Optimization of the injection and storage (see fig attached). At the end, injection with no losees!
Preparation for the orbit correction eluminating not working correctors. After several studies and iterations, we suceeded to correct the orbit (see the fig attached). Meanwhile, it seems that the BPM ri-c2/dg/bpm.04-lib.05 (quite certain as it did not respond to the corrector change) and probably ri-c1/dg/bpm.04-lib.03 do not give the proper readings. This point should be checked as soon as possible.
Problem with ChD of the ri-c2/dg/bpm.04-lib.05 (see the fig attached). We checked the connection in the rack5. We found that the BPM ri-c2/dg/bpm.04-lib.05 ChA was swaped with ChA BPM ri-c2/dg/bpm.06-lib.05 => Slava changed it. Now it is OK. BUT still ChD stays without signal. The problem is in the casemat probably. To be checked.
Starting the preparation for the first tune estimation. For this, we switched ON the sextupoles (see fig attached). Withour sextupoles, the FFT signal is too "noisy".
Optimization of the injection with the multiparameter optimizer RCDS, work in progress.
Alims IHM is updated by Slava to have separetly hor. and vert. correctors displayed.
18h30 End of the Shift.
