comparing harp traces yesterday versus now
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.
