PMT's for THE OPERATION in HIGH MAGNETIC FIELDS over 1 TESLA
In recent years, the demand for photodetectors, that can be

operated in strong magnetic fields has increased, especially in
the field of high energy physics. Conventional PMT's electrons

1.0 tesla. Depending on your needs, you can select from the

PMT's is decreased under such conditions. Therefore, it is
Fine Mesh PMT series.
In addition, socket assemblies and hybrid assemblies can be
necessary for these PMT's to either use a light guide to send
signal light to a region outside the magnetic field or to use a

voltage dividers.

c The voltage indicates a standard applied voltage used to
measure anode characteristics. The voltage distribution

e The maximum ambient temperature range is -80 °C to
+50 °C. When a PMT is operated below -20 °C, please
consult our sales office.
f The maximum anode to cathode voltage is limited by the
internal structure of the PMT. Excessive voltage causes

h Time Response
Rise Time
The time for the anode output pulse to rise from 10 % to 90
% of the peak amplitude.
Electron Transit Time
The time interval between the arrival of a delta function light
pulse at the photocathode and the instant when the anode
output pulse reaches its peak amplitude.
T.T.S. (Transit Time Spread)
This is the fluctuation in transit time among individual
pulses, and is defined as the FWHM of the frequency
distribution of transit time. T.T.S. depends on the number of
incident photons. The values in this catalog are measured
in the single photoelectron state.
TPMHC0098EA
In this drawing, Rp is a protection resistor which prevents
damages to the signal readout unit when the PMT generates a large output pulse, and Rd is a damping resistor
which reduces ringings of output pulses.
i The definition of the pulse linearity is proportionality
between the input light amount and the output current in the
pulse operation mode.
Typical values of pulse linearity are specified at two
deviation points of ±2 % and ±5 % from linear proportionality.
