Flash X-ray Imaging.
Two systems working as one.
Producing flash X-ray radiographs to study HOT SPOTS or DYNAMIC EVENTS requires two systems working together in harmony. The first system, referred to as the Flash X-ray System, is used to create X-ray pulses with either single or multi-anode X-ray tubes. And the second system, referred to as the FXR Image Detection System, is used to capture and convert the X-ray pulses into radiographic images with either an image plate or a scintillator coupled with a high-speed camera.
High-speed imaging up to one million frames per second

4 Essential setups for FXR imaging
From one fixed area of study at one moment in time, to 3D stereo imaging, to high-speed bursts of image sequences, to multi-area time sequence imaging along a trajectory, Scandiflash Flash X-ray tubes are designed to work individually, as well as in numerous combinations to reveal the most intricate and hidden details of the “hot spots” within your dynamic events. Combine any of these four setups and you’ll be able you to study any scenario you can imagine!
1- Single Flash X-ray
Single FXR Imaging is our basic building block and is used to study one “hot spot” from a single angle of view. Either a straight or a right-angled Flash X-ray tube is paired with a Single Imaging Detector to capture one image of a dynamic event occurring at one fixed area of interest.
2- Stereo Flash X-ray
Combine two or more Single FXR setups to achieve Stereo FXR Imaging and you’re able to study a “hot spot” from multiple angles of view. This 3D view is made simple with the Scandiflash Dual Tube option. That’s right, one pulser can power two FXR tubes where each X-ray tube is paired with a Single Imaging Detector and will simultaneously create one image per X-ray tube of the same dynamic event at a fixed area of interest.
3- Cine Flash X-ray
Visualize film-like motion within your dynamic events using Cine or Cinematic FXR Imaging to study a “hot spot” with multiple images from a near-single angle of view. The benefit of Cine FXR Imaging is that it enables “fixed-area time sequence imaging” which produces a high-speed time sequence of images of one event at a fixed area of interest in order to study the progress of the event as it unfolds. Cine FXR Imaging is achieved with a specialized flash X-ray tube known as a Multi-Anode Tube (MAT) paired with a Cinematic Imaging Detector (CID). Take your study a step further and get Stereo Cine FXR with an additional angle of view. Connect two MATs with the Dual Option and capture image bursts with two CIDs!
4- Trajectory Flash X-ray
Unravel the mysteries in your most complex scenarios with a Trajectory Flash X-ray setup. By combining any number of Single, Stereo or Cine FXR setups, you can study multiple stages of dynamic events as they occur along a trajectory or path. Trajectory FXR Imaging enables “multi-area time sequence imaging” which produces a time sequence of images of multiple stages of a dynamic event from a series of fixed areas of interest in order to study the progress of the event as it unfolds along the trajectory.
Flash X-ray Systems
Scandiflash Flash X-Ray Systems generate extremely short pulses used to capture dynamics in the harshest of conditions, ranging from indoor lab setups to outdoor large-scale firing ranges. The systems are modular and can be tailored to meet your requirements for number of pulses and peak energy conditions.
Scandiflash Standard FXR Systems
Scandiflash Flash X-ray (FXR) Systems are valuable solutions to see through plastics, fire, smoke, metal and other materials during dynamic testing in materials science, engineering and more, using short, intense X-ray pulses for high-speed and ultra high-speed imaging. Exposure times ranging from 20–35 nanoseconds make it possible to see events at speeds up to several km/s, and the 1mm focal spot size produces extremely sharp radiographs for analysis. Scandiflash FXR systems feature a wide voltage range and the option of using soft X-rays for optimal penetration and contrast for most applications.
The main components of a Scandiflash Flash X-Ray system are:
- 1 to 16 X-Ray tubes, generating up to 8 consecutive X-Ray pulses from up to two different directions at the same time (dual mode)
- 1 to 4 pulsers that generate a current pulse with an extremely high voltage
- 1 to 2 control cabinets including
- 1 PDU4 power distribution units per cabinet
- 1 to 4 FXRC4 Flash X-Ray channel controllers per cabinet
- 1 SU8 communication switch unit per cabinet
- 1 control computer, controlling the system, including the ScandiControl software
- 1 vacuum pump down and service unit (RPS30)
- 1 Dry air compressor unit supplying the pulser and X-ray tube with isolation gas (CAD70/CAD701)
The different Flash X-Ray system models are denoted according to their peak voltage output, which also determines the performance parameters of the system.
The systems are usually delivered with a set of accessories:
- A number of your choice of digital image plates to capture the high speed event as an X-ray image (alternatively, scintillator screens and high speed cameras can be used)
- Digital image scanner and image software
For accessories like X-ray protection units, stands and frames, see the accessories section.

