Title

Advanced Light Source linear accelerator

Description

Advanced Light Source linear accelerator. Advanced Light Source electrons are generated by a high- intensity electron gun that can produce single or multiple bunches of electrons (each electron has an energy of 120,000 electron volts) in pulses of 2.5 nanoseconds (billionths of a second). These electrons then pass through the 120 accelerating chambers of the 5-meter-long linac (linear accelerator), where positive charges on the far wall of each chamber attract the electrons and accelerate them. Electrons emerging from the linac have reached an energy of 50 million electron volts and are traveling fast enough to go around the world 7-1/2 times in one second.
