The XR200 is a small, lightweight x-ray generator that operates on its own removable battery pack. The XR200 is
a pulsed X-ray device that produces X-ray pulses of very short duration (50 nanoseconds). It produces a low dose
rate comparable to a 0.5 ma constant potential machine. The energy produced by the XR200 is up to 150KVP,
which makes it possible to radiograph up to one (1/2) inch (1.27 cm) of steel.
XR200 standard accessories are two keys, two battery packs, and one battery charger. Remote cable, carrying
case, are also common accessories.
The XR200 is a pulsed X-ray generator that emits hazardous ionizing radiation when pulsing. The XR200 should
only be by who are properly trained to safely operate the generator. The XR200
must be with proper authorities prior to use and should be used to intentionally expose humans.
Develop and closely follow a safe operating system for using the XR200. 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 XR200 is used within federal and state guidelines.
All operators and users of the XR200 X-ray machine must wear a personal radiation monitoring device, such as
a TLD (thermoluminescent dosimeter), lm badge, and/or a pocket dosimeter
(note: an electronic dosimeter will not detect the XR200 radiation
pulses).
Due to the short pulse width of the XR200, 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 modeSurvey meters must not
be used in the rate mode because the XR200 does not produce constant radiation. The XR200 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.
Upside down storage or use may cause
premature failure including no output dose.
The XR200 is a light duty machine that is not made to pulse continuously. The maximum
duty cycle for the XR200 is 200 pulses every four minutes (3000 pulses per hour). Exceeding the duty cycle will
shorten the life of the tube and head.

Figure 1: XR200 X-ray Unit
The main body of the XR200 is the tube head
which 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.
. The base of the XR200 contains an identication label and a ¼-20 brass
insert compatible with standard camera tripods. The base also accommodates a
quick release external tripod mount. The identication 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.
. The standard battery pack
is a DeWalt® 20V 2 amp hour Li Ion battery
(DCB203).
The standard battery
charger is the DeWalt® DCB107 110V charger
or DCB105 220V charger. (Note DeWalt part
numbers may change). Battery charge time is
less than one hour. See battery charger manual
for additional instruction and warnings.
The XR200 has a 21 mm picatinny rail located on each side of
the housing.

The block diagram below illustrates how the XR200 functions. The following sequence of events takes place
each time the XR200 is 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 20 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
50 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.
This unit generates X-rays through high voltage bombardment of a tungsten target. The XR200 does not contain
radioactive materialsAll 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.

Figure 4: Exclusion Zone
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.
*XR200should 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 XR200
and imager is usually 24 to 72 inches (30 to 180 cm). During operation XR200 should be stabilized on a at
surface, a tripod, or a custom xture suitable for holding the 11 pound (5 Kg) XR200.

The following is true when using lm or digital systems that generate a positive image. If the radiograph is too
dark, the lm is underexposed. If the radiograph is too light the lm is overexposed. can be
corrected by increasing the number of pulses and/or decreasing the distance between the imaging medium and
the XR200. can be corrected by reducing the number of pulses and/or increasing the distance
between the imaging medium and XR200.

Low Battery Battery voltage is too low to pulse the XR200. Charge the battery.
Slow Pulsing
More than one second between pulses in a pulse train. Either low
battery, problem with transformer, or electronics. Charge battery or
replace oscillator board.
No Feedback
Current not detected. No current ow going to the head. Occurs at
the beginning of pulse train. Check 20 amp fuse on the oscillator

Using a dosimeter, the average X-ray dose for new tube can be established.
With the dosimeter located 1 foot from the front of the case and in line with the center of the beam angle
label, the reading for 10 pulses should be 26 mR to 36 mR.
The leakage sheet illustrates the X-ray dose and maximum allowable radiation leakage levels for each
X-ray unit. A completed copy of this form accompanies each X-ray.
The XR200 tube should last at least 100,000 pulses. Under normal conditions the tube’s
output will decrease slowly with use. If the tube is broken or glass cracks the tube output will cease immediately.
The following are tube replacement instructions.
1. Remove the battery before unscrewing the collimator.
2. To replace the tube unscrew the collimator.
3. Using needle nose pliers or your ngers grab the front of the tube and pull straight out.
