2. SPECIFICATION
2.1 Camera Specification
The Eagle XV is designed for in vacuum direct X-ray imaging. The camera uses a choice of
back-illuminated CCD sensors with a resolution of 2048x2048 or 1024x1024 available, all with
16 bit digital output formats. Low-noise electronics provide a linear response and sensitivity.
Cooling to -80 C is achievable using a TEC and liquid cooling in a vacuum environment. This
level of cooling gives an ultra-low dark current reading of 0.0005e-/p/s in the standard sensor
format, allowing for longer integration times.
The Camera Link digital interface provides the most stable platform for data transfer and the
camera will work with any Camera Link standard frame grabber.
2.2 Specification Table

3.3 Input Power to Power Supply Module
12VDC power is delivered to the power supply module via a 2 way LEMO socket, P/N
EGG.2B.302.CLL. The corresponding plug connector is P/N FGG.2B.302.CLAD92 (for
normal entry version) or P/N FHG.2B.302.CLAD62 (for right angled version). The pin out of
the connector is detailed in the table below.
Pin Number
Connection
1
+12VDC
2
GND
3.4 Power Consumption
Unit input power specification is +12VDC ± 10%, power dissipation ≤8W with the TEC
switched off. Additional inrush current (peak power) is required when the cooler power is
switched from low to high. Peak power ≤85W with total, steady state power consumption
≤65W. The power supply module requires a means of removing the heat dissipated by it,
e.g. by screwing the module to a metal surface.
3.5 Trigger IN
External synchronisation with the start of integration signal may be achieved using the
Trigger IN connector. Input impedance = 510Ω, 200pF input capacitance. Input logic levels
are:
- Logic HIGH > 2.31V
- Logic Low < 0.99V
Min. pulse width = 100ns
3.6 Trigger OUT (Exposure)
For all modes of the camera the Trigger output, Exposure SMA, will represent the integration
period of the sensor. The trigger output signal will be a TTL output pulse. The signal will
remain low (0V) and then be driven high during the integration period. The source
impedance will be equal to 50Ω.
3.7 Trigger OUT (Readout)
For all modes of the camera the Trigger output, Readout SMA, will represent the duration of
the CCD readout. The trigger output signal will be a TTL output pulse. The signal will remain
low (0V) and then be driven high during the readout period of the CCD. The source
impedance will be equal to 50Ω.

5. VACUUM ENVIRONMENT AND PRECAUTIONS
This section outlines information regarding using the camera in a vacuum environment and
highlights important precautions to be aware of.
5.1 CCD Sensor Precautions and Camera Storage
The camera is supplied with a temporary plate attached in front of the sensor for protection
during transit. An O-ring seal prevents dust ingress during shipping and handling.
Take care when removing this temporary plate as the CCD sensor surface will be exposed
and could suffer inadvertent mechanical damage (e.g. from the O-ring) or contamination
from the local environment, see Figure 4. It is recommended to keep the temporary plate
and O-ring for storage of the camera when not in use or for transportation. Regarding
storage temperature, this can be seen from the specification table (-40 C to +70 C).
If the sensor becomes contaminated due to an accident or misuse, please contact Raptor
immediately.
5.2 Chamber Pumping and Venting
Take care when pumping (or venting) the vacuum chamber, ensuring that any gas flow
experienced by the sensor will not cause damage to the bond wires.
Make sure that particulate material does not strike the sensor during the venting process.
Always warm the sensor up to room temperature before venting the vacuum chamber.
Figure 4: Removing Front Plate and Temporary
O-ring.
11
5.3 Vacuum Pressure
It is recommended that the local pressure around the sensor is <5x10-5 mbar (<3.75x10-5
torr) to achieve maximum cooling. Many pressure gauges emit radiation which can be
detected by the CCD sensor, if this background signal is affecting your data acquisition it
may be necessary to switch off the pressure gauge, once you are satisfied that steady state
conditions have been achieved.
Never cool the sensor below the dew point of the environment that it is in, otherwise
permanent damage due to condensation may occur. Switch the cooling off
immediately if you suspect condensation is forming on the sensor.

