ORTEC® ICS™
INTE RATED CRYOCOOLIN SYSTEM
1. INTRODUCTION
The ICS™ is a highly reliable, maintenance-free, electromechanically cooled cryostat deli ering superior performance
for ORTEC high-purity germanium (HPGe) detectors. The industry-pro en AMETEK Sunpower® CryoTel® cryocooler has
a ser ice life of >200,000 hours for unmatched operational reliability.
ICS incorporates ANC™ (Acti e Noise Cancellation) technology, and is designed to irtually eliminate ibrational and
audible noise le els. This pro ides resolution performance comparable to liquid nitrogen cooled systems in all
operational orientations, making it the choice for users seeking premium resolution and ersatility in a broad array of
HPGe applications.
The acuum-hardened cryostat eliminates the need to thermally cycle the detector in the e ent of a partial warm-up.
2. INSPECTION FOR SHIPPING DAMAGE
If a shipping carton(s) arri es with externally isible damage, do not unpack it. Notify the carrier and make arrange-
ments to file a damage claim. In all cases of shipping damage, it is the customer's responsibility to file a damage
claim.
If, during unpacking, you find concealed damage, notify the carrier and file a claim. Preser e packing materials,
waybills ,and other such documentation to establish claims.
Contact the ORTEC Global Ser ice Center, 1-800-251-9750 or [phone], for further instructions. Outside the
USA, contact your local ORTEC representati e.
3. OPERATING CAUTIONS AND NOTES
3.1. HANDLIN AND MOVIN THE ICS
When lifting or mo ing the ICS:
●Do not place any load on the detector housing or cryostat (i.e., do not use the detector/cryostat assembly as
a contact point with any other surface). Compressing, denting, or bending any part of this assembly may
damage the detector element or breach the cryostat acuum, and will void your warranty.
●Do not attempt to lift the ICS by the detector housing or cryostat. This may damage the detector element or
breach the cryostat acuum, and will void your warranty.
WARNIN
Because of its weight, the ICS is rated by OSHA as a two-person lift. In addition, it is significantly nose-heavy. Keep
this in mind when lifting and positioning the unit.

3.2. ELECTRICAL CAUTIONS
If the mains power cord is damaged, contact ORTEC for ser icing information. Do not replace the cord.
3.3. BERYLLIUM WINDOWS AND INTERNAL CRYOSTAT PRESSURE
Some ORTEC detectors ha e beryllium windows, which are especially fragile and can sometimes be ruptured by a light
touch. Rupture of a beryllium indo causes severe system damage, and in some circumstances can cause personal
injury and other health effects. Therefore, do not touch or allow objects to contact a beryllium window. ORTEC ships a
remo able plastic endcap co er with our beryllium-window detectors. Keep this co er on the endcap when the
detector is not in use or if the window is damaged.
If a beryllium window should rupture under normal circumstances, it will implode and personnel will typically not be
exposed to flying fragments and possible injury. Co er the detector window with its the protecti e plastic co er and
tape the co er down so that none of the beryllium pieces can fall out.
A more dangerous situation may result if the beryllium indo ruptures out ard due to a pressure build-up in the
cryostat. This can happen if the cryostat de elops a leak while cold and then warms up. If a cold cryostat shows
e idence of poor acuum, place the protecti e plastic co er o er the beryllium window and secure it with the plastic
set screw(s) or with tape. Symptoms of a poor acuum include an unusually cold cryostat or endcap; moisture
condensation or "sweating"; or, in extreme cases, an outward bulge in the window on warmup.
If the window has a hole or crack, co er the defect with tape, then affix the protecti e plastic co er.
In all cases, disconnect the system from the MCB or other external electronics. Then, before turning off the ICS power
and warming up the cryostat or taking any additional action, contact our Global Ser ice Center or your ORTEC
representati e.
3.4. DETECTOR WARMUP FOR REPOSITIONIN OR SHIPPIN
Once the ICS is cooled, you can power off the ICS for a brief period (e.g., 10–20 minutes) without significantly warming
the detector. When the cryocooler is restarted, the unit typically returns to ready status within a few minutes. The
cryocooler can be restarted at any time without harming the detector element, regardless of whether the detector is
warm, partially cooled, or cooled to operating temperature.
Allow the ICS to warm for 24 hours before enclosing it in packing materials.
DAN ER
Inhaling beryllium dust can lead to a chronic lung disorder called berylliosis. Beryllium has also been listed as a
carcinogen, based principally on animal tests. If a beryllium window should implode, contact our ORTEC Global
Ser ice Center or your ORTEC representati e for shipping instructions to return the detector for repair. In the
e ent that some beryllium pieces fall out of the detector, take care to a oid breathing any dust or powder that
may form. Wearing protecti e glo es and/or using tweezers, pick up pieces in a manner so as not to generate any
dust. Dispose of the pieces according to local or national regulation.
CAUTION Do not enclose the ICS in packing materials or a shipping case hile it is cold. This could allow
condensation to form on the cryostat and enter the enclosure and connectors, potentially damaging
the electronics.

