Preface
The JSR-15R, shown below, is a
desktop shift register/multiplicity
instrument used to record time-
correlated electronic pulses. The
unit is supplied with rack mount
brackets to mount in standard 19”
rack either single unit or two side by
side. The input to the instrument
can be either TTL pulses via a
coaxial cable or differential pulses
via a twisted pair cable. These
pulses are counted inside the JSR-15R and the time correlation of these pulses is
displayed and/or communicated via a Ethernet connection. The instrument counts the
total number of pulses, the coincidence timing of the pulses and the multiplicity
distributions of the coincident events.
The JSR-15R has two interface mechanisms: a front panel pushbutton/LCD display
and software including the CANBERRA NDA 2000 and the International Atomic
Energy Association (IAEA) accepted LANL software, INCC. The software interface
is through an Ethernet interface. The JSR-15R is fully compatible with the existing
CANBERRA NDA 2000 and INCC software.
The JSR-15R has a built-in battery pack which is helpful to continue measurements
during short duration of power loss (less than 1 hour). The instrument is not meant to
run on battery power alone as the portable Handheld JSR-15. The JSR-15R is meant
to be powered via its external 5VDC power supply. The battery pack consists of
three rechargeable lithium ion batteries. The instrument has both a built-in charging
circuit and a battery monitor circuit. The state of the battery is reported on the front
panel LCD display.
The JSR-15R contains a user-programmable High Voltage (HV) power supply and a
5V supply that can provide bias and power to the user’s detector assembly.

How to Use this Manual
JSR-15R User’s Manual – 7093118B 1
1. Introduction
This manual provides the operator with the product description and the complete
instructions on the manual setup and control of the unit, and it also provides the
programmer with complete protocol information on computer-controlled operation.
The JSR-15R Neutron Analysis Shift Register is a fully computer-controlled, neutron
analyzer that functions in the Canberra 2150 Multiplicity Mode. The JSR-15R is a
specialized pulse counter used primarily to count neutron events originating in
neutron detection instruments. While the counter can be used to count any TTL or
differential input pulses, its ability to record time correlated events and the
multiplicity distributions of these events makes it an ideal instrument for counting
neutron events in the nuclear fields of material safeguards, waste assay and process
monitoring and control.
The JSR-15R complies with the International Atomic Energy Association (IAEA)
neutron coincidence counting requirements.
