Radiation Precautions
The COOL-X is intended to generate x-rays up to 35 keV during normal heating
and cooling phases. However, ambient or room temperature fluctuations will also
result in producing a small amount of x-rays.
WHEN NOT IN USE OR IN STORAGE, ALWAYS KEEP THE
PROTECTIVE METAL COVER ATTACHED TO THE FRONT OF THE
COOL-X.
The COOL-X normally emits x-rays in the forward output direction. However,
radiation in other directions is possible and should be addressed with shielding
and/or monitoring in the final application.
Caution
This device produces X-Rays when energized.
To be operated only by qualified personnel.
Radiation levels external to the x-ray generator housing with the cover on does
not exceed 2.5 mrem/h measured 5 cm from the surface of the housing in
accordance with Requirements 5.2.2.1.1 and 5.2.2.2.2 of the NBS Handbook for
Radiation Safety for X-Ray Diffraction and Fluorescence Analysis Equipment
(for more information, see http://www.fda.gov/cdrh/radhlth/pdf/xdfgehb.pdf).
Beryllium Window Caution
The front of the COOL-X is made of a 10 mils (250 µm) Beryllium window.
DO NOT REMOVE the metal cover from the COOL-X until ready to use. The
Be window is extremely brittle and can shatter easily. Do not have any object
come into contact with the window. Do not touch the window because oil from
the fingers will cause it to oxidize. The window cannot be repaired. If the
window is broken the COOL-X element must be replaced.
Beryllium windows damaged by improper handling will not be covered by
the warranty.
Caution
The COOL-X is only one component of an X-ray instrument. It is the
responsibility of the user, the OEM customer, or experimenter to provide a fail-
safe metal enclosure to prevent escaping radiation while using this product. The
final product (turn-key system) must comply with local government regulations to
protect personnel from exposure to radiation. Amptek Inc. bears no responsibility
for the incorrect use of this product.

COOL-X
Miniature X-Ray Generator with Pyroelectric Crystal
Important –Read the precautions on page 2 of this manual before operating this
equipment.
OPERATING INSTRUCTIONS
1) The COOL-X Pyroelectric X-ray generator is completely enclosed inside the small TO-8
package at the tip of the extender.
TURN OFF POWER TO THE COOL-X WHEN NOT IN USE.
2) The Controller is enclosed inside the metal box. The function of the Controller is to supply
power to the X-ray generator, monitor its temperature and automatically change the heating and
cooling phases of the cycle.
Figure 1
Please see Appendix A if the COOL-X emitter element is to be used away from its
Controller.

3) Power to the Controller is supplied by either a 9 Volt battery or an AC adapter. Both are
provided with the unit. The preferred operation of the COOL-X is with the AC adapter. If
battery operation is required, remove the 4 small screws from the top of the box and insert the
provided 9 Volt battery to the terminals.
4) The COOL-X should be mounted on a firm surface using the 4 mounting tabs of the box.
5) Connect the AC adapter to the back of the box and remove the front metal cover.

6) Press the RED power button to start the heating phase of the cycle.
7) The LED will flash RED for the duration of the heating phase.
8) KEEP ALL PERSONNEL AWAY FROM THE FRONT OF THE COOL-X.
CAUTION: X-RAYS ARE PRESENT
9) When the cooling phase starts, the LED will automatically start flashing GREEN. This
pattern of flashing red/green will continue until the red power button is pressed again. Power to
the unit is toggled ON/OFF every time the power button is pressed. When the power is OFF, the
LED is also OFF.
10) At the start of a cycle and in between the heating/cooling phases a “BEEP” sound will be
heard from a small internal speaker to indicate the transition of phases. If the sound interferes
with the x-ray detector due to microphonic pick-up, the speaker can be disconnected. To
disconnect the speaker, remove the cover by removing the 4 small screws from the top. Locate
the small black jumper marked “Beep”. Move the jumper over one pin to eliminate the sound.

WARRANTY INFORMATION
Lifetime of the COOL-X
When not in use, power to the COOL-X should be turned OFF. The COOL-X is not designed
for continuous operation; therefore, its lifetime will depend on how it is used.
If used intermittently, for about 1-3 hours per day, the estimated lifetime of the COOL-X can be
extended to well over 1000 hours. Continuous use of the COOL-X will shorten its lifetime to
approximately 200 hours.
WARRANTY
AMPTEK, INC. warrants to the original purchaser this instrument to be free from defects in materials and
workmanship for a period of one year from shipment. AMPTEK, INC. will, without charge, repair or replace (at its
option) a defective instrument upon return to the factory. This warranty does not apply in the event of misuse or
abuse of the instrument or unauthorized alterations or repair. AMPTEK, INC. shall not be liable for any
consequential damages, including without limitation, damages resulting from the loss of use due to failure of this
instrument. The factory MUST be notified prior to return shipment. All products returned under the warranty must
be shipped prepaid to the factory with documentation describing the problem and the circumstances under which it
was observed. The instrument will be evaluated, repaired or replaced, and promptly returned if the warranty claims
are substantiated. A nominal fee will be charged for unsubstantiated claims. Please include the model and serial
number in all correspondence with the factory.

APPENDIX A
Operation of the COOL-X away from its Controller
The Amptek COOL-X, x-ray generator is designed to be used as an integrated unit together with
its Controller in normal room temperature applications 20oC ±5oC. Operating the unit outside
these temperature conditions may result in faulty operation or damage to the COOL-X emitter.
In normal operation, the COOL-X cycles through heating and cooling phases. Heat-sinking of
the emitter head (TO-8 package) to provide the proper cooling profile is accomplished by having
good thermal contact with the COOL-X Controller housing. Normal air convection is usually
adequate to dissipate the heat from the housing, but performance can be improved by attaching
the housing to a metal plate with 4 screws.
Operation of the COOL-X emitter (TO-8) away from its Controller must be done very carefully,
taking into account the following considerations:
1) Heat-sinking:
The TO-8 emitter head must be mounted on a heat-sink which is kept at room temperature. The
hole pattern for the TO-8 for attaching it to the heat-sink is provided below. The Control
electronics should also be mounted on a metal plate and kept at approximately the same
temperature as the TO-8. This is important because the temperature sensor in the Control circuit
refers to a matched temperature sensor inside the TO-8 emitter head in order to maintain the
proper temperature differentials and temperature limits throughout the heating and cooling
phases of the cycle.
2) Grounding:
The temperature sensor inside the TO-8 emitter head has a normal output voltage in the range of
0.560 to 0.410 volts corresponding to temperatures of 35 to 125°C. The temperature sensor
shares a common ground with the crystal heater which normally draws about 400 mA of current
during the heating phase. It is important to maintain a low impedance Ground return between
the TO-8 (Pin 11) emitter housing and the Controller circuit board ground (4 corner screws) to
prevent overheating or damage to the emitter. A 60 millivolt difference between the two grounds
will result in a 40°C error in the temperature sensor. This may likely result in damage to the
emitter AND VOID WARRANTY.