Hold central nut of Swagelok fitting
secure before attaching (or detaching)
pipes.
5. CAMERA & CHILLER SETUP
This section discusses setting up the camera for operation, including connecting the coolant
pipes, along with a description of all feedthrough parts. The use of liquid cooling is also
discussed, as well as stating important precautions when using the camera.
5.1 Liquid Cooling
This section discusses setting up the liquid cooling, as well as using the Thermotek chiller, if
purchased from Raptor.
Liquid cooling must be used when using the TEC. This is needed to dissipate heat
away from the hot side of the TEC. Do not enable the TEC if liquid cooling is not being
used, otherwise damage to the camera will occur.
5.1.1 Liquid Cooling Connection to the Camera Head
The camera electronics drive a ThermoElectric Cooler (TEC) to cool the CCD. The hotside
of the TEC MUST be cooled via circulating coolant. Connection to the coolant channel is
made via two Swagelok compression fittings, suitable for connection to ¼” O.D. coolant
pipes, as shown in Figure 5.
Please ensure compatibility with these connectors on the camera module before attempting
to connect the coolant supply. Also ensure the coolant connections are completely leak tight
before pumping the vacuum system down and circulating coolant. The TEC within the
camera must not be switched on without coolant circulating through the camera otherwise
permanent damage may occur.
Ensure ferrule set is in place and pipe is
seated correctly in fitting before
tightening.
Figure 5: Connecting the Coolant Pipes.

5.2.2 Connecting the Camera and Chiller
Raptor uses a Chiller from Thermotek, the T257P Precision Chiller. For the datasheet and
full user manual from Thermotek, please contact Raptor and we can provide this. The
manual should be included with the chiller, however. The instructions to set up the chiller are
as follows:
1. Connect the T257P chiller to the Eagle XO using the tubing provided. Connection to the
coolant channel on the camera is made via two quick release valve coupling bodies. The
polarity of the tubing connections does not matter.
2. Keep the chiller horizontal and on a level surface.
3. Make sure there is a minimum 12” clearance and free path for flow of air entry and exit at
the left side and right side of the T257P chiller prior to operation.
4. Remove the reservoir cap and add coolant to the reservoir until the fluid reaches the
bottom of the neck. Please refer to section 6.3 for recommended coolants.
5. Close the cap securely to the reservoir. Make sure not to overfill the reservoir.
6. Install the appropriate end of the power cord into the unit and connect to the mains
electricity.
If using another chiller model, please refer to its manual for start-up instructions.
5.1.3 Recommended Coolants for the Chiller
The recommended coolants are:
Option 1: Distilled Water
Option 2: 95% distilled water and 5% isopropyl alcohol mixture prevents bio growth.
Option 3: 80% distilled water and 20% inhibited Glycol mixture for set temperatures below
5 C.
Raptor recommends using option 3. If purchasing the Thermotek model from Raptor or using
a demo kit provided by Raptor, there will be inhibited Glycol mixture provided to mix with
water.
5.1.4 Setting the Coolant Temperature for Re-circulation
When powering up the chiller, the screen will immediately give the option to set the
temperature of the coolant. It is recommended to set a 20 C set point. After the set point has
been configured, selecting start will initiate the coolant re-circulation. For more detailed
information on all the operating modes of the T257P Precision Chiller, please refer to the
Thermotek user manual.
Never cool the sensor below the dew point of the environment that it is in, otherwise
permanent damage due to condensation may occur. Switch the cooling off
immediately if you suspect condensation is forming on the sensor.
5.2 Connecting the Camera and Frame Grabber
The camera has the normal MDR port on the interface. The main frame grabber that Raptor
offer with this camera has the normal MDR port (EPIX EB1). Therefore, one MDR –MDR
Camera Link cable is required to connect the camera to this frame grabber.
14
6. FEEDTHROUGHS
This section will give information on the feedthroughs used for the camera interface
connections.
6.1 Power Feedthrough
The power feedthrough, shown in Figure 6, connects the power supply module (at
atmospheric pressure) to the camera head (in vacuum). The power feedthrough, shown in
Figure 6, requires a Ø15.1mm through hole with a maximum wall thickness of 21mm. The
female side of the feedthrough must protrude into the vacuum chamber. The power cable
with grey insulation is intended for in-vacuum connection. Always ensure the cable polarity is
correct before attempting to plug in the cable, never force the connection as this may result
in damage to camera system components.
6.2 Camera Link Feedthrough
The camera head is connected to the frame grabber by means of a Camera Link
feedthrough flange, as shown below in Figure 7. The O-ring side of the flange must be the
vacuum side when the flange is installed.
Figure 6: Power Feedthrough.
Figure 7: Power Feedthrough.
15
The recommended cut-out is 65mm x 26mm as shown in Figure 8. The bulkhead flange
must be secured using 4-off screws at the corners, also indicated in Figure 8.
Figure 8: Dimensions and cut-out for Camera Link Feedthrough Flange.
16
6.3 Trigger Feedthrough (Optional Item)
Connection(s) to the SMA trigger input / outputs on the camera head can be made using co-
axial cable and a SMA feedthrough flange, such as that shown in Figure 9. Contact Raptor
Photonics Ltd to discuss flange size and format options.
6.4 Liquid Feedthrough (Optional Item)
Coolant connections to the Swagelok fittings on the camera head can be made using ¼” OD
pipe and a feedthrough flange, such as that shown in Figure 10. Contact Raptor Photonics
Ltd. to discuss flange size and format options. Ensure that no torque is transferred to the
mounting flange to pipe joints when tightening the Swagelok connections.
Figure 9: Trigger Feedthrough.
Figure 10: Liquid Feedthrough.

