A PARTICLE ACCELERATOR ON A CHIP. “Researchers have used commercial lasers to speed up the electrons instead of microwaves, which are typically used. They were amazed to see an incredible acceleration in such small distances. The device is three millimeters long. The advantage is cost. Since this tiny device is made with a laser, it can be mass-produced. This development makes a particle accelerator available to any lab for a few thousand dollars rather than the billions of dollars that a present day conventional technology costs.”
