Modified physical cell length = 19.7605 [m] for all 24 periods from original MAD.
Removed non existing components and replaced with drift with MAD.
Changed scale factor for the quad and skew quad on the new correctors from kquad= 0.02178 to 0.0025 and from ksquad = 0.00889 to 0.004.
The input file is in CVS lattice depository
Lattice calculation with MAD
Review each magnet current on the input file.ORBMP, DogLegs, corrector…
Add alignment error to the input file.
Add alignment error table to B104.
B104 BOOSTER lattice with alignment error
Future plansFinish aperture scan. (50% left)
Make all tools to be available for operation.B75 Aperture scan (analysis with corrections.)Make references on alignment data sheet for
easier data gathering. B104 MAD (modify the input file and add alignment
table)
Ask for one week study time and move magnet at one location before shutdown.
Based on the results from alignment and aperture scan
Predict move, Move, Verify the move.
