This video camera was used by Steven Chu in a series of experiments where atoms were captured in a trap using laser. Atoms normally move at enormous speed, but Chu developed a method in 1985 for slowing them down with laser beams. When an atom is hit by light particles, photons, with particular energies, this affects its movement, like a shock. With six laser beams arranged two and two in opposite directions, around one million atoms could be captured. They formed a shimmering cloud the size of a pea, and the sequence could be recorded with a video camera.
Steven Chu donated the video camera to the Nobel Prize Museum in 2012. - Pristagare
