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
can be up to 370kVp, which makes it possible to radiograph up to one (1) inch (2.54 cm) of steel.
Each unit ships with two keys, two 20V 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.

HANDLE
HIGH VOLTAGE PULSER/TUBEHEAD
The main body of the X-ray Generator
is the tube head. The head contains the
tube cavity, cold cathode type X-ray tube,
spark gap, high voltage capacitor, and
transformer.
The standard collimator
located on the front of the
head limits the X-ray beam to
40 degrees. Special order
collimators up to 85 degrees
are available.
PHYSICAL DESCRIPTION
The handle of the XR200 and XRS3 is attached
to the front and back of the Control Module.
The handle of the XRS4 is integral to the body.

The base of the unit contains an
identication label and a ¼-20
brass insert compatible with
standard camera tripods. The
base also accommodates a quick
release external tripod mount. The
identication label located on the
bottom of the generator lists the
manufacturer’s name and address,
model number, serial number,
weight, volt, amp, and production
date.
BATTERY PACK. The standard
battery pack is a DeWalt®

(DCB203).
The X-ray generator is equipped a 21 mm
picatinny rail located on each side of the
housing.

Pressing both Left and Right arrow
buttons simultaneously initiates
the delay mode, allowing the
operator to use the unit without
the remote cable.

Blinks once per second after time
delay button or remote cable button
is pressed to warn that the X-ray
Generator is going to pulse. The light
stays on continuously while the unit is
pulsing.
This is a failsafe warning light. If the
light does not work the X-ray unit will
not pulse. See settings menu for fail-
safe override in emergency situations.
