The R1477-06 has a high sensitivity multialkali photocathode (even
higher than the R928). The spectral response covers a wide range
from 185 to 900 nm with a peak response at approximately 450 nm.
The R1477-06 also features the combination of high gain and low dark
current.
The R1477-06 is recommended for use in spectrophotometry and other low light level applications requiring super-high cathode sensitivity
from the UV to the near IR regions of the spectrum.

NOTES
A: Averaged over any interval of 30 seconds maximum.
B: The light source is a tungsten filament lamp operated at
a distribution temperature of 2856K. Supply voltage is
100 volts between the cathode and all other electrodes
connected together as anode.
C: Red/white ratio is the 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 B.
D: 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 conditions as Note B.
E: Measured with the same light source as Note B and with
the voltage distribution ratio shown in Table 1 below.
F: Measured with the same supply voltage and voltage dis-
tribution ratio as Note E after removal of light.
G: ENI is an indication of the photon-limited signal-to-noise
ratio. It refers to the amount of light in watts to produce
a signal-to-noise ratio of unity in the output of a
photomultiplier tube.

ldb = Anode dark current (after 30 minute storage)
in amperes
G = Gain
∆f = Bandwidth of the system in hertz. 1 hertz is
used.
S = Anode radiant sensitivity in amperes per watt
at the wavelength of peak response.
H: 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.
J: 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.
K. Also called transit time jitter. This is the fluctuation in
electron transit time between individual pulses in the
signal photoelectron mode, and may be defined as the
FWHM of the frequency distribution of electron transit
times.
L. Hysteresis is temporary instability in anode current after
light and voltage are applied.

Hysteresis = × 100 (%)
(1) Current Hysteresis
The tube is operated at 750 volts with an anode current of 1
micro-ampere for 5 minutes. The light is then removed from
the tube for a minute. The tube is then re-illuminated by the
previous light level for a minute to measure the variation.
(2)Voltage Hysteresis
The tube is operated at 300 volts with an anode current of
0.1 micro-ampere for 5 minutes. The light is then removed
from the tube and the supply voltage is quickly increased to
800 volts. After a minute, the supply voltage is reduced to
the previous value and the tube is re-illuminated for a
minute to measure the variation.
