Introduction
This catalog provides the latest information for Hamamatsu ruggedized high temperature photomultiplier tubes
ranging in diameter from 13 mm (1/2") to 51 mm (2"). All listed tubes employ high temperature bialkali photocathode that feature stable operation and long life at temperatures up to 90 °C, 175 °C or 200 °C. The electrode supporting structures have been designed so that tubes can be used in severe environments such as
may be found in oil well logging, geological exploration, and aerospace applications.
If you do not find the tube that meets your needs in this brochure, we will be pleased to custom produce a tube
or assembly for your unique requirements. We offer a wide variety of complete assemblies of tubes, sockets,
voltage dividers and tube shields which have been quality tested to assure reliable operation.
Applications
●Oil well logging (Wireline, MWD and LWD)
●Geological exploration
●Gauge meter
●Aerospace research

Figure 7 shows the variations of P.H. (pulse height) and Figure 8 shows P.H.R. (pulse height resolution) as a function of the ambient temperature.
These degradations are due to performance changes in the photomultiplier tube and efficiency losses in the crystal at high temperature.
Both parameters recover close to their initial values when tubes are returned to room temperature.
P.H.R. (pulse height resolution) characteristic of a PMT may be changed by the emission efficiency of scintillator used.
This data is taken with the scintillator 1"×2" NaI(TI) for R1288A, R1288AH, 0.75"×1.5" NaI(TI) for R3991A, R3991AH.

1-2. LLD during plateau measurement
This section describes the LLD (lower level discriminator) that should be set to make plateau measurements.
First, let us calculate the charge amount per pulse that is output from the PMT.
The number of photons emitted from a NaI(Tl) scintillator for high temperature and rugged environments is usually about 15 photons
per 1 keV of gamma-ray energy.
If using 137Cs (gamma-ray energy 662 keV), the number of emitted photons will be about 10,000. It is simply calculated by 662 × 15.
If the PMT is used with a 137Cs radiation source, the charge amount per pulse of the PMT is obtained as follows:
N×
×
×
× e = 10,000 × 0.15 × 0.8 × 5 × 105 × 1.6 × 10-19
= 100 pC
N : Number of photons emitted from scintillator per event
: Photocathode quantum efficiency (assumed to be 15 % at room temperature)
: PMT collection efficiency (assumed to be 80 %)
: PMT gain
e : Electron charge
As calculated above, the charge amount per pulse obtained using the 137Cs (662 keV) is about 100 pC.
The estimated charge amount obtained under the conditions at 175 °C will therefore be about 50 pC which is approximately half the
charge at room temperature (See Fig. 7 on page 22).
Based on these, the LLD should be adjusted to an optimal level, however, in view of the decrease in output during high temperature
operation, it is preferable that the LLD be set so that a plateau region can be obtained at a voltage lower than the rated voltage.
For general characteristics when LLD = 1.5 pC, refer to Figures 9 to 11.
Since the PMT gain and the emission intensity of scintillators differ from product to product, we advise adjusting the LLD setting as
needed to match the actual usage conditions so that the plateau region can be obtained below the rated voltage.
When setting the LLD, we suggest using a capacitor with a known capacitance and a pulse generator in order to calibrate by using the
pulse output from the capacitor.

Plateau measurement is usually performed by Hamamatsu with
a combination of a 137Cs radiation source and an NaI(Tl) scintillator, which serves as the light source. However, pulsed light
from a blue LED can also be used to evaluate plateau characteristics of the photomultiplier tube. Advantages of using a blue
LED is that decreasing of the emission efficiency of NaI(Tl) scintillators over time can be eliminated. In addition, the LED is set
outside the temperature-controlled chamber so it is not exposed
to high temperatures during measurement. This means that inherent characteristics of photomultiplier tubes can be measured.
Furthermore, plateau measurement using scintillators often requires a large number of scintillators and also extra processes
for measurement setups. This results in more work and increased cost in order to supply customers with plateau measurement data. Using blue LEDs allows simultaneous measurement of many photomultiplier tubes and supplying data with a
minimum cost increase.
Figures 14 and 15 show comparisons of plateau length data
measured using scintillators and blue LEDs. As can be seen,
this data shows a good correlation. The block diagram of the
test using a blue LED is also shown in Figure 13.

3. Technical information of
photomultiplier tube assemblies
3-1. Count rate characteristics
Power consumption is limited in oil well logging equipment.
The voltage divider circuit for operating the photomultiplier tube
must have low power consumption. A common method to lower
power consumption is to use a high resistance to limit the voltage divider current. However, such a design causes deviation in
photomultiplier tube gain when operated at a high count rate.
An active divider circuit is effective in solving this problem. Fig-
ure 1 shows count rate characteristics of a R1288A photomultiplier tube measured with active divider circuits of different base
resisters (1R=2 MΩ, 1R=100 kΩ and 1R=2 MΩ ACTIVE DIVIDER). Active divider circuits are clearly effective in eliminating
gain fluctuations while still limiting the voltage divider current.
If the active divider circuit is required for your application,
please contact our sales office nearest you.

PRECAUTIONS FOR USE
● Handle tubes with extreme care
Photomultiplier tubes have evacuated glass envelopes. Allowing the glass to be scratched or to be subjected to shock
can cause cracks.
plastic base, so care should be taken in handling this type of
tube. For example, when fabricating the voltage-divider circuit, solder the divider resistors to socket lugs while the tube
is inserted in the socket.
● Keep faceplate and base clean
Do not touch the faceplate and base with bare hands. Dirt
and fingerprints on the faceplate cause loss of transmittance
and dirt on the base may cause ohmic leakage. Should they
become soiled, wipe it clean using alcohol.
● Low temperature storage or operation
Do not leave the tube assembly having a voltage divider in
the environment under -30 °C even in storage. A bare tube
can withstand down to -80 °C.
● Applied force to faceplate
The maximum rating of assembly type is 20 kgf. Do not apply
force to faceplate exceeding 20 kgf.
● Do not expose to strong light
Direct sunlight and other strong illumination may cause damage to the photocathode. They must not be allowed to strike
the photocathode, even when the tube is not operated.
● Handling of tubes with a glass base
A glass base (also called button stem) is less rugged than a
● DO NOT use supersonic cleaner.
● Attached base and socket are only for lab inspection,
and not guarantee for long time operation at high temperature.
