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.
How to Use this Manual
This manual provides an in depth discussion of JSR-15R Neutron Analysis Shift
Register operations.
Chapters
Chapter 1, Introduction, introduces you to the JSR-15R.
Chapter 2, Controls and Connectors provides a brief overview of the JSR-15R
controls and connectors.
Chapter 3, Operation, covers the basic operation the JSR-15R including the three
main menus.
Chapter 4, Maintenance,provides information on how to care for your unit plus a
troubleshooting guide.
Appendices
The appendices offer additional information to supplement routine operation.

2. Controls and Connectors
This chapter covers the JSR-15R display, controls, and connectors.
Front Panel Controls
Figure 1 shows the JSR-15R’s front panel, and is followed by a description of its
controls.

LCD Display
A backlit LCD display is used for all system settings, battery status, and data displays
as well as for the setup screen used to change individual parameters.

Up/Down Arrow Keys
The up/down arrow keys provide a means to navigate through the parameters in each
menu.
Left/Right Arrow Keys
Reserved for future use.
Numeric Keypad
Directly below the Arrow Keys is an 11-key numeric keypad that is used for entering
parameters into the JSR-15R.
Function Keypad
To the right side of the front panel is the Function Keypad. The five keys are
described below.
Setup
The Setup key allows you to enter into the main system menu. The Setup menu
provides access to parameter settings and display. See Chapter 3, Basic Operation,
for more information.
(The RUN display is accessed by the RUN/STOP button, not through the SETUP
MENU display. The 'Battery Display' option in the SETUP MENU is just a display,
not a menu since you cannot actually choose anything in that display.)
Run/Stop
The Run/Stop key is used to start or end the count.
Run will begin the measurement, showing the instrument settings and the results
of the current measurement.
Stop will halt any measurement in progress, and display values currently in the
counters. If the system is not reset after stop is pushed, it can be restarted without
a loss of data.
Enter
The Enter key is used in the SETUP menu to activate selected items.
Cancel
Reserved for future use.

On/Off
Press on the ON/OFF key for a few seconds to turn the unit on or off.
Rear Panel
Located at the Rear Panel (from left to right) of the JSR-15R are its connectors, each
of which is described in this section (see Figure 2).
Figure 2Rear Panel Connectors
HV
This SHV output supplies high voltage (0 to 2000 V dc ±2 V typical;
±5V guaranteed) to the neutron detectors. It has a maximum current capacity of
0.7mA. For high voltage settings below 500 volts, the tolerance is not assured.
5V
This BNC output connector outputs +5 V dc ±100 mV at 0.5 A power for the external
amplifier used with neutron detectors. It is short circuit protected.
AUX2
BNC connector accepting a TTL compatible input for a second auxiliary totals scaler.
