Systems

Scandiflash Standard FXR Systems

Scandiflash Flash X-ray (FXR) Systems are valuable solutions to see through fire, smoke, metal and other materials during ballistics, hypervelocity impact testing, detonics (ordnance velocity & explosives research), and more, using short, intense X-ray pulses for high-speed and ultra high-speed imaging. Exposure times ranging from 20–35 nanoseconds and 1mm focal spot sizes produce 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.

A. Pulser
B. X-ray tube
C. 19″ Rack mounted control tower

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.

A complete Flash X-ray system is packaged in a 20’ ISO container ready for transport and setup at remote testing sites.

The Mobile FXR Lab is a research center housed in a reinforced, insulated and heated container. Scandiflash Mobile FXR Labs are built on-demand and outfitted with the exact Flash X-ray system required for your research.

Once onsite, setup is fast with multiple access ports for Flash X-ray tubes. Everything your system needs is included in the Mobile FXR Lab.

Container Dimensions (LWH): 20 x 8 x 8.5 ft (6.06 x 2.43 x 2.59 m)

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.

Scandiflash FXR Systems feature cold cathode X-ray tubes with a robust design and small focal spot size – creating the ideal X-ray tubes for recording radiographs of ballistics and hypervelocity impact testing. X-ray tubes XT 150 through XT 450S are self-contained (a separate tube head is not needed for remote operation) and connected to pulsers with a flexible high-voltage coaxial cable. Pulser model PG 1200 features an X-ray tube connected directly to the pulser output.

Each X-ray tube has been designed to be user serviceable – consumable parts can be replaced on site at a fraction of the cost of a new tube to keep your research going strong and within budget.

The same tube can be used for both single and dual tube operation. For applications where low energy radiation is essential for improving contrast, an optional soft X-ray adapter (a thin plastic screen fitted to the tube) may be used for transmitting radiation as low as a few keV.

    • Spot size 1, 2.5 and 4 mm diameter
    • Tungsten anodes (standard, can be replaced with other materials)
    • Broad band X-ray spectra from 20 keV to pulser kVp
    • Soft X-ray option window available (6 keV)
    • Lightweight and easy to handle
    • Easy to service and maintain

Focal Spot Size & Radiographs

Focal spot size plays an important role in the quality of radiographs – smaller focal spot sizes, produce sharper radiographs.

Flash X-ray tubes may be used with a 1mm focal spot size resulting in sharp radiographs, even at short source to object distances.

Multi-Anode Flash X-ray Tubes

Capture 4-8 images simultaneously

C. Projectile
D. Gun 
E. Scintillating Screen
F. Intensifier
G. High-Speed/Ultra High-Speed Camera

Multi-anode Flash X-ray tubes are used when closely spaced X-ray sources are needed to minimize parallax. Radiation from the tube is directed onto a scintillating (fluorescent) screen placed behind the subject. The scintillating screen converts the radiation into visible light and produces images on the rear side which can be intensified and captured with a high-speed or ultra high-speed camera.

The SU 8 is an 8-channel Ethernet switch that handles communication between computer and FXRC 4 units. It features a built-in Ethernet to fiber optic modem for using fiber optic cable for long distance operation.

ScandiControl* by Scandiflash

ScandiControl is software developed for the operation and control of Scandiflash FXR systems. ScandiControl gives you full remote control of all settings and operational parameters while handling up to eight channels of your FXR system.

ScandiControl has four user modes:

ScandiControl config: used to configure system hardware at the factory before shipping. This mode allows the user to extend the FXR system by adding or removing components.

ScandiControl User: standard mode for taking radiographs

Test Mode User: for system operation with resistive loads

Scandiflash: allows Scandiflash personnel to log into your computer and run ScandiControl for diagnostic purposes 

* ScandiControl is the property of Scandiflash and does not require a third party license.

Eco-friendly compressed dry air is used in Scandiflash FXR Systems instead of SF6 (Sulphur hexaflouride, a toxic potent greenhouse gas) to improve insulation of high-voltage pulsers & X-ray tube cables, protection from environmental conditions and to control the breakdown voltage of fixed spark gap switches inside the pulsers.

Scandiflash CAD 70 compressed air drying system has been meticulously designed and includes a compressor, cooler, adsorption dryer & storage tank to produce high-quality compressed dry air on-demand for optimal research results with your FXR system.

NOTE: Compressed dry air obtained from local gas suppliers must be dust & moisture free for reliable and stable FXR system operation.

Service Station

Roughing Pump System (RPS)

Scandiflash X-ray tubes are easy to maintain and can be efficiently serviced on site to get the most of your research. An integrated ion pump is supplied with every X-ray tube – the RPS uses a turbo molecular pump to evacuate X-ray tubes and reset the ion pump pressure for your next exposure. Two RPS models are available – RPS 30M for pumping a single X-ray tube and RPS 30M-4 for simultaneously pumping up to four X-ray tubes.
