Data using electron beams on the positron accumulator ring (PAR) at 400 MeV, the injector synchrotron (IS) up to 7-GeV, and the main storage ring (SR) at 4.5 and 7 GeV address both transverse profiles and/or longitudinal bunch length. Recent measurements on OSR transported outside of the PAR and IS enclosures include transverse damping information. Streak camera and photodiode detectors have been used to measure bunch length compression (sigma)(sub t) = 1000 to 400 ps on the PAR and damping on the IS of (sigma)(sub t) = 200 to 75 ps. First transverse images have been recorded on the main ring from a single turn and for stored beam. 收起
