FXR Conversations Episode:
Unveiling the Dynamics of 5.56mm Ammunition

In our this episode, we delve into the research conducted by Bartosz Fikus at the Military University of Technology in Warsaw, Poland, where Flash X-ray cinematography was employed to study the behavior of 5.56mm ammunition penetrating a multi-layer matrix of steel plates and porous materials.

Key Highlights:

Cinematic Flash X-ray Imaging: Utilizing the SCF450 4-channel MAT Cine FXR system, researchers captured high-speed time-sequence images at 16-microsecond intervals, providing unprecedented insights into the bullet's interaction with various materials.

Fixed-Area Time Sequence Imaging: This technique allowed for the observation of dynamic events in a fixed area, enabling detailed analysis of the bullet's pe*******on process.

Educational Impact: The study not only advanced ballistic research but also served as a valuable teaching tool, allowing students to visualize complex phenomena in real-time.

This episode is a must-listen for professionals and enthusiasts in the defense, research, and educational sectors.

How are hashtag used for crash and ?

To illustrate the technique of Flash technology, we captured the crash of an egg hitting the floor. This (multi-anode tube) flash X-ray sequence of images show the egg collides with the surface of the floor, the shell breaks, and flash make it possible to monitor the interior of the egg. You can now see how the air bubble moves from the side to the top during the dynamic event. The series of images reveals the possibility to capture information from a moving object that just isn’t possible to deduce from a post-mortem examination of the object under study.
Even if the egg measurement a simple experiment, it demonstrates the possibility of monitoring the effects of helmets or air bags during collisions or how the interior of a mobile phone is affected when it’s dropped. Even if you where a helmet you can get brain damage, now why is that? A study of 6,000 cases reveals that, even if 70% of injured patients were wearing bullet-proof helmets and other individual protective equipment, 50% was found to have suffered brain injuries. (Rafaels, Journal of Forensic Sciences, 60(1)(2015)219).

Norbert Faderl and Marvin Becker at the French-German Research Institute of Saint Louis have constructed an instrument described in Proc. of SPIE 10999(2019)10990L-1, containing a hashtag system that can be used to study why.

is a technique used to capture events that are too fast for conventional methods. It involves generating extremely short bursts of , typically lasting between 20 to 50 . This allows for the visualization of processes, such as , , and other rapid phenomena, even through materials like smoke, fire, and metal.

The technology is particularly useful in fields like , , and , where understanding the behavior of under extreme conditions is crucial. For example, flash systems that can capture images at frame rates up to 1,000,000 frames per second, providing detailed insights into events occurring at speeds exceeding 10 km/s.

A flash of X-rays is produced by charging a Marx generator to hundreds of thousands of volts and then release this voltage all at once in a burst 20-50 nanoseconds long into an X-ray tube that generates the X-rays.

The type images are captured by detectors that convert the X-rays into visible images. The more X-rays that hit the detector the brighter it becomes. A shadowgraph is an optical technique used to visualize non-uniformities in media. It works by casting shadows of these non-uniformities, which can be seen on a recording detector. As pe*****te more in less dense materials than in heavy and high z number materials an image of the object in the path of the light can be projected onto the detector screen much like an object standing in the way of visible light from a lamp casts shadows onto a background.

In a sense flash is similar to but where imaging captures the formation of a cloud x-ray imaging can see, for example, the debris formation inside the cloud. In this way the techniques are complementary to each other.

The image is taken together with our American distributor at thier test facillity "The Vault".
