Category: BPM 
Subject: time series from 06/14 and 06/15 in top-up hybrid mode 
 
 Here is data during Linda Young's experiment started at 17h39 am on 6/14/04
 and lasting about 17.7hrs. The beam goes down after 14.5 hr due to a 
 machine study period.
 
 Attachment 1 shows the intensities. Experiments are ungoing so access 
 to 7ID-C sends the BPM values to large negative values. Linda's group 
 scanned the monochromator energy several times, detuned the mono 2nd crystal
 several times, starting around 8 hrs in the tserie. 
 
 Attachment 2 shows the 7ID-C X-ray BPM data. Note that the vertical beam 
 moves by about 200um peak to peak, so one expect the transmitted intensity to 
 vary quite a bit.
 
 Attachment 3 shows the APS XBPM data projected to the L5-20 plane
 Nothing much diffrent than the last few days.

 Attachment 4 shows the cryocooler information.
 
 Attachment 5 shows the piezo voltage, showing when a several tweaks happened
 during several energy scans of the mono.
