2. After checking that the Accumulator NMR is locked on, record the value of
A:BFIELD at each primary point. Retable A:NMRDO to adjacent points (if you are at
a primary point) if you had to make a change to it to get the NMR to re-lock.
3. At each primary point correct the tunes to Qx = 6.695 and Qy = 8.685 ( 0.003).
Generally one can use A:QSF1 to adjust the horizontal tune and A:QSD for the
vertical tune. Retable A:QSF1 (device 4) and A:QSD (device 77) to adjacent points.
4. At each primary point, correct the closed orbit (using P137) to the standard 8 GeV
central orbit (Archive file 9). The corrected orbit should match the reference orbit to
within 3 mm at all BPMs in both planes. Retable TRIMS/SHUNTS to adjacent
points when this correction is complete.
5. At each primary point, correct the chromaticity in each plane such that 0.4 < 4 0.8 as
measured by P43. The horizontal chromaticity is primarily corrected by A:SEX10 and
the vertical by A:SEX12. Retable the changed devices (devices 10 and 11) to adjacent
points.
6. This correction is not normally performed. At each primary point minimize dispersion
at A10, A30, and A50.
7. Measure ri and yt at each primary point.
8. Measure the horizontal and vertical aperture at each primary point. Note the caution
given in C.5 above regarding the use of the A50 scrapers.
9. Measure the lattice (take one bump BPM data) at energies near where E835 will be
operating.
After retabling, save the corrected ramp to your working deceleration ramp file.
Avoid overwriting ramp files that were recently written (i.e. within the last 24 hours).Revised 5 November 1999
