1. Booster Corrector Upgrade October 11 2010 William Pellico

2. 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!

3. Old Corrector ( Saddle Style Package )

4. New Corrector

5. Short Straight Corrector Package

6. Multi-Element Corrector Design Orange – horizontal dipole Bright green – vertical dipole Open green – normal quadrupole Red – skew quadrupole Magenta – normal sextupole Blue – skew sextupole Taken From: Booster Corrector Review 10 Oct 2006 Harding - Magnet Design and Fabrication

7. Booster Corrector Magnets New Booster Corrector Magnet Package Before Potting

8. Old - New OLD Horizontal trim – 4 amps Vertical trim – 5.6 amps Quadrupole – 1 amp Skew Quadrupole –.3 amps Short straights: Horizontal ramped, Vertical DC Long straights: Vertical ramped, Horizontal DC Sextupoles are in separate packages – 12 Horizontal – 9 Vertical New Normal Sextupole – 1.41 T/m – 2350 T/m/s Skew Sextupole – 1.41 T/m – 2350 T/m/s Horizontal Dipole – Be able to produce 1 cm of beam motion at highest beam energy (8GeV). – Be able to slew position 1 mm/ms up to the middle of the cycle – 0.009 T-m – 3.24 T-m/s Vertical Dipole – 0.015 T-m – 3.24 T-m/s Normal Quadrupole – 0.16 T – 88 T/s Skew Quadrupole – 0.008 T – 0.8 T/s
