Flash X-Ray Imaging System
Flash X-Ray is a system used in ballistic discipline, especially in terminal ballistics, for events that cannot be imaged with conventional photographic technics. The system is capable of acquiring images for very fast events lasting in the order of microseconds. Flash X-Ray is generated by the system for a few nanoseconds and after hitting the moving object, it forms a negative image on the X-Ray film.
Unlike conventional imaging methods, the Flash X-Ray system can get images in ballistic experiments containing dust, smoke and flame. A Flash X-Ray tube creates just one image at a predetermined time. By using more than one tube, several images can be obtained at different times enabling to follow the path of the moving object.
The Flash X-Ray System used in TÜBİTAK SAGE is capable of creating six different images in total belonging to four different times. Therefore, it is possible to investigate the event by taking images from different angles and times.
Flash X-Ray system in TÜBİTAK SAGE is a mobile system and can be set to any test location in Turkey for service.

- Flash X-Ray System can be used in any high speed ballistic experiments. Shaped charge jet and explosively formed projectiles, interactions of penetrators with targets, investigating beyond armor effects, examination of space station’s armor shield against meteoroid impact, explosion reactive armor studies, impact fuze and safe&arm system tests are examples of Flash X-Ray system applications.
High Speed Impact Testing
Light Gas Gun is an experimental test set-up providing projectile and fragment impact with high velocity in laboratory conditions.
The system has two different barrels having 12 mm and 25 mm internal diameters, and provides testing specimens with diameters lower than 23 mm.
- Barrel diameter: 12 mm and 25 mm
- Specimen outlet velocity: 100-1000 m/s
- Velocity measurement: 0-1500 m/s.
The system provides tests for material characterization at high strain rates, armors, Taylor and inverse Taylor, protective clothes and safety equipment (bulletproof glass, helmet, vest etc.) resisting to fragment and projectiles.
For safety reasons, there is a target cabin at the exit of the barrel that has transparent walls providing high speed camera recording
