• 400 MeV Linac H- beam is injected into booster over several (up to 15) “turns”. The ion beam allows one to “cheat” Liouville’s theorem and inject (negative) beam on top of existing (positive) beam.
• The main magnets
of the Booster form a 15 Hz
offset resonant circuit , so the Booster field is continuously “ramping”, whether there is beam in the machine or not. Ramped elements limit the average rep rate to somewhat lower.
•From the Booster, beam can be directed to
• The Main
Injector
• MiniBooNE
(switch occurs in the MI-8 transfer line).
• The Radiation
Damage Facility (RDF) – actually, this
is the old main ring transfer line.
• A dump.
• One full booster “batch” sets a fundamental unit of protons throughout the accelerator complex (max
5E12).
•This is divided amongst 84 53 MHz RF buckets, which sets another fundamental sub-unit (max
6E10).
