*Daily RC Report 5/25:*
Final installation tasks went well last evening:  fiber array detector 
inserted, annihilation counters calibrated and mounted, lead shielding 
of beam line & polarimeter in place and calibration of Compton 
polarimeter done and analysis happening now.  This morning lock-up of 
INJ/NL went smoothly, but ~6 hrs spent to deal w/ a network storm, 
viewers removed from service and ioc reboots.  During this period HCO of 
PEPPo beam line and successful operation of high current magnets 
achieved; parasitic checkout of the Compton analyzer magnet pick-up 
coils also performed and coils are working properly.  The remainder of 
DAY shift was used setup nice beam to FC2 w/ longitudinal polarization 
for PEPPo, ending with a calibration of the BCM0L02 receiver and DAQ vs. 
FC2.  As plans below show we'll commission beam setup through PEPPo on 
SWING, Compton checkout w/ beam on OWL and beam energy setup tomorrow DAY.

*Noteworthy items:*
