Preac(cellerator) and Linac
“Preac” - Coolest
looking thing at Fermilab. Static Cockroft-Walton generator accelerates H- ions from 0 to 750 KeV.
(Actually, there are two of these,
H- and I-)
“Old linac”-
200 MHz “Alvarez tubes” accelerate H-
ions from 750 keV to 116 MeV
“New linac”-
800 MHz “p cavities”
accelerate H- ions from 116 MeV to 400 MeV
Preac/Linac can deliver about 45 mA of current for about
35 usec at a 15 Hz repetition rate
