------------------------------------------------------------------ MBXW D1 Separation Dipole ------------------------------------------------------------------ Version 1.0 7 October, 1998 Ranko Ostojic Quoted harmonic values are given in "units" of 10^-4 of the main quadrupole field at 17 mm reference radius. Notation: /: Mean of normal/skew harmonics D(bn)/D(an): Uncertainty of mean normal/skew harmonics sig(bn)/sig(an): Standard deviation of normal/skew harmonics Bn/An: Integrated harmonics (at lead ends) Gap 60 mm ref. radius R 17 mm COLLISION: ========= Integrated errors (body+ends) (unit) -------------------------------------------------------------------------- n D(bn) sig(bn) D(an) sig(an) -------------------------------------------------------------------------- 2 .0 .0 .0 .0 .0 .0 3 .3 .1 .06 .0 .0 .0 4 .0 .0 .0 .0 .0 .0 5 .1 .05 .03 .0 .0 .0 6 .0 .0 .0 .0 .0 .0 7 -.02 .005 .003 .0 .0 .0 8 .0 .0 .0 .0 .0 .0 9 -.02 .005 .003 .0 .0 .0 10 .0 .0 .0 .0 .0 .0 11 -.04 .005 .003 .0 .0 .0 12 .0 .0 .0 .0 .0 .0 13 .04 .005 .003 .0 .0 .0 -------------------------------------------------------------------------- Notes ===== 1) This table contains an estimate of integrated allowed errors for normal terms only. 2) Non-allowed terms, as well as skews are left open, to be determined later. They are small compared to the normal errors. 3) The errors correspond to a pole shim optimized for collision fields. Injection errors differ mainly in b3 and b5, while the other multipoles are almost identical.
