Voltage
19mm (3/4 Inch) Diameter, 10 Stage, Head-On Type
185 to 850nm Response Multialkali Photocathode
The Hamamatsu R1464 is a 19mm (3/4") diameter, head-on type photomultiplier tube having a multialkali photocathode designed for
use in UV to near IR spectrophotometers and other analysis equipments where wide range response and high gain are of importance. The R1464 exhibits a high anode sensitivity at relatively low supply voltage by virtue of improvement in secondary emitting
surface, compared with the Hamamatsu R663 photomultiplier tube which has the same spectral response characteristic and mechanical specifications as the R1464.

NOTES
1: Averaged over any interval of 30 seconds maximum.
2: The Voltage distribution ratio is shown in Table 1 below.
3: The light source is a tungsten filament lamp operated at a distribution temperature of 2856K. The light input is 0.1 micro-lumen.
4: Under the same conditions as Note 3 except that the light input is 10-2
lumen and 150 volts are applied between cathode and all other electrode
connected together as anode.
5: Red/White Ratio is quotient of the cathode current measured using a red
filter (Toshiba R-68) interposed between the light source and the tube by
the cathode current measured with the filter removed under the same conditions as Note 4.
6: ENI is an indication of photon limited signal-to-noise ratio. It refers to the
amount of light in watts to produce a signal-to-noise ratio in unity in the
output of a photomultiplier tube. In this catalog the value of peak wavelength is described. ENI is given by the following formula:

where q = Elementary charge (1.60 × 10-19 coulomb)
ldb = PMT anode dark current (after 30 minute storage) in amperes
G = PMT gain
∆f = Bandwidth of the system in hertz. In this catalog, 1 Hz bandwidth is
used.
S = Anode radiant sensitivity in amperes per watt at the wavelength
of peak response.
7: The rise time is the time for the output pulse to rise from 10% to 90% of
the peak amplitude when the entire photocathode is illuminated by a delta
function light pulse.
8: The electron transit time is the interval between the arrival of a delta function light pulse at the entrance window of the tube and the time the output
pulse reaches the peak amplitude. In measurement the entire photocathode is illuminated.
