X-ray generators from Golden Engineering are industrial type open beam X-ray generators intended to
radiograph inanimate objects. The devices are a pulsed X-ray device that produces X-ray pulses of very short
duration (10-50 nanoseconds). The energy produced by the X-ray generator varies from model to model, and in
the XR150 12V is approximately 150 kVp, which makes it possible to radiograph up to one (1/2) inch (1.27 cm)
of steel.
Each unit ships with two keys, two 12V battery packs, and one battery charger.
Many users choose to add other accessories like a Remote Cable or Carrying Case. Refer to the Spare Parts and
Accessories section for more details.
INTRODUCTION
RADIATION WARNING
The X-ray generator produces high levels of radiation and must be operated by qualied personnel
who have read the WARNINGS and OPERATING INSTRUCTIONS sections of the manual before
operating the device.

The X-ray generators from Golden Engineering are pulsed X-ray generators that emit hazardous ionizing
radiation when pulsing. The unit should only be operated by authorized personnel who are properly trained to
safely operate the X-ray generator. The X-ray generator must be registered with proper authorities prior to use
and should not be used to intentionally expose humans.
Develop and closely follow a safe operating system for using the X-ray generator. The safe operating system
must ensure that no one is exposed to radiation above the permissible limits which are 2 mR (0.02 mSv) per hour
for a member of the public. The safe operating system must ensure the X-ray generator is used within federal
and state guidelines.
All operators and users of the X-ray generator must wear a personal radiation monitoring
device, such as a TLD (thermoluminescent dosimeter), lm badge, and/or a pocket dosimeter
consistent with the appropriate federal, territorial or provincial standards. If an operator or
bystander is exposed to an unacceptable level of radiation
contact your Radiation Safety Ofcer and/or appropriate
health care provider.
Due to the short pulse width of the pulsed X-ray, survey meters of the Geiger-
Mueller and scintillator type do not accurately detect the radiation emitted
from pulsed X-ray generators.
Survey meters should be of the ionization chamber (ion chamber) type and should be used in the integration
mode. Survey meters must not be used in the rate mode because the pulsed X-ray generator does not produce
constant radiation. Pulsed X-ray generators produce very high rates of radiation for very short periods of time
resulting in either unrealistically high readings or no readings for a survey meter in rate mode.
The X-ray generators have no explosion proof rating and should not be used in an explosive atmosphere. The
Spark Gap could be a source of ignition.
WARNINGS
NOTE: Electronic dosimeters
and survey meters of the
Geiger-Mueller and scintillator
types may not detect the X-ray
Generator’s radiation pulses.

CONTROLLER
BLOCK DIAGRAM
DESCRIPTION OF OPERATION
1. User initiates operation of the machine.
2. The controller sends a signal to the converter to begin oscillating.
3. Once oscillating, the converter section changes the DC battery voltage to 22Khz AC.
4. The transformer charges the High Voltage Capacitor to about 9000 volts.
5. The spark gap arcs after the High Voltage Capacitor reaches peak voltage.
6. The pulse detector signals the control block that the unit has pulsed.
7. As the High Voltage Switch is closed, a high voltage transient of approximately 150,000 volts
and 10-30 nanoseconds in duration is applied across the X-ray tube generating X-rays.
The closing of the High Voltage Switch produces an audible pulsing sound. The X-ray generator cannot produce
X-rays without the pulsing sound so it serves as an additional warning the unit is functioning.
This unit generates X-rays through high voltage bombardment of a tungsten target.
The X-ray generator does not contain radioactive materials.
All the high voltage is contained within the aluminum canister and as long as the canister is not punctured the
operator is not exposed to dangerous voltages.

** The operator should always stand outside of the exclusion zone. The exclusion zone (below) should be a
controlled area free of all personnel while X-ray pulses.
* The X-ray generator should be positioned directly in front of the object to be X-rayed and the imager placed
directly behind the object to be X-rayed. Imager should be placed as close to the object as possible. Distance
between X-ray generator and imager is usually 24 to 72 inches (60 to 180 cm). During operation the unit should
be stabilized on a at surface, a tripod, or a custom xture suitable for holding the weight of the device. Refer
to the Specications table for details.

DUTY CYCLE WARNING
The XR150 is a light duty machine that is not made to pulse continuously. The maximum duty cycle for the units is
100 counts (300 pulses) every four minutes. In temperatures above 90°F (32.22°C) or continual use situations,
rest a minimum of 30 sec every 50 pulses and 4 min after every 200 pulses. Exceeding the duty cycle will shorten
the life of the tube and head, and may also cause thermal damage to the circuit boards.
Pulse counter is similar to a trip odometer on an automobile. The
counter can be reset to 0 to track the number of pulses since it was
reset. Operator can use this feature to track number of pulses
since the last tube replacement, number of pulses used on a specic
job, or any other event the operator wants to track.

Press ANY key
PULSE COUNT EXCEEDS DUTY CYCLE
If the number of counts exceeds 100 (300 pulses),
the unit will automatically split the pulses into
consecutive pulse trains of 25 counts (75 pulses) with
a delay 60-second delay between them. See the
below example of setting 200 counts.
Set PULSES higher than 200,
press Enter.
Lifetime pulse count tracks the total number of pulses the unit
has red. Please note the number displayed on the LCD is
total number of PULSES the unit red, NOT the total number of
COUNTS. The XR150 res three pulses for each count entered
so the 12,549 Lifetime pulses that appear on LCD below equals
4183 lifetime COUNTS the XR150 has red.
LIFETIME PULSE COUNT
It may be necessary to re the whole
pulse train without splitting it. To
manually override the split, rst disable
the Duty Cycle Warning in the
Home - DutyWarn menu (see pg 17).
The unit is now ready to re the
complete entered pulse train.
After the Duty Cycle Warning is
disabled, the generator will allow pulse
trains larger than 100.
Set the desired number of pulses on the
Set CT screen and press Enter.

menu on page 17.

MULTIPLE PULSE TRAIN EXCEEDS DUTY CYCLE
If multiple pulse train combination exceeds 100 counts in 4 minutes the LCD will
warn that settings exceed duty cycle and ask if operator wants to continue. The
software will allow operator to continue, but they must acknowledge that they
are exceeding duty cycle and could void the warranty.
This example incidates 6 pulse trains of 25 counts with a rest of 10 seconds
between pulse trains.
Unit would have been within the duty cycle had the operator entered at least
60 seconds between pulse trains of 25 counts, decreased to 4 pulse trains of 25
counts, or decreased the number of pulse counts from 25 to 10.

ERROR MESSAGES
Displayed if duty cycle is reached (100 counts in 4 minutes).
Current not detected. No current ow going to the head.
Occurs at beginning of pulse train. Check 20 amp fuse on the
oscillator board. If fuse is ok problem could be in head or
electronics. Replace board or send back for repair.
Pulse rate is slower than 1 pulse per second. Either low
battery, problem with transformer, or electronics. Charge
battery, or replace oscillator board.
Battery voltage is too low to pulse XR150. Charge the
battery.
The failsafe warning LED is not lighting up. The control board
may need to be replaced or the unit may need to be returned

Occurs when the generator is powered off with multiple pulse
trains set. On the Continue screen, select NO to return to a
single pulse train, or YES to keep the multiple train setting.
The boot screen displays an asterisk (*) when the warranty has