FXR Image Detection Systems
Based on the two methods that are most commonly used to capture and convert X-ray pulses into radiographic images, Scandiflash offers two types of Image Detection Systems which give the necessary flexibility for various setups and scenarios.
Single Imaging Detector
Our Single Imaging Detector utilizes a combination of an image plate and a scanner which is best paired with a single-anode X-ray tube to capture a single image per event per image plate. The X-rays expose the image plate, creating an imprint of the X-ray intensity. This image is then scanned using a specialized scanner, which converts the stored energy into a visible image. The Single Imaging Detector is ideal for studying fixed areas of interest or visualizing the trajectory of moving objects. Scandiflash provides a range of image plates & cassettes, scanners, and software for optimal image viewing.
Cinematic Imaging Detector
Our Cinematic Imaging Detector employs a scintillator coupled with a high-speed camera. This time-sequence imaging method facilitates the capture of a high-speed sequence of images at different event times by briefly illuminating a phosphor screen while simultaneously recording with a high-speed or ultra high-speed camera. The Cinematic Imaging Detector is ideal for Cineradiographic FXR Imaging.
The Scandiflash Cinematic Imaging Detector (CID) is precisely engineered to seamlessly integrate with the Scandiflash Multi-Anode Tube (MAT) X-ray source which emits a rapid sequence of flash X-ray pulses from a confined area. This configuration is well-suited for studying the impact behavior of materials and structures at high velocities or observing the motion of mechatronic devices within a construction setting.
And to orchestrate the perfect symphony of camera framing and X-ray flashes, the Scandiflash CID seamlessly integrates a delay stage. It grants you complete control over trigger signals, enabling precise synchronization to capture every breathtaking detail of your dynamic events.
The time consuming, detailed and complicated process of custom fabricating your own cinematic imaging detector is no longer necessary as the Scandiflash CID comprises all the distinct elements you’ll need—a fluorescent screen, an optical alignment stage, and a high-speed camera—all working together in perfect harmony to enhance the system’s overall functionality and performance. And best of all, our CID is designed for immediate deployment. It provides a comprehensive, ready-to-use detector, delivering prompt and high-quality imaging solutions. There’s no waiting – you can start collecting data right away!

Pulsers
Scandiflash FXR Systems use pulsers (high-voltage pulse generators) to generate high-intensity X-ray bursts (pulses) for radiography. Scandiflash pulsers are modified Marx surge generators – voltage multiplication is accomplished by charging capacitors in parallel and discharging them in series with spark gaps.
Grounded metal tanks are used to house pulser components – capacitors, spark gap switches and charging network. Pulser tanks are precision-built and pressurized to improve insulation and control over spark gap switch breakdown voltage. The exceptional shielding properties of Scandiflash’s tanks, combined with the coaxial nature of capacitor discharge, lead to unusually low external radiofrequency (RF) electromagnetic radiation levels.

Dual Tube Option
Some of our pulsers are compatible with our Dual Tube Option (see Systems comparison for compatibility). Pulsers equipped with Dual Tube Option allow two X-Ray tubes to be connected to one pulser. The advantage of such a setup is that it is possible to record two X-Ray images of the experiment at the exact same time but from different angles. Note that dual mode also can be retrofitted to your current system.

Anodes & Cathodes
Effortless anode and cathode swapping for streamlined maintenance and cost-efficiency
Imagine the task of producing an abundance of X-rays in an astonishingly brief span, all to capture impeccably clear images of swiftly moving objects without motion blur. While a conventional X-ray apparatus comfortably operates in the keV/mA range, dishing out a few hundred watts of power, our Flash X-ray systems thrive in the keV/kA realm, achieving the remarkable feat of freezing frames within just 20 nanoseconds. This level of power enables the capture of images of objects hurtling at speeds of kilometers per second.
However, this intensified power usage exacts a toll on the anode, leading to accelerated wear and necessitating more frequent replacements compared to their continuous source counterparts. Here’s where the Scandiflash flash X-ray tubes really shine, designed to facilitate effortless maintenance and straightforward anode/cathode replacements. The process entails opening the tube, removing the old anode, and seamlessly installing a new one.

X-ray Shielding
Scandiflash systems have been designed to span a wide range of output voltages and provide flexible tools for the engineer or scientist. Scandiflash XTS series shieldings are designed to fit Scandiflash flash X-ray tubes to reduce the radiation from these tubes in the non-forward direction. The XTS series of products is retrofittable and can be mounted in the field.
FXR Counter
Keep track of your X-ray source history
A hardware and software combination
The Scandiflash FXR Counter is a separate hardware module designed to count the number of CVR signals and report counts in software that can be installed onto the control computer of your setup. This tool is essential for monitoring the usage of your X-ray source and preventing equipment damage.
Retrofittable to Scandiflash Systems
One of the key advantages of the Scandiflash FXR Counter is its retrofit capability. This means that it can be easily integrated into existing Scandiflash systems. If you’re concerned that your cables are not designed to fit CVR’s on the tube and/or pulser side, it’s just a quick fix away. This feature allows for a seamless upgrade, ensuring that you can continue to use your current equipment while benefiting from the enhanced functionality of the FXR Counter. This makes it a versatile and cost-effective solution for managing your X-ray source history.
Why is it Important?
The 20 ns short X-ray pulse generated in Flash X-ray radiography wears down the anode and cathode of the X-ray source. This limits their use from tens to hundreds of flashes, depending on anode size and pulser model. Overuse of an anode can lead to equipment damage, such as a short in the cable. It is crucial to keep track of the number of flashes.
How Does it Work?
The FXR Counter tracks the number of flashes from multiple X-ray sources that are switched between pulsers and even counts the number of discharges from pulsers. This allows you to monitor the total number of delivered high voltage pulses for service intervals. The FXR Counter can handle 12 individual signals, and each counter can be named individually. By using the Scandiflash FXR Counter, you can ensure the longevity of your X-ray source and maintain the efficiency of your radiography operations.