4.2.1.3. INDICATORS
●OVER RAN E Red LED illuminates when a ery high count rate causes preamp o errange.
●SYSTEM COLD Green LED illuminates when the detector is at operating temperature.
●CRYOCOOLER ON Green LED illuminates when the cryocooler is operating.
●POWER Green LED illuminates when system power is applied to the ICS.
4.3. COOLIN THE DETECTOR
To begin the cooling cycle:
1) Place the ICS assembly in its intended operating location and orientation.
2) Make sure the power switch is in the OFF position (position ‘O’) before connecting the power module to the
ICS power connector, then connect the power cord to the power module.
3) Connect the power cord to the mains, then turn the power switch ON (position ‘I’).
4) The POWER LED will illuminate, followed by the CRYOCOOLER ON LED approximately 1 minute later.
The cooling time will depend on the detector size and type, and is listed on the QADS for your detector.
Before attempting to apply high oltage to the detector, it is extremely important to fully cool it according to
the recommended time on the QADS and connect the SHUTDOWN (bias shutdown) cable between the ICS
and MCB or NIM electronics. This will pre ent the premature application of bias to the detector and any
resulting damage that may oid your warranty.
5) When the ICS has cooled for the specified period and the SYSTEM COLD LED illuminates, the detector is fully
cooled and ready for use.
4.3.1. Changing the Orientation of the ICS During Operation
Before changing the orientation of the ICS, switch power OFF then restore power when the unit is in it new position.
4.4. DETECTOR TESTIN
See the accompanying Photon Detector Manual, which contains testing information specific to the detector mounted
on your ICS.
4.5. DETECTOR PERFORMANCE MEASUREMENTS
See the accompanying Photon Detector Manual, which contains performance information specific to the detector
mounted on your ICS.
NOTE If the POWER LED illuminates but the CRYOCOOLER ON LED does not, contact our Global Ser ice
Center for assistance.

5. INSTALLATION NOTES
The ICS can be mounted on a stand (with or without a lead shield) or on the ISO-CART II, or can be placed on a
benchtop.
3
The two ented panels must ha e at least 13 mm (0.5 in.) of entilation space. You may remo e the rubber
feet, if you wish.
5.1. MOUNTIN IN A SHIELD
Installing the ICS under a shield is easiest with two people and a step-stool. The stand and mounting hardware are
a ailable separately from ORTEC, and the stand’s instructions will describe how to mount the ICS and raise it to the
desired height. Regardless of stand or shield type, we strongly recommend the following best practices:
1) The shield and ICS must be positioned so the ICS is easily disconnected from the mains electrical supply.
2) When mo ing the ICS from place to place or raising the detector into the shield, guide the detector cables to
protect the connectors and ensure the wires are not kinked or pulled.
3) To a oid ground loops when using a split center plug, make sure the detector base plate does not touch the top of
the plug.
4) When using a split-center shield plug, do not place the plug on the ICS unit. A dedicated stand for the ICS is
a ailable from ORTEC that pro ides support for the plug.
