keyword=Qsq scans, also helicity errs
Doing a Qsq during spectrometer run 2059 and HAPPEX run 3624.
This time the scan rate is rather slow (will take ~15 min).
Note, previous HAPPEX run 3623 was a "fast" scan.
Problem: panguin reports a large number of helicity errors.
R-arm Qsq scanner rate has become extremely low.
L-arm Qsq scanner peaks at 200 Hz as we scan through peak.
In HAPPEX DAQ: Very small signal in L-arm, nothing in R-arm.
But we figure that with the present thin target we are down by
probably 2 orders of magnitude from "normal", so this is nothing
to panic about.
In spectr. DAQ, it is observed that the V2F signals for X,Y
move about in a reasonable way (both arms).
The L-arm ADC amplitude looks ok, but the R-arm has "died" since
when we did our first run. It was working earlier !
Scanning test is finished.
