40 million images!!!!Product features

Item takes 40 million images a second from 2-nanosecond collisions. Item receives 4 trillion bits of information per second, processes signals and delivers 14 billion bits for further analysis.

Item contains super-speed boards and chips to process massive heaps information faster than you can imagine.

Don't think megapixels -- think megapictures!.

collision! in 2007!!Product background

In 2007, new Large Hadron Collider will start blasting protons (moving at 99.999999 percent of light-speed) against each other. The collider will recreate conditions just after the big bang, when mass and energy were almost infinitely compressed. As energy converts into mass, collisions will make many familiar (and therefore boring) elementary particles. To focus on new particles, calorimeter will take a 'snapshot' of collisions and help decide whether to save information on them, explains Pamela Klabbers, a high-energy physicist at University of Wisconsin-Madison who works on item.
