Entry number 164763

I calibrated the Hall A IA cell, which was a necessary step for commissioning 
feedback.  The S2 picomotor was tweaked to increase the dynamic range, which 
should be of use when Hall C turns on.

The measured slope is 393 ppm/Volt (measured in bcm4).  A current scan should 
be performed to set the pedestal of this bcm sometime (and then this slope 
should be recalibrated from this run).

Run 7044  - test before S2 tweak.  Ended after S2 tweak, with IA=1.

Run 7045 - IA calibration scan.  Small screw up caused brief time
with IA = 3, but scandata1=0... whoops.  Also, IA=1 setpoint was somehow not 
recorded... low beam cut, maybe?

Run 7046 - short test run, with IA=5.
