1.0 INTRODUCTION
The XR150 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 XR150 is an industrial type open beam x-ray generator intended to radiograph inanimate objects. The XR150
is a pulsed x-ray device that produces x-ray pulses of very short duration (30 nanoseconds). The energy produced
by the XR150 is up to 150kVp, which makes it possible to radiograph up to one half (0.5) inch (1.27 cm) of steel.
XR150 standard accessories are two keys, two 12V (or 10.8V) battery packs, and one battery charger. Remote
cable, carrying case are also common accessories.
2.0 WARNINGS
The XR150 is a pulsed X-ray generator that emits hazardous ionizing radiation when pulsing. The XR150 should
only be operated by authorized personnel who are properly trained to safely operate the generator. The XR150
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 XR150. 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 XR150 is used within federal and state guidelines.
All operators and users of the XR150 x-ray machine 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 (note: an electronic dosimeter will not detect the XR150 radiation
pulses). 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 XR150, survey meters of the Geiger-Mueller and scintillator type do not
accurately detect the radiation emitted from the x-ray source.
Survey meters should be of the ionization type and should be used in the integration mode. Survey meters must not
be used in the rate mode because the XR150 does not produce constant radiation. The XR150 produces 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 XR150 has no explosion proof rating and should not be used in an explosive atmosphere. The Spark Gap
is vented to the air and could be a source of ignition.
DUTY CYCLE WARNING
The XR150 is a light duty machine that is not made to pulse continuously. The maximum duty cycle for the XR150
is 100 counts (300 pulses) every four minutes (1500 counts/4500 pulses per hour). Exceeding the duty cycle
will shorten the life of the tube and head. In temperatures above 90 °F (32.22 °C) or continual use, rest 30
seconds after every 50 pulses and 4 minutes after every 200 pulses.

4.0 DESCRIPTION OF OPERATION
The block diagram below illustrates how the XR150 functions. The following sequence of events
takes place each time the XR150 is fi red:
1. User initiates operation of the machine.
2. The control section sends a signal to the converter section to begin oscillating.
3. Once oscillating, the converter section changes the 12 volts DC to 22Khz AC.
4. The transformer charges the High Voltage Capacitor to about 8000 volts.
5. The spark gap arcs after the High Voltage Capacitor reaches proper 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 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 XR150 cannot
produce x-rays without the pulsing sound so it serves as an additional warning the XR150 is
functioning.
This unit generates x-rays through high voltage bombardment of a tungsten target. The XR150 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.

5.0 OPERATING INSTRUCTIONS
The following are basic operation instructions to take an X-ray image using the XR150. Certain applications may
require modi cations to these basic procedures.

8
*XR150 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 XR150
and imager is usually 24 to 72 inches (30 to 180 cm). During operation XR150 should be stabilized on a  at
surface, a tripod, or a custom  xture suitable for holding the 5 pound (2.2 Kg) XR150.
**OPERATING PRECAUTIONS: The operator should always stand at least 10 feet (3m) behind the X-ray
unit and clear all personnel at least 10 feet (3m) behind the unit or at least 100 feet (30m) from the front of the unit
before pulsing. The exclusion zone (below) should be a controlled area free of all personnel while
X-ray pulses.

PULSE COUNT EXCEEDS DUTY CYCLE
XR150 Duty Cycle is 100 counts (300 pulses) every 4 minutes. Exceeding the duty cycle on a continual basis will
shorten the life of various components in the high voltage head. It is recommened to stay within the duty cycle,
however, there may be emergency situations that operators need to exceed the duty cycle. If the duty cycle has
been exceeded Golden Engineering may not honor the warranty (depending on how many times the duty cycle has
been exceeded and the highest pulse count  red at one time).
If the operator enters a pulse count higher than the duty cycle (100 counts/300 pulses) the software will indicate
“Counts > 100 / 4 min” which means pulse count has exceeded the duty cycle. The LCD will prompt the operator
to split the total count into multiple pulse trains. If operator selects “Y” the total counts will be separated to pulse
trains of 25 counts (75 pulses) with a 60-second rest between pulse trains. If operator selects “N” the LCD will
display Settings Void Warranty Continue. Press ENTER to continue with pulse count that exceeds the duty cycle.
Select “N” to go back to “Set CT” screen.

MULTIPLE PULSE TRAINS EXCEED 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. Example below 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
decrease the number of pulse counts from 25 to 10.

17
RESET PULSE COUNTER
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.
LIFETIME PULSE COUNT
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.

PULSE/COUNTS MODE
The PULSE/COUNT feature allows operators to change the setting to PULSE which will  re one pulse per number
displayed on the LCD. The output dose of the XR150 is 1 mR per pulse. The output dose of other Golden X-ray
models (Inspector Model 200, XR200, and XRS-3) is 3 mR per pulse. Due to the differences in output dose the
standard version of the XR150 software historically pulsed 3 times per COUNT entered on the LCD. The output
dose of the XR150 is 3 mR per COUNT (3 pulses) equaling to the same dose as other models. XR150 default
setting is COUNT.
