According to the Sandia National Laboratories website reported that the laboratory and other laboratories and university researchers to develop the fastest so far to the multi-frame digital X-ray camera (UXI), the exposure time of only 1.5 nanoseconds, than the The best digital cameras are now 25 times faster.

High-speed multi-frame digital X-ray camera come out

A common problem faced by nuclear fusion physicists is that sometimes images that are continuously monitored suddenly "fragment" ruin the successful experiment, but no one can see what is happening. Sandia physicist John Porter said they want to make sure there is no such accident between image frames and frames. "Some experiments failed to predict ignition with the best models, there are too many factors that affect the model's data collection, and we need more data to make it more precise."

In precise data modeling, close observation over a short period of time is crucial. To this end, experts from the National Diagnostic Program (NDP) alliance agreed to further improve the quality of high-speed camera recordings in order to drive the development of next generation diagnostic devices for high energy density and inertial confinement fusion experiments.

Gregory Rochelle, head of Sandia's team, said existing CCD cameras take a single shot faster than UXI, but can not take continuous pictures with a resolution of 1.5 nanoseconds, and UXI can take pictures with finer resolution Check to find events on a smaller spatiotemporal than existing observational capabilities.

Mike Holmes, Sandia Team Leader in charge of developing camera sensors, said: "Creating high-precision, low-cost, networked UXI due to technical and financial reasons is critical to enabling future high energy density physics lab diagnostics." Currently , The camera has successfully conducted hundreds of experiments on Sandia's Z-Beam laser and LLNL's National Ignition Facility.

As planned, they will also work with General Atom to further shorten the imaging time to 20 picoseconds in a year.

Retractable Ceiling Fan With Bulb

This Retractable Ceiling Fan is consist of bulbs and blades. There are different numbers of bulbs for different needs. What's more, this retractable ceiling fan can be controlled by the remote including light and wind speeds. Also the blades of this ceiling fan will stretch out and put inside automatically when it turns on or off.
