4 Injector Emittance Measured Over 3 Days (0.25 nc) OTR screen at 135 MeV injector injector is is stable stable γε x = 0.91, γε y = 1.01 γε x γε y J. Welch wire-scanner at 250 MeV after BC1 2 June γε x = 0.83, γε y = 0.83

5 Normalized phase space centroid jitter after BC1 (~5% of rms beam size) 1-σ beam size RMS A xn = 4.9% RMS A yn = 4.1% Stability is not so far off of our goals (~10%) D. Ratner near end of linac (~15% of rms beam size, but sometimes larger) RMS A xn = 19.9% RMS A yn = 8.5% accelerator accelerator is is stable stable poor poor BPM BPM resolution resolution Q = 0.25 nc 2 June ΔE/E jitter < 0.1% ΔQ/Q jitter < 2%
