BEAM THROUGH THE LAMBERTSON: This plot shows beam losses DOWNSTREAM of the Lambertson.

BEAM IN RHIC? This shows the Beam Loss Monitor signal in the vicinity of the Lambertson (near s = 590 meters) , and around the first half of the Sextant (s = 620 to 800 meters). The BLACK trace is the signal WITHOUT beam, the RED trace is WITH beam. There is a small but significant(?) signal half way around the sextant (s ~= 760 meters). NOTE: top and bottom plots have different horizontal scales.

BEAM ON FLAG yf1. The image on yf2 is similar, but we didn't catch it the second time before the gate problem occurred. The transmission to the end of y line is near 100% (Beam passed the Lamberson).
Beam with a lngitudinal bunch area of S = 0.3 eV-s/u.
See RHIC log #7, very near the end.
The following gif files show beam on the extreme upstream (uf2) and downstream (wf3) flags, in the AtR.
See RHIC log #8, circa page 40.

The following gif files are reconstuction for AGS Data, Au+77 at extraction, file dated 12/15/96 (same parameters as the gif file radon_121596.gif).
There are 6 plots which show the bunch rotating, 38 deg apart. There are a total of 47 traces used for each reconstruction. Each picture starts 10 traces after the previous picture. The pictures show 2 distinct blobs of charge rotating in the bucket, due to imperfect coalescence.
See RHIC log #6, page 122.
