Summary:
20 amp quad mismatched and blew optics into Hall B. Wouldn't accept set point and jiggling the current slider didn't help either. DC Power contacted and corrected the issue.

A loss of communication between the PLC and the Hall B counting room display caused the screen to freeze on the last message. After rebooting the display, normal operation was restored, and it is now showing the correct stage. Network connectivity was verified.

Would not take setpoint. 20 Amp trim so DC power is investigating.

Figs. 1-3 shows the CW versions of the PCA analysis for mode 1 corresponding to ~0.1 Hz. Note the linac bpms now read likely the superposition of the two passes unlike in beam synch mode. Time series data shows ~6 oscillations in 60 s which is 0.1 Hz.

Took setpoint. We're not cycling magnets right now due to standing orders. Did not swap TC.

Attached is a plot of dispersion and beta functions at the IPM2A24 location used to locate placement of the labjack. Hard to see in the figure but IPM2A24 is near the peak of the black curve (horizontal dispersion etax).

Every root file is in cdaql2's /data/cdaq/hallc-online-ndelta_vcs2_2026/ROOTfiles

1. Elastic scattering

We took the electron singles and the dummy singles.
Full replays are almost done.
Calculate the efficiency regarding the proton absorption.

2. Comparison of simc and data.

*d and *a setting full replays are almost ready and simc is in /work/hallc/alphaE/sangbaek/simc_gfortran/worksim .
Elastics are there too.

Compare the data to the simulation.

3. Cross-checking 7a statistics

Exposure time set 4s to lighten surrounding area.

Well defined diffraction pattern isn't visible.

Fig 1 - slit out/ Fig 2 slit in/ Fig 3 - camera settings

Looks like several sources of diffraction, one from a circular aperture then one from the slits. Also of note that the image looks different before and after optics changes.
