Figures 1 and 2: 4E01 yesterday after injector setup versus this morning after the injector match change
Figures 3 and 4: 6E01 ditto
Figures 5 and 6: 8E01 ditto
Figures 7 and 8: AE01 ditto
Figures 9 and 10: 1E01 ditto this was a lot better yesterday
Figures 11 and 12: 2E01 yesterday versus this morning

I am not as perturbed as when I wrote the linked entry but the recommendation remains: I recommend doing an injector to NL match, checking tranmission, taking the usual harp traces and reestablishing beam to the halls.

Hall D's beam was quite out of spec, so I did a round of pathlength + ArcA correction (see fig 1) and steering into the dumplette (fig 2).

It seems inappropriate to have backed out of the match used by Yan, figure 1, without taking harp traces at all the even E01 locations. Losses are huge throughout the machine. In figure 2, all vertical axes are logarithmic. Having four of the windows at 10^3 is very unusual. The loss values in the bottom of figure 3 are also out of line.

I recommend doing an injector to NL match, checking tranmission, taking the usual harp traces and reestablishing beam to the halls.

Make sure the relevant PTW is on-issue before proceeding. Good to go.
