keyword=Harp Positions Versus EPICS (11072008 Bull's eye scan)Here is my analysis of the bull's eye scan with a comparison of the beam
positions as reported by the harps and the EPICS readout.
In short, the harp versus epics dependence matches extremely well with the
bull's eye scan taken at the end of October. However, the new data still
indicate that there is a 1 mm offset in both the Harp A and B x positions
with respect to what the EPICS readout shows.
Figure 1 shows the new data compared to previous data taken during
E05-110 (CSR) and this past spring. Figure 2 shows the new data compared
to the data taking at the end of October. This last figure shows the
great agreement with the past scan.
