Shift crew: Bob Michaels, Robert Feuerbach, Alexandre Camsonne
Started shift with finishing up Moller.
Then went to kinematics 4.2.3 - momentum 1.84, angle 25 degrees.
Runs:
Left.........Right......Parity
20247.....1247.......none...... BeO target check of spot size and location
20248.....1248......1189.......He3 longitudinal production run, beam halfwave OUT
............................................Note: The R-arm is junk (momentum changing)
20249.....1249.......1190......same, but R-arm momentum is stable now.
We started the charge asymmetry feedback. It works well ( < 10 ppm ).
20250.....1250.......1191......production, beam halfwave IN.
20251.....1251.......1192......same
Having met the statistical goal for longitudinal we move to reference cell.
20252......1252.......1193......empty reference
20253......1253.......1194......reference with 140 psi N2
Now we move to transverse target polarization
20254......1254........1195.....He3 transverse production run.
This completes kinematics 4.2.3.
Now we change momentum to 2.0 GeV, first cycling quads Q2 and Q3.
Kinematics 4.3.3 is set up, but ACC developed problems and we
waited for beam the last hour.
