  1. participants: G. Burtin, J.-P. Koutchouk, Y. Papaphilippou, F. Roncarolo, T. Sen, V. Shiltsev, J. Wenninger, F. Zimmermann help from BDI: J. Albertone, G. Ferioli, L. Jensen, R. Jones help from PS: E. Metral & colleagues measurements: beam loss (PMT), lifetime (BCT), wire scans, tunes, orbits, 1000-turn BPM data conditions: (A) 0 BBLR, (B) 1 BBLR, (C) 2 BBLR tunes (0.174,0.153) and (0.31,0.32) scans: BBLR-2 current, BBLR-2 distance, tunes QX, QY, & scraper (failed) BBLR MD 29.07., 30.07.04 lots of data to be analyzed

  2. optimum distance ~1 mm off optimum current >= 240 A (equal to other BBLR)

  3. base tunes 0.166, 0.154 large sensitivity, both BBLRs on

  4. base tunes 0.31, 0.32 perfect compensation @0.30-0.33, little @0.27-0.28