7. SOFTWARE COMPATIBILITY
This section outlines the options relating to software that are available for the Eagle XV.
7.1 XCAP Compatibility
Raptor works closely with EPIX who integrate all of the Raptor camera models into their
XCAP Imaging Software package. XCAP is the core plug and play software package that is
offered with Raptor cameras.
7.2 Micromanager Compatibility
The Eagle XV can be controlled and imaged using the free open source imaging software
Micro-manager.
7.3 LabView Compatibility
Raptor can supply a LabView .icd file which can be used to control the camera on National
Instruments imaging tools such as NI MAX. The file may also be useful if attempting to
create your own LabView VI.
7.4 Custom Software Interfacing
Raptor works closely with EPIX Inc, who integrates all Raptor cameras into their software
package, XCAP. The EPIX frame grabbers are the models that we offer with our cameras.
We offer their Software Development Kit (XCLIB) for interfacing with custom software. If
using a frame grabber from a different company, then you will have to obtain their SDK.
Raptor can provide an ICD which includes a list of all serial commands to control the
camera. This would be required along with the SDK from the frame grabber device to
integrate the camera.

8. XCAP IMAGING SOFTWARE
This section will discuss downloading and acquiring an image using XCAP, as well as stating
system and frame grabber requirements.
8.1 Computer/Laptop System Requirements
The basic requirement is that the PCIe bus of the system must provide sufficient bandwidth
to handle video rate transfers. The amount of bandwidth required depends on the camera in-
hand. The Eagle XV uses a Base Camera Link interface which can be handled with a x1
PCIe bus and PIXCI EB1, providing about 200MB/sec maximum bandwidth. Contact EPIX
Inc. for further information regarding minimum computer/laptop specification requirements to
run the XCAP Imaging Software.
8.2 Frame Grabber Requirements
If using a computer, it is a minimum requirement to use an PIXCI EB1 frame grabber. If using a
frame grabber from another company, the specification requirements of this frame grabber must
meet those supplied by the PIXCI EB1 model.
If using a laptop, EPIX offers base Camera Link frame grabbers for a laptop system, such as the
ECB1/ECB1-34.
8.3 Downloading and Installing XCAP
The latest version of XCAP can be downloaded from the link below:
http://www.epixinc.com/support/files.php
please select the appropriate version of XCAP for your computer. Ensure that you download
from the section labelled “Pre-release version with support for the latest cameras and
latest PIXCI® imaging boards”.Open the downloaded file when complete and follow the
onscreen instructions in the installation wizard. If a pop-up message appears asking whether
to install the PIXCI driver, ensure that you click yes.
8.4 Opening the Camera Configuration
After opening XCAP, select “PIXCI Open/Close” from the “PIXCI” tab from the top menu bar
in the main window. A PIXCI Open/Close pop-up box will open as shown in Figure 11.
