Booster Corrector Upgrade October William Pellico

History Olden days - Booster Correctors – DC supplies that had limited correction strength Quadrupoles limited to < 1 amp RMS current Dipoles limited to < 6 amps RMS current – Alignment – Done by Booster Personnel with no alignment fixtures – Very Limited Orbit Control – mostly low energy – Very Little harmonic control – mostly low energy Upgraded in late 80’s with ramped power – Allowed for higher current – due to ramp down at end of cycle. Still limited by RMS and slew rates!

Old Corrector ( Saddle Style Package )
