#** Do we want 0,90,0,90, amorphous or 0,0,90,90,amorphous ? Elton: Suggests the 0,0,90,90,AMO to minimize beamline changes. Beni: Would like to see alternating 0,90,0,90,AMO to minimize systematics. David H: Mainz experience shows that changes on the scale of hours does not introduce systematics.

#** With the 3.5mm collimator, do we want more frequent harp scans at least at the beginning? Beam conditions are expected to be much more sensitive to drifts/focus changes. Elton: Play it by ear: start with one scan per day and check beam stability.

#* Beni: DAQ is taking data reading out all subsystems. Trigger used is Fcal/Bcal + CTOF. Rory: What is the status of the TOF trigger? Beni: TOF trigger firmware has been downloaded by Sasha and he has checked that relevant detectors are readout out. We need to push for further testing. Beni will ask Sasha to add the TOF trigger to the current configuration.

#* Empty target running (Rory): Plan is to take data with the neutral trigger, use Andrew's code to select e+/e- events and use those to generate vertex distributions. (They will review this at their local UMass meeting). Elton: Could possibly use the CTOF trigger to select mu+/mu- pairs and use those to look at the vertex distributions.
