NOTES
A This is defined at 10 % to 90 % of full pulse height.
B Transit Time Spread (T.T.S.) is the fluctuation in transit time among individual pulses and specified as an FWHM (full width at half maximum) with the
incident light having a single photoelectron state.
C Two microchannel plates (MCPs) are incorporated as a standard but we can provide it with either one or three MCPs as an option depending upon your request.
D This is specified under the operating conditions that the repetition rate of light input is 100 Hz or less and its pulse width is 70 ps or less.
E This is based on R5916U-50. All other types (suffix number 51, 52 and 53) have different characteristics based on photocathode sensitivity and anode dark
counts.
F The light source used to measure the luminous sensitivity is a tungsten filament lamp operated at a distribution temperature of 2856 K. The incident light
intensity is 10-4 lm and 20 V is applied between photocathode and all other electrodes shorted as an anode.
G This is specified at a duty cycle of 1 %.
H This is the mean time difference between the 10 % and 90 % amplitude points on the output waveform under full photocathode illumination.
I This is the mean time difference between the 90 % and 10 % amplitude points on the tailing edge of the output waveform under full photocathode illumination.
J I.R.F. stands for Instrument Response Function which is a convolution of the δ-function (H(t)) of the measuring apparatus and the exciation function (E(t)) of
a laser. The I.R.F. is given by the following formula: I.R.F. = H(t)∗ E(t)
K We specity the I.R.F. as an FWHM of the time distribution taken by using the measuring apparatus in Figure 7 that is Hamamatsu standard I.R.F. measuring
set-up. It can be estimated by the following equation: (I.R.F. (FWHM))2 = (T.T.S.)2 + (Tw)2 + (Tj)2
where Tw is the pulse width of the laser and Tj is the time jitter of all equipments used in the measurement. An I.R.F. is provided with the tube.

R5916U-50 will be provided in a "normally off" mode configuration. It will be gated "on" only when the gate input pulse (+10 V to +20 V)
is applied and gated "off" when it is grounded or left in open.
However, we can also provide this device in a "normally on" mode configuration which can be operated under the same operating
conditions above to give inverse performance. Please specify if you require a "normally on" mode configuration when placing an order.

FUNDAMENTAL OPERATING PROCEDURE
1) A general set-up for R5916U-50 is shown at right.
This is to perform a photon counting with gating function
and to detect weak light generated from the samples by the
laser excitation.
2) The pulse generator used in this set-up produce an output
having +10 V in height and adjustable width which you require. It also produces a trigger signal synchronyzing an
output pulse to the laser output. The R5916U-50 is in gate
off mode in the beginning to prevent unwanted signals
caused by the laser light or some scattered light which may
strike the photocathode directly.
3) The pulse generator required for gating function is very
simple. The required specifications for the pulse generator
is as follows:
a. Output voltage is +10 V to +15 V.
b. Pulse width is just what you require (between 5 ns and
10 µs).

EXAMPLE OF APPLICATIONS
ENVIRONMENTAL MONITORING
This is an example of LIDAR (Light detection and ranging)
application where our gateable MCP-PMT has been used.
The sketch at right shows a LIDAR system which includes
a picosecond laser, electronics (gate driver), optics, computer and sensor (gateable MCP-PMT). This system is to
investigate the distribution of planktons in the ocean for
pollution monitoring.
The laser light irradiates sea water and generates some
scattered light due to contaminated water and fluorescence due to chlorophyll in planktons. By detecting these
emissions, a distribution of quantative and qualitative informations on these objects can be obtained. However, there
are enormous back ground emissions due to reflections of
the laser light off of the water's surface as well as from
particles in an air or some unknown materials in the
ocean. Sun light is also a source of back ground if the experiment has to be performed in day time.
In this application, fast gating function is very effective to
minimize the back ground noise. The tube is gated on only
during the time when essence emissions arrive at the detector.
The switching ratio characteristics are also very important
to help minimize the noise. The R5916U-50 series tubes
are superior on both characteristics.

Laser Satellite Ranging system b)
SATELLITE LASER RANGING (SLR)
This is also an example of a LIDAR application where the
gateable MCP-PMT has been used to measure the distance between the observatory and a satellite.
The operating principle is that a satellite is irradiated by
the fast laser pulse and then a reflected light is directed to
the detector through the optics placed on the ground. The
time interval of the signals from the source to the detector
in the system is the time of flight (TOF) from the observatory to the satellite and can be converted into a distance
between them.
This entire system consists of fast laser, optics, electronics, gate driver and detectors. The data taken by experiments with this system are also utilized for geodesy or
plate motion analysis on a world-wide level.
Because of the improved timing characteristics with
R5916U-50 series, more precise measurements can be
expected.

PRECAUTIONS FOR PROPER OPERATION
1. The photomultiplier tube (PMT) in this data sheet is a glass product under high vacuum. Excessive pressure or shocks to the tube
from the surroundings could cause a permanent damage. Please pay special attention on insuring proper handling.
2. Do not expose the photocathode to direct sunlight and any light stronger than the room light even during of no operation.
3. Do not supply any voltage higher than specified. Also make sure the output current does not exceed the maximum current specified.
4. This device is very sensitive even with weak light input. When applying high voltage to the tube, gradually (ideally 100 V step) and
carefully increase the voltage while monitoring the output using a current meter or oscilloscope (if the PMT has multianodes,
please make all the anode summed when monitoring). Also make sure before use that the polarity of the applied voltage is correct.
5. Never touch the input window with your bare hands. In case the window contaminated by dust or grease, wipe it off using alcohol
and a soft cloth or dust free tissue.
6. Do not remove any input or output cables when high voltage is applied.
7. Do not place any objects of ground potential closer than 5 mm to the photocathode window when negative high voltage is applied
to the photocathode. It could generate extra noise and damage the photocathode permanently.
8. Do not operate or store in a place of unspecified temperature and humidity.
9. If the tube won't be used with a cooler, it is recommended to leave the tube in darkness (your instrument without any input light) for
30 minutes or so before start any measurements because it occasionally takes a little while until its dark noise settles down.
WARRANTY
The detectors indicated in this data sheet are warranted to the original purchaser for a period of 12 months following the date of shipment. The warranty is limited to repair or replacement of any defective material due to defects in workmanship or materials used in
manufacture.
1. Any claim for damage of shipment must be made directly to the delivering carrier within five days.
2. Customer must inspect and test all detectors within 30 days after shipment. Failure to accomplish said incoming inspection shall
limit all claims to 75 % of invoice value.
3. NO credit will be issued for broken detector unless in the opinion of Hamamatsu the damage is due to a manufacturing defect.
4. NO credit will be issued for any detector which in the judgement of Hamamatsu has been damaged, abused, modified or whose
serial number or type number have been obliterated or defaced.
5. NO detector will be accepted for return unless permission has been obtained from Hamamatsu in writing, the shipment has been
returned repaired and insured, the detector is packed in their original box and accompanied by the original data sheet furnished to
the customer with the tube, and a full written explanation of the reason for rejection of detector.
