Linac 2

It was built to obtain higher intensities and better stability than with the original Linac 1. Construction and running-in were completed in 1979, routine operation began in 1980. One sees its 3 tanks, with, at the top, the electrical connections for the quadrupoles (which are inside the drift-tubes) and watercooling. As Linac 1, Linac 2 is driven at 202.56 MHz and accelerates protons to 50 MeV for injection into the 4 rings of the PS Booster.
