We offer a wide range of diagnostics to capture the data you need to evaluate your designs and verify performance, including the Cordin 330 framing/streak camera shown above. This camera provides high resolution, high frame rate cinematography, like the exmple above captured at 1 million frames/sec. High speed oscilloscopes like those pictured here provide 40 channels for recording transient electrical signals. We also lease equipment as needed, such as the SIM camera by Specialized Imaging, which captured the video at the far right with 50 ns exposure times. Our diagnostic and control system is modular, flexible, and portable, allowing us to easily integrate our advanced diagnostics, including ultra-high speed imaging, into your experiment - at our test site or yours.
Nanosecond Control & Recording
Our control and data acquisition system uses sub-nanosecond precision delay generators to control all critical events, including detonator firing, data recording, and image capture. Forty channels of high speed (2.5GS/s), long-record digitizers ensure that the signals from all of the various sensors on the test are captured with sub-nanosecond precision. A typical test might include pressure sensors, Piezo- and/or shorting pins for shock arrival time, foil switches, high speed framing and/or streak cameras, and a variety of other detectors selected to provide the data needed to evaluate performance.
High Speed Cameras
We currently have 2 synchronous framing cameras (Beckman & Whitley Model 189), 1 high speed streak camera (Cordin Model 136), and one combination framing/streak camera (Cordin Model 330, pictured above). We can provide framing camera imagery at up to 5 megaframes/second, and streak records up to 15 mm/microsecond for sub-nanosecond timing. We use a high energy CDU driving multiple xenon flash lamps for illumination, so imagery can be captured and evaluated before expending the explosives. We designed and built our own custom control system to allow easy integration of multiple cameras into "foreign" environments, such as your test facility. Need to add a camera to your test?

Under Development
We are constantly building new diagnostics and expanding our capabilities. Currently we're working to bring a 600 keV flash xray system online. This will allow us to capture short exposure (~30 ns) xray images at critical times during the operation of a device. The xrays can look through the fireball and detonation products and provide information about the internal shape, size, and density of shocked components for comparison against hydrocode models. Next on our "to do" list is Optical Doppler Velocimetry, which provides a non-contact method for measuring shock arrival time and material position and velocity over a distance of several centimeters. Like all of our diagnostics, these systems are designed for portability and ease of integration into "foreign" control systems.
