* Good - Run 5449 - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run5449_000 plots] - Cutting 300k-380k for some beam excursion, main det widths increase a bit too

== Pedestal/Calibrations Updates ==
* Devi has pedestals for SAMs and Main detectors - a new SAM pedestal run will need to be made with Devi's update

* We only have a Detector calibration - Caryn
+
* Run 5433 - BPM calibration
* We need to take pedestals for BPMs  - Amali
+
* Run 5434 - Unser BCM calibration
 +
* Run 5435, 5436 - Ca48 Det calibration
 +
* Run 5438 - PITA scan
  
 
== Issues ==
 
== Issues ==
  
* beam mod analyzer + plotter documentation
+
* This slug has too much inelastic state in the main dets, causing < 740 ppm widths
** get bmod analysis results into a panguin or prompt plot
+
* FFB had some auto-gain issue that messed with the BPMs in beam recovery, especially in Y (I suspect)
** get bmod analysis slopes into a online japan corrector for live regressed results
+
* dither correction / combiner map
+
* replace aggregator folder with develop
+
* make sure prex/crex data don't become mixed - fix grand agg plots
+
* '''fix burst definition as events passing cuts instead of fixed time intervals'''
+
** respin previous data
+
* make the combiner and mulc maps up to date
+
** fix missing channels and add new ones to aggregator
+
 
+
 
+
=== BCMs ===
+
* We want to use BCM an US as our normalizer and feedback BCM
+
* We need to check with Hall C and turn their feedback back on when they want it (still not 100% checked out that the EPICs print for Hall C is independent)
+
* We need an Unser curent ramp to calibrate these at 150 uA - Caryn
+
 
+
=== Target/Energy Tolerances ===
+
* How much of a excursion is dangerous for Ca48 frame issues?
+
* How well centered are we on the middle of the 9.4 mm Ca48 frame? [https://logbooks.jlab.org/entry/3752440 Beam Centering and Q^2 Log entry]
+
* Beam Energy Fluctuation tolerances with Excited States in HRS?? - FFB fixes this? Arc 1 vs 2 energy measurements and locks?
+
 
+
=== Commissioning ===
+
* Compton Chicane
+
* BMW commissioning
+
* Spot size on the target minimization
+
* FFB commissioning - Today day shift
+

=== BMOD Ana ===
 
'''note regarding beammod analysis:'''
 
 
Running the BeamMod analysis for a single run.
 
 
From ~/PREX/prompt/bmodAna/
 
create a new beammod root file from the already prompted run (####) using command
 
root -l -b -q bmodAna.C'(####,"max_input.list")'
 
 
then, to plot all combinations of alphas, deltas,and alpha/delta use the common
 
root -l -b -q plotAD.C'("path/to/rootfile/created/by/the/previous/command.root")
 
 
=== Counting Mode Downstream Detectors ===
 
* Devi has changed DS detectors to counting mode at 5420
