    keyword=Owl Shift Summary

    0030 Septum Tests, see 102986
    0130 Eugene leaves, no Moller tonite.
    0140 Sirish called, talked to MCC. We should get beam back in 10-20 min. He also mentioned that that we should forget about the Moller and Compton for tonite and go straight to production. Informed Geraud, he agreed.
    0200 Talked to MCC. Verified that we are not doing Moller and Compton tonite.
    0210 Setup for the modified momentum settings @ septum = 386.5A, see 102987 &
    0226 Got beam back. MCC checked bleed through & worked on beam position. Having trouble turning on feedback, but they will keep an eye on it. Reminded us that no beam was going through Compton. I said that that was okay. Also asked if we wanted the OTR in. I said no.
    0229 run 2198
    0237 Moved to Ref Cell Empty = -016psig & 000 torr
    0244 run 2199
    0250 Checked beam spot with spot++, beam spot is 2x2, need 3x3.
    0252 run 2200
    0258 Beam away, checking bleedthrough + other stuff, see 102988
    0312 run 2201
    0321 run 2202
    0322 Finally converged on good spot size, see 102992
    0326 Filled Ref Cell with N2
    0329 run 2203
    0340 Moved to Carbon Multi Foils
    0344 Beam away for test, do NMR = 34.9%, see 103005
    0357 Back to Carbon Multi Foils
    0400 Postion feedback flickers on and off, but MCC is doing a great job keeping it centered manually.
    0427 run 2204
    0434 Moving to Pol 3He @ 0 deg
    0441 run 2205
    0450 beam gone, tests
    0455 beam back, run 2206
    0508 Rotating from 0 to 270 deg
    0524 run 2207
    0542 run 2208
    0552 kin 5.11 finished!
    0555 changing momemtum to P0 = 2.288GeV (kin 5.12), see 103018
    0605 increased beam current from 7 microA to 8 microA, see 103021
    0609 septum hysteresis? see 103030
    0610 run 2209, junk, dipole did not set
    0615 run 2210
    0631 run 2211
    0638 moving to Ref Cell, rotating target to 0, see 103031
    0646 target = Ref Cell = Empty, MCC: IOC down = several mins
    0800 still no beam, when IOC crashed, lost 4 RF zone, beam back
